“…However, due to ‘great plate anomaly’ and other biases, the densities of culturable fungi in the ocean are several orders of magnitude lower than that of fungi detected either by direct detection or molecular techniques. The culturable fungal abundance (CFU L −1 ) was found to be three orders of magnitude [ 78 , 79 ], while the abundance (gene copies L −1 ) based on the qPCR method was five to eight orders of magnitude [ 18 , 19 , 80 , 81 ]. Fungal enumeration by culturing has been criticized because a colony can arise out of single spores, groups of spores, single cells, or mycelial fragments.…”

Fungi are considered terrestrial and oceans are a “fungal desert”. However, with the considerable progress made over past decades, fungi have emerged as morphologically, phylogenetically, and functionally diverse components of the marine water column. Although their communities are influenced by a plethora of environmental factors, the most influential include salinity, temperature, nutrients, and dissolved oxygen, suggesting that fungi respond to local environmental gradients. The biomass carbon of planktonic fungi exhibits spatiotemporal dynamics and can reach up to 1 μg CL−1 of seawater, rivaling bacteria on some occasions, which suggests their active and important role in the water column. In the nutrient-rich coastal water column, there is increasing evidence for their contribution to biogeochemical cycling and food web dynamics on account of their saprotrophic, parasitic, hyper-parasitic, and pathogenic attributes. Conversely, relatively little is known about their function in the open-ocean water column. Interestingly, methodological advances in sequencing and omics approach, the standardization of sequence data analysis tools, and integration of data through network analyses are enhancing our current understanding of the ecological roles of these multifarious and enigmatic members of the marine water column. This review summarizes the current knowledge of the diversity and abundance of planktonic fungi in the world’s oceans and provides an integrated and holistic view of their ecological roles.

“…Marine fungi are a diverse group of opportunistic and obligate organisms isolated from marine environments [ 1 , 2 ]. In recent years interest in the secondary metabolites and bio-active compounds produced by some of these fungi has grown [ 2 , 3 ] and they are increasingly included in ecological studies of marine environments [ 1 , 2 , 4 ]. Recent initiatives to develop and exploit marine resources have led to an increase in the isolation of these fungi and screening for novel compounds.…”

BackgroundMarine fungi are a diverse group of opportunistic and obligate organisms isolated from marine environments. These fungi are now often included in screens for novel metabolites, while less attention has been given to their production of hydrolytic enzymes. Most enzymes derived from marine microorganisms have been obtained from marine bacteria. The enzymes produced by marine fungi may have different properties than those derived from bacteria or from terrestrial fungi. Here we assess the growth of six filamentous marine fungi on a wide range of polymeric substrates as an indication of their general capacity to produce hydrolytic enzymes.ResultsCalcarisporium sp. KF525, Tritirachium sp. LF562, Bartalinia robillardoides LF550, Penicillium pinophilum LF458, Scopulariopsis brevicaulis LF580 and Pestalotiopsis sp. KF079 all grew on both casein and gelatin as N-source, indicating secretion of proteases. All species also grew on starch, laminarin, xylan, pectin and oil, indicating production of amylases, glucanases, xylanases, pectinases and lipases. Growth on cellulose occurred but was weaker than on xylan. All strains also grew to some extent on sulphated arabinogalactan, although only LF562 could utilise arabinose. Four strains grew on the sulphated ulvans, whereas only KF525 grew on agar or carrageenan. KF525 and LF562 showed limited growth on alginate. Although fucose was used as carbon source by several species, fucoidan did not support biomass production.ConclusionsMarine fungi could be excellent sources of a wide range of hydrolytic enzymes, including those able to hydrolyse various seaweed polymers. Although the native hosts may secrete only small amounts of these enzymes, the genes may provide a rich source of novel enzymes.Electronic supplementary materialThe online version of this article (doi:10.1186/s12896-016-0233-5) contains supplementary material, which is available to authorized users.

“…Obligate marinederived fungi are fungi that grow and sporulate exclusively in estuarine or marine habitats. Facultative marine-derived fungi are fungi from freshwater or terrestrial habitats are able to grow, and may also sporulate, in the marine environment (Velmurugan et al, 2013). Marine derived fungi are heterotrophic microorganisms that can be found in a variety of substrates as saprophytic and parasitic (Raghukumar, 1990).…”

Marine organisms are a source of natural products and produce compounds with a molecular structure that is unique and useful. Thousands of new compounds have biological activitity for anticancer, antiviral, and antimicrobial. This compounds isolated from various marine organism, including from marine-derived fungi. Investigation of chemical compounds from marine-derived fungi isolated from sponge has increased steadily, indicating the important role of marine-derived fungi in the discovery of drug compounds. The sponge has produced various kinds of fungi, which have reported to provide a variety of pharmacologically active metabolites and structurally diverse. Study literature showed that many fungal genera isolated from the marine sponge dominated the genus Acremonium, Aspergillus, Penicillium, Phoma, and Fusarium. The high proportion of genera and new compounds showed that the fungi isolated from the sponge could develop.
