associated with Antarctic marine sponges showed the higher xylanolytic activity at low temperatures when grown on beechwood or birchwood xylan and wheat bran, than on wheat straw and oat bran (Del-Cid et al., 2014) (Supplementary Table 1). Biochem. The fungal life cycle and mediating interactions between the fungus and host have led to the evolution of biochemical pathways for the synthesis of unusual secondary metabolites that have found many potential applications in anticancer and antimicrobial studies (Yarden, 2014; Hasan et al., 2015; Li et al., 2016; Deshmukh et al., 2017). 8:2536. doi: 10.3389/fmicb.2017.02536, Dhale, M. A., and Vijay-Raj, A. S. (2009). Although the marine fungi Isaria felina (accepted name Beauveria felina) and S. brevicaulis grew well on the submerged rice bran without the addition of salts, they exhibited mainly the β-1,3-glucanase and polymannuronate lyase activities reached for 7 days to 600 U/mg and 280 U/mg, respectively (Balabanova et al., 2018). LF562, Bartalinia robillardoides LF550, Penicillium pinophilum LF458, S. brevicaulis LF580, and Pestalotiopsis sp. 5, 765–774. Supplement Obligate aerobes need oxygen to oxidize substrates (for example sugars and fats) in order to obtain energy. Marine fungi are ex-pected to be found in parts that can be submerged, while Only two cosmopolitan taxa of obligate marine fungi were isolated in this study, namely Ceriosporopsis halima and Lulwoana uniseptata (=Zalerion maritimum) (Hughes, 1986, Jones, 1993). doi: 10.15373/2249555X/MAR2013/102, Sette, L.

Facultative forms are originally sourced from terrestrial or fresh water region but they are able to colonize and adopt with the marine habitat and the obligate are extensively live in marine ecosystem (Kohlmeyer and Kohlmeyer, 1979). Life Sci. (2015). Marine fungi are species of fungi that live in marine or estuarine environments. Marine fungi: their ecology and molecular diversity. Case study on the extra cellular enzyme of marine fungi associated with mangrove driftwood of Muthupet Mangrove. Moen, E., Alvarez-Colsa, P., Larsen, B. (2015). The genome sequencing of the psychrotrophic strain Cadophora malorum revealed deficient in cellulase genes, but its putative alginate lyase could be acquired due to the adaptation to marine environment (Rédou et al., 2016). Facultative marine fungi normally occupy terrestrial or freshwater habitats, but are capable of living or even sporulating in a marine habitat. Xylan degrading enzymes from fungal sources. Biosafety Res. Taking into account that environmental pollution is largely related to the saline conditions, the use of the lignin-degrading enzymes from the marine-derived fungi can be considered strategic (Zilly et al., 2011; Sette and Santos, 2013; Bovio et al., 2017; Barnes et al., 2018). Polymerization 63–86. Fucoidanases. Cellulose, hemicellulose, and pectin are the main polysaccharides of plant cell walls that are strengthened by an aromatic heteropolymer lignin preventing their enzymatic digestion (Ochoa-Villarreal et al., 2012). Mar. Biotechnol. NCi6 and Phlebia sp. Alsheikh-Hussain, A., Altenaiji, E. M., and Yousef, L. F. (2014). Biodegrad. Discovery of the genes involved in the delignification pathways in marine fungi can help to understand their mechanisms to exploit their potential as efficient biomarkers for bioremediation. Recently, the full-length or partial sequences of the multigene laccases from the marine-derived fungi with bioremediation potential have appeared in GenBank (Supplementary Table 3). Floridean starch granules outside of plastids, and consisting mostly of a-D-glucose and insoluble amylopectin, are the main storage polysaccharide in the red seaweeds (Kim, 2011). (2011). Investigation of marine-derived fungal diversity and their exploitable biological activities. Bot. doi: 10.1016/j.micres.2009.09.005, Minegishi, H., Miura, T., Yoshida, Y., Usami, R., and Abe, F. (2006). Fungal cellulases from mangrove forests – a short review. Rev. (2010). (2009). This fact suggests a broadened substrate specificity of the marine fungal enzymes that may be conditioned by the adaptation of once soil fungi to a marine life style in the medium with the higher salt concentrations, depleted nutritional resources and/or fungal-marine habitant relationships (Kumar et al., 2015). About 444 species of marine fungi have been described, including seven genera and ten species of basidiomycetes, and 177 g… (2005). Therefore, marine fungi can also possess pectinolytic enzymes with unusual structure and specificity distinguished by the affinity to the algal pectin-like polysaccharides. doi: 10.1074/jbc.M405867200, Chamorro, S., Viveros, A., Alvarez, I., Vega, E., and Brenes, A. Purification and partial characterization of an extracellular alginate lyase from Aspergillus oryzae isolated from brown seaweed. This suggests that the marine strain S. brevicaulis LF580 may be able to degrade a larger variety of plant substrates than some terrestrial lignocellulolytic fungi (Kumar et al., 2015). A more detailed discussion about marine fungi and obligate marine species has been presented by Kohlmeyer and Kohlmeyer, 1979. In some macroalgae, where cellulose is absent (Chlorophyceae and Rhodophyta), xylan forms a highly crystalline fiber-like material. Thomas, L., Joseph, A., Singhania, R. R., Patel, A. K., and Pandey, A. The most represented genera Penicillium, Cladosporium, and Acremonium associated with seagrass, Posidonia oceanica, were rich in the strains able to produce ligninolytic enzymes and tannases useful at degrading and detoxifying lignocellulose residues in the presence of high salt concentrations (Panno et al., 2013). Although the data on marine fungi with the sequenced genomes are restricted, they carry sufficient information about the common ancestral forms of life with terrestrial fungi such as the capability of utilizing plant polysaccharide complexes for their growth (Arfi et al., 2013; Kumar et al., 2015). Twenty-nine of them showed more than 50% of the tannase activity in the saline conditions that could make the plant eatable to most of the fauna present in the sea (Panno et al., 2013). According to Kohlmeyer and Kohlmeyer (1979), “obligate marine fungi” are those that grow and sporulate exclusively in marine or estuarine habitat; “facultative marine fungi” are those from freshwater or terrestrial milieus able to grow (and possibly also sporulate) in the marine environment. Production of amylase from marine fungus using spoiled banana fruit as a substrate. Int. 29, 719–739. The fungal enzymes degrading algal polysaccharides can be categorized into the same protein families and classes according to the CAZy classification as the plant-polysaccharide-degrading enzymes (Figure 1 and Supplementary Table 2). Drugs. After the Deepwater Horizon oil spill, we heard a lot about oil-eating bacteria. Diversity, ecological role and potential biotechnological applications of marine fungi associated to the seagrass Posidonia oceanica. a terrestrial or fresh water fungi that is able to grown or even sporulate in Sea or Estuary. The genes encoding CAZymes in the presence of polymers or their partially hydrolyzed molecules have been shown to be repressed under the growth conditions on simple substrates such as glucose, when the fungus does not need the production of the polysaccharide-degrading enzymes for the nutrition (Aro et al., 2005). The laccase activity was completely inhibited, and the number and diversity of ligninolytic enzymes decreased in Pestalotiopsis sp. In general, marine fungi are classified as either obligate or facultative. Microb. Marine fungi are a diverse group of opportunistic and obligate organisms isolated from marine environments [1, 2]. The CAZymes have been well surveyed in the terrestrial basidiomycetes and ascomycetes (van den Brink and de Vries, 2011; Rytioja et al., 2014). Front. The backbone chains of hemicelluloses have many branches as attached monomers of D-galactose, D-xylose, L-arabinose, and D-glucuronic acid. (2015). Consequently, several enzymes are needed to completely degrade these polysaccharides. EVALUATION OF BIOLOGICALLY ACTIVE MOLECULES ISOLATED FROM OBLIGATE MARINE FUNGI Technol. From the green alga Ulva sp., the endophytic and obligate marine fungus Ascochyta salicorniae was isolated. Brown seaweeds were reported to contain about 14% of extra carbohydrates in the form of alginate associated with phenolic compounds (Synytsya et al., 2015; Deniaud-Bouet et al., 2017; Raimundo et al., 2017). Marine-derived fungi from Kappaphycus alvarezii and K. striatum as potential causative agents of ice-ice disease in farmed seaweeds. There remains more questions than answers. Our understanding of the fungi that inhabit our oceans (an area covering more than 70% of our planet’s surface) is quite limited, compared to what we know of their terrestrial brethren. What exactly are they doing? NIOM-02 showed an increase of amylase activity at cultivation on wheat and corn flour by submerged fermentation (SmF) (246 U mg-1) and by SSF (18 U mg-1) in comparison with the activity on sugar cane bagasse (Dhale and Vijay-Raj, 2009).

Taxonomically characterized marine fungi are belongs to either facultative or obligate forms. Tricking Arthrinium malaysianum into producing industrially important enzymes under 2-deoxy D-glucose treatment. The cellulase-free filtrate of Aspergillus niger isolated from the detritus of decaying mangrove leaves grown on oat spelts xylan or sugarcane bagasse containing 580 U L-1 of xylanase could bleach sugarcane bagasse pulp for 60-min at 55°C (Raghukumar et al., 2004a). doi: 10.1128/genomeA.00467-16, Redouan, E., Cedric, D., Emmanuel, P., Mohamed, E. G., Bernard, C., Philippe, M., et al. Influence of NaCl and Na2SO4 on the kinetics and dye decolorization ability of crude laccase from Ganoderma lucidum. For the efficient bioconversion of plant and algae material, microorganisms or enzymes capable of degrading the indigestible cell wall polysaccharide complexes are the most valuable for biotechnology. Bacteria have been suggested to play a more important role in the submerged macroalgae degradation than fungi (Raghukumar, 2017). (2013). Sci. 1B), the anamorphs (Fig. Am. Fungi have been found to be the only organisms in which there are all three LPMO families AA9, AA10, and AA11, indicating the importance of the oxidative enzymes promotive of lignocellulose utilization for their lifestyle (Morgenstern et al., 2014). Historically, marine fungi have been understudied. According to the chemical composition of the branches, fucoidans can be divided into xylofucoglycuronans and glycuronogalactofucans (Kim, 2011). doi: 10.1007/s00248-002-1055-7, Mai, Z., Su, H., and Zhang, S. (2016). For example, the OTU_13192 composed of 62 reads was identified as Corollospora maritima . Commun. Some marine fungal strains grew on the ulvan-containing material, indicating that they may be a source for novel ulvan lyases and GHs as it was found in marine bacteria producing the enzymes of new families PL24-25 and GH105 (Solis et al., 2010; Collén et al., 2014; Gnavi et al., 2017; Ulaganathan et al., 2017). (1979) stated that marine fungi can be categorized into two groups, namely the obligate marine fungi which are able to grow and sporulate exclusively in marine and estuarine habitat; and facultative marine fungi which originated from freshwater and terrestrial habitats but are able to grow and possibly sporulate in marine … Food Sci. doi: 10.1007/s12010-013-0551-1, Deniaud-Bouet, E., Hardouin, K., Potin, P., Kloareg, B., and Herve, C.

Many unknown fungal species, even at higher taxonomic levels in the Chytridiomycota forming an ancient evolutionary lineage, Ascomycota, and Basidiomycota found in the deep-sea water, and the molecular clock estimates of their rRNA evolution suggested the hypothesis that fungi initially diversified in the ocean before they colonized the land (∼400 million years ago) (Le Calvez et al., 2009; Manohar and Raghukumar, 2013). Transcriptional regulation of plant cell wall degradation by filamentous fungi. Appl. Obligate marine fungi are cultured directly from their sporulating structures in decomposing wood and other substrates. The lignocellulolytic pathways of Myceliophthora thermophila varied with different plant substrates, reflecting the plant cell-wall polysaccharide structure and content (Kolbusz et al., 2014). doi: 10.1146/annurev-marine-120710-100802, Richards, T. A., Leonard, G., Mahe, F., del Campo, J., Romac, S., Jones, M. D. M., et al. Marine fungi have been classified as either obli-gate or facultative: obligate marine fungi grow exclu-sively in a marine habitat, whereas facultative marine fungi are of freshwater or terrestrial origin but are able to thrive in marine environments [7–9]. KF525, S. brevicaulis LF580, and Tritirachium sp. 35, 197–202. J. Chem. Lignin peroxidase (LiP) (E.C:1.11.1.14) and manganese-dependent peroxidase (MnP) (EC 1.11.1.13) and laccase (Lac) (EC1.10.3.2) are the other major lignin-degrading enzymes with great potential for industrial applications (Bonugli-Santos et al., 2010, 2015; Panno et al., 2013). Imagine if an oak lassoed you as you ran past. The relatively more recent application of DNA sequencing techniques has provided additional insights into marine fungal diversity and has stimulated a new wave of interest into their functional roles in marine ecosystems – though the DNA sequencing techniques currently in use were designed using largely terrestrial representatives, and so are greatly biased towards the fungal subkingdom Dikarya, resulting in poor representation of other fungal groups known to occupy marine habitats. LS drew Figure 1 and assisted in the preparation of Supplementary Table 1. Thus, fungal genera/species affiliated to Halosphaeriaceae are usually considered as obligate marine fungi (Jones et al., 2006). NCi6 in the presence of salt, but simultaneously with an increase of xylanase and cellulase activities (Arfi et al., 2013) (Supplementary Table 2). The presence of salt modified the lignocellulolytic enzyme composition of the salt-adapted mangrove fungus Pestalotiopsis sp. Protoc. 2012). These fungi are now often included in screens for novel metabolites, while less attention has been given to their production of hydrolytic enzymes. doi: 10.1007/s13225-015-0339-4.

In addition, white-rot fungi have up to 12 members of ligninolytic peroxidases from the AA2 family, distinguishing them from brown-rot fungi, which contain no AA2 members (Floudas et al., 2012; Hori et al., 2013; Levasseur et al., 2013). The first results in the study of antimicrobial activity of facultative and obligatory marine fungi of the Black Sea, as well as the ability of fungi to luminescence, are … The results showed that 16 β-glucosidases of the GH1, and 6 glucan β-1,3-glucosidases of the GH5 family involved in cell wall biogenesis/degradation was significantly up-regulated. Mangrove fungi producing thermostable and active xylanases in the presence of residual sulfated lignin are highly desirable in the enzymatic treatment of wood pulp after alkaline extraction. doi: 10.1038/nprot.2009.233, Kohout, P., Sýkorová, Z., Ctvrtlíková, M., Rydlová, J., Suda, J., Vohník, M., et al. The polyphenolic compounds involved in a defensive function have been found to be extremely abundant in the seagrass, P. oceanica, mainly in rhizomes and leaves (Panno et al., 2013). (2013). Starch is the storage polysaccharide in the green algae chloroplasts similarly to plants (Kim, 2011). Nat.

Novel cold-adaptive Penicillium strain FS010 secreting thermo-labile xylanase isolated from Yellow Sea. Some marine fungi even live on terrestrial plants (these would be the facultative type). Thus, an alginate lyase from the Aspergillus oryzae associated with brown seaweed was unique due to cleaving the β-1,4 glycosidic bond between polyM and polyG blocks of sodium alginate resulted in a higher polyM/polyG ratio in comparison with the acid hydrolysis (Singh et al., 2011). Nearly 530 species of marine fungi reported from India included in 321 genera. A high occurrence of polygalacturonase producers (30%) among the deep-sea yeast collected from the mud of Sagami Bay (1100–1400 m) capable of degrading plant pectin was inexplicable (Minegishi et al., 2006). (2010). The first marine fungus was described about 160 years ago. 30, 685–694. Therefore, the gene sequences encoding CAZymes of marine fungi should be explored on their functionality to use in the genetic modification and metabolic improvement of the biotechnological strains, particularly for their cultivation at the high salt concentrations or other extreme conditions in industry or bioremediation of soils and water. The β-1,3-linkage, which is abundant in marine substrates, has been found to be degraded by enzymes belonging to the GH families: GH3, GH5, GH16, GH17, GH26, GH55, GH64, GH81, and GH131 (Figure 1 and Supplementary Table 2b). J. Ind. It has been found that brown algae evolutionary distinguished from land plants and other algae by their cell wall structure. If anything, fungi are an important consumer of plant and animal residues as well as chemical pollutions of the marine environments (Harms et al., 2011; Richards et al., 2012). 46, 32–37. 344, 1670–1675. doi: 10.1007/s10811-010-9576-9.

The production of accessory depolymerizing enzymes synergistically working with the backbone-degrading enzymes is regulated mainly at the transcriptional level in filamentous fungi for more deeply degradation of plant polysaccharide complexes (Aro et al., 2005). The fungal filtrate also showed moderate activities of xylosidase (0.26 U mL-1) and arabinofuranosidase that could act synergistically with xylanase at attacking xylan. 109, 112–120. Of which 424 Ascomycota (251 genera) 94 Mitosporic fungi (61 genera) and 12 Basidiomycota (9 genera). Seaweed polysaccharides and derived oligosaccharides stimulate defense responses and protection against pathogens in plants. CBMAI 1330 have structural features that groups them phylogenetically into the proteins from ascomycetes derived from the marine environments (Passarini et al., 2015). Microbial laccases and their applications: a review. Marine fungi are not a taxonomically or physiologically defined group of organisms; rather, they are an ecologically defined group. Interestingly, a small proportion of sequences were classified to obligate marine fungi (e.g. 99, 1011–1020. Transcriptome and exoproteome analysis of utilization of plant-derived biomass by Myceliophthora thermophila. 8:600. doi: 10.3389/fmicb.2017.00600, Garcia-Vaquero, M., Rajauria, G., O’Doherty, J. V., and Sweeney, T. (2017). Rather, the classical definition of ‘marine’ is based more on the ecology of the organism where marine fungi are classified into obligate and facultative forms: obligate marine fungi are those that grow and sporulate exclusively in a marine or estuarine habitat, and facultative marine fungi are those that also occur in … Fucoidan degrading fungal strains: screening, morphometric evaluation, and influence of medium composition. Surprising spectra of root-associated fungi in submerged aquatic plants. Lignin-degrading marine fungi have been mostly identified in mangroves and seagrasses (Raghukumar, 2008; Arfi et al., 2013; Panno et al., 2013; Sette and Santos, 2013; Bonugli-Santos et al., 2015).

Laccases: a never-ending story. Enzym. The capability of metabolic utilization of plant or macroalgae polysaccharides allows for an increase in the production of fungal biomass enriched by mycelium proteins and extracellular enzymes that can be used in animal or fish feeding, or in the bioremediation of soils and water (Supplementary Table 1). The plant-degrading CAZymes such as cellulases, hemicellulases, ligninases, and pectinases, and the accessory debranching enzymes belong to the following classes: GHs, glycosyl transferases (GTs), polysaccharide lyases (PLs), CEs, and AAs that can be linked to carbohydrate-binding modules CBMs (Guillén et al., 2010; van den Brink and de Vries, 2011; Rytioja et al., 2014). doi: 10.5772/46094, Otero, I. V. R., Ferro, M., Bacci, M., Ferreira, H., and Sette, L. D. (2017). Feng, X., Chen, H., Xue, D., and Yao, S. (2013). Studying the carbohydrate-active enzymes (CAZymes), particularly the main and concomitant polysaccharide-depolymerizing enzymes in marine fungi, allow for the elucidation of mechanisms of their action and advantages for biotechnological use. In the oxidative method for the industrial decolorization or delignification with the use of laccase or the laccase/mediator system, the redox potential difference between the enzyme and the substrate is a relevant indicator of its biodegradability (Giardina et al., 2010; Desai and Nityanand, 2011).

What cool chemical compounds are they hiding? In addition, the absence of simple methods for quantitative determination of the fucoidanase activity and the use of structurally uncharacterized fucans hamper exploring fucoidanases and finding the new enzymes (Ermakova et al., 2015). Chem. J. Appl. Xylanases are used concurrently with cellulases and pectinases for clarifying juices, the liquefaction of vegetables and fruits as well as in the pretreatment of forage crops to improve the digestibility of ruminant feeds and to facilitate composting (Nadu et al., 2011; Goddard-Borger et al., 2012). Mangrove-associated fungi have been divided into two groups: those that are submerged at high tide and those that are not. A., Vieira, J. M. F., Videira, A., Meirelles, L. A., Rodrigues, A., Taniwaki, M. H., et al. Fungi are thought to have a relatively high tolerance to hydrocarbons, and more than 100 genera are known to play important roles in biodegradation of hydrocarbons in soils and sediments. Avaialable at: http://tolweb.org/Eukaryotes/3/2009.10.28, Kim, S.-K. (2011). A. Indian J. Appl. The fungus was also able to grow without salt and produced maximum biomass and pectinolytic enzymes (PG I, PL) in a liquid medium (Supplementary Table 1). It is known that the enzymatic breakdown of cellulose in fungi is achieved by GHs from the families 5, 6, 7, 12, and 45 distinguished by the mode of enzymatic action and the substrate specificity: cellulose 1,4-β-cellobiohydrolyses (reducing end) (EC 3.2.1.176; CBH I; GH7); β-1,4-endoglucanases (EC 3.2.1.4; EG; GH 5,6,7,12,45), exo-β-glucanases or cellobiohydrolases (non-reducing end) (EC 3.2.1.91; CBHII; GH 6,7), β-glucosidases (EC 3.2.1.21; BGL; GH 1,3), and the auxiliary enzymes (AA) (Supplementary Table 2).

Distribution and diversity of enzymes for polysaccharide degradation in fungi. KF079 at a similar rate as glucose demonstrated the efficiency with which their amylases and glucanases were expressed (Wang et al., 2016) (Supplementary Table 1). 37, 326–328. KF525, Tritirachium sp. Many discoveries are expected in the coming years from this yet poorly explored group of microorganisms, particularly about their enzymes specific toward the marine substrates. The exogenous addition of 2-DG to fungal cells in a growth media caused the glucose starvation-like response. Arfi, Y., Chevret, D., Henrissat, B., Berrin, J. G., Levasseur, A., and Record, E. (2013). (2012). A large number of obligate marine fungi thrive on mangrove wood, pneumatophores and submerged mangrove leaf litter. A novel unsaturated β-glucuronyl hydrolase involved in ulvan degradation unveils the versatility of stereochemistry requirements in family GH105. The fungal pectinolytic enzymes that degrade multiple pectic molecules have been suggested to be good indicators of the association between fungi and the land plant lineage (Chang et al., 2015). doi: 10.1016/j.rser.2015.10.132, Kumar, A., Henrissat, B., Arvas, M., Syed, M.

Although the total number of fungi on earth is estimated to be about 1.5 million, only a meagre number of obligate marine fungi , about 450 mycenaean and 50 straminipilan fungi have been described so far. Production of laccase, manganese peroxidase and lignin peroxidase by Brazilian marine-derived fungi. 78, 614–649. Iran. The main polysaccharide in Acetabularia, Codium, and the Halicoryne genera, and in some red algae such as Porphyra umbilicales is β-1,4-mannan, which is a structural and reserve component of green algae (siphonaceous) (Goddard-Borger et al., 2012; Synytsya et al., 2015) (Figure 1). More than 80% of the marine fungi belong to the group Ascomycota. Most ocean fungi live on animals and plants, or dead and decaying matter. Biotechnol. Thus, the lignicolous marine fungus Havispora longyearbyenensis from Arctic water significantly reduced even the growth without salinity at 4°C (Pang et al., 2011). Microbiol. In the same way, low molecular weight carbohydrates produced during destruction of polymers could induce the expression of other CAZyme genes (Coradetti et al., 2012; Hori et al., 2013; Mukherjee et al., 2016). Low hemicellulase activities in the marine-derived fungi from brown algae [≤0.02 U of β-xylosidase (BXL) activity per mL of crude fungal extract] were suggested to be due to the low content of hemicellulose in brown algae (Borines et al., 2011; Hong et al., 2015) (Supplementary Table 1). Marine fungi are either completely restricted to oceanic habitats (obligate), or able to grow there as an extension of their normal range (facultative). In the cases of putative cleaving β-1,3-glucans, the auxiliary domains CBM43 and CBM13 were shown to associate with GH5 and GH17, respectively (Blackman et al., 2014). Nearly 200 CAZyme families with more than 300 representatives have been identified in the predicted fungal proteomes (Zhao et al., 2014). Genomewide analysis of polysaccharides degrading enzymes in 11 white- and brown-rot Polyporales provides insight into mechanisms of wood decay. Microbiol. Taxonomically characterized marine fungi are belongs to either facultative or obligate forms. isolated from an obligate marine fungus, the compound had been previously isolated from a terrestrial species (Kupka et al., 1981). Polym. We know they’re there, but we have only a vague idea of what they’re doing. An enzyme with GH5 and GH26 catalytic domains that possessed beta-1,3-1,4-endoglucanase activity contained CBM11 (Carvalho et al., 2004). (2017). However, the pectin-depolymerase activities were often not found in some marine fungi, possibly due to the structure-function features of the enzymes, or the absence of their up-regulation in the presence of plant-derived substrates used in experiments. However, even a combination of cultures, microscopy, and DNA-based methods have determined that the vast majority of fungi identified from marine environments belong to Dikarya. Microbiol. Therefore, an idea of using marine fungi for the plant and algae biotransformation has been successfully exploited for the production of low-cost edible protein and highly valuable biochemicals, as well as for wastewater treatments (Beena et al., 2011; Harms et al., 2011; van Leeuwen et al., 2012). Obligate marine fungi grow exclusively in the marine habitat while wholly or sporadically submerged in sea water. Arthrinium phaeospermum and Fusarium equiseti grew with the highest rate in saline conditions, indicating the intrinsic halo-tolerance due to the long-time adaptation to a marine life style (Lee et al., 2015). The cellulose and hemicellulose content of the seaweeds has been surveyed to be 2–10% and 9% dry weight, respectively. Arch. FEBS Lett. Among 18 marine-derived morphospecies, Phoma sp., Aspergillus ochraceus, and A. terreus, possessed also carrageenase activity (Solis et al., 2010). 38, 142–149. doi: 10.15171/ijb.1155, Al-Nasrawi, H. (2012). Biol. Many extra- and intracellular enzymes of marine fungi such as GHs, nucleases, proteases, and lipases involved in the degradation of cell walls, DNA, proteins, and other organic matter have been structurally or/and biochemically characterized and showed the higher specific activity and effectiveness in comparison with those from their terrestrial counterparts (Nielsen et al., 2007; Kamat et al., 2008; Beena et al., 2011; Harms et al., 2011; Balabanova et al., 2012; van Leeuwen et al., 2012). Copyright © 2017 Texas Saltwater Fishing Magazine. Both fungi appeared to be appropriately labeled “marine,” judging by criteria currently in general use. Family 6 carbohydrate binding modules recognize the non-reducing end of beta-1,3-linked glucans by presenting a unique ligand binding surface. Genome Biol. However, their enzymatic profile included about 25–37 U/mg activities of agarase, alginate lyase, carragenase and fucoidanase during the first 4 days of cultivation dropped almost to zero at the following 7 days, probably, due to the growth on the plant substrate (Balabanova et al., 2018). The marine-derived strains Basidiomycete MEG2, Pezizomycetes CMCA22 and GPG3 showed an increased the EG activity at low temperatures with the addition of sophorose precursor, cellobiose (Alsheikh-Hussain et al., 2014). Int. Curr. Probably for the same reason, the sequenced marine strain Scopulariopsis brevicaulis LF580 growing on alginate or ulvans as the sole carbon source does not have any known families of algae polysaccharide-degrading enzymes such as alginate lyases (PL7,-15,-17) or ulvan lyases (PL24,-25) (Supplementary Tables 1, 2a,b). et al. Secondary metabolites of fungi from marine habitats. Filamentous fungi possess the metabolic capacity to degrade environment organic matter, much of which is the plant and algae material enriched with the cell wall carbohydrates and polyphenol complexes that frequently can be assimilated by only marine fungi. Moreover, there is abundant evidence for multiple recolonizations of the ocean by fungi (Spatafora et al., 1998; Richards et al., 2012). J. Appl. doi: 10.3390/ijms17081360, Manohar, C.

The fungal endo-β-1,4-glucuronan polysaccharide lyase isolated from T. reesei was applied to the glucuronan depolymerization of the green seaweed Ulva lactuca for the production of bioactive glucuronic acid oligosaccharides (Redouan et al., 2009). Renew. Facultative marine fungi are those that normally occupy freshwater or terrestrial habitats but are able to grow (and … Marine fungal biotechnology: an ecological perspective. Marine fungi are species of fungi that live in marine or estuarine environments. The discovery of thraustochytrids in 1936 and that of obligate marine, lignicolous fungi in 1944 provided tremendous impetus to the study of marine fungi. Chin.

Pectins are differed by three main structures: homogalacturonan (linear polymer), xylogalacturonan (branched by β-1,3-linked D-xylose), and rhamnogalacturonan. Bioinformatic characterization of genes encoding cell wall degrading enzymes in the Phytophthora parasitica genome. Additionally, fucoidans may have the mannose, xylose, galactose, rhamnose and uronic acid residues (Kim, 2011; Ermakova et al., 2015; Synytsya et al., 2015). tain obligate marine fungi, terrestrial fungi and those that can survive, or at least tolerate both environments to some degree. Cellulose was one of the most preferred carbon source for nine fungal strains among 18 marine-derived species (144 strains) in the study of Solis et al. (1979) stated that marine fungi can be categorized into two groups, namely the obligate marine fungi which are able to grow and sporulate exclusively in marine and estuarine habitat; and facultative marine fungi which originated from freshwater and terrestrial habitats but are able to grow and possibly sporulate in marine environment. Chem. The culturable mycobiota of Flabellia petiolata: first survey of marine fungi associated to a Mediterranean green alga. Biol. The facultative fungal endophyte Fusarium moniliforme isolated from decaying leaves of mangrove plants in the saline detritus-rich mud of a mangrove estuary on the west coast of India was a highly pectinolytic producer (Niturea et al., 2008). Front. Morgenstern, I., Powlowski, J., and Tsang, A. 3, 308–309. Thus, the marine laccases, peroxidases, and tannases could be of great interest in both biotechnology and ecology in the cases where a high concentration of salts are required, particularly in the extremely cold environments (Kamei et al., 2008; Raghukumar, 2008; Pang et al., 2011; Bonugli-Santos et al., 2010; Menezes et al., 2010; Feng et al., 2013; Sette and Santos, 2013). The higher levels of the expression of extracellular endoglucanase (EG), β-glucosidase (BGL), β-xylosidase (BXL), filter paper activity (FPase) under the 2-deoxy D-glucose (2-DG) treatment were exploited for evidence of the enzyme genes up-regulation (Mukherjee et al., 2016).
