The Untapped Potential of Marine Fungi: A Dive into the World of Marine Mycology

Advertisment

DNA sampling is revolutionizing our understanding of marine ecosystems by revealing the thriving presence of fungi in these environments. This challenges the traditional view that considers fungi purely as land-dwelling organisms. These marine-adapted fungi, including lichens, are prevalent in coastal areas and have been largely overlooked by mainstream mycologists. However, this underexplored field is now garnering attention due to the potential role of marine fungi in addressing pressing global issues like antibiotic resistance and plastic pollution.

Marine Fungi: A Fresh Perspective

Contrary to common belief, fungi aren't just terrestrial organisms. DNA sampling research has unveiled a new diversity of Dinomycetaceae, a family of fungal parasites of marine dinoflagellates. This discovery underscores the richness of marine fungi diversity and their potential role in marine ecosystems. It also presents a new perspective on fungi, challenging the conventional idea that they only thrive on land.

The Fragility and Significance of Marine Fungi DNA

While marine fungi are emerging as potential game-changers in marine ecosystems and global problems, their DNA and RNA stability remains a critical consideration. A recent study found that over 90% of DNA and up to 99% of RNA for all microalgal species were degraded within 60 days at 4 °C. This rapid degradation has significant implications for the data interpretation of metabarcoding surveys, especially in the detection of resting cysts.

Exploring the Medicinal Potential of Marine Fungi

Marine-derived fungi of the genus Trichoderma are currently a hotspot of research for pharmaceuticals and agrochemicals. Recent studies have identified 445 new metabolites, including terpenes, steroids, polyketides, peptides, and alkaloids, from these fungi. These metabolites exhibit various biological activities, suggesting the potential of marine fungi in the development of new drugs and agrochemicals.

Unraveling the Role of Marine Fungi in Biogeochemical Cycles

The ocean microbiome plays a crucial role in Earth's biogeochemical cycles, and marine fungi are a part of this intricate web. A dataset of 76 microbial metagenomes collected in 11 vertical profiles during the Malaspina Expedition has shed light on the functional and taxonomic connectivity between the photic and bathypelagic tropical and sub-tropical ocean. This research aims to enhance our understanding of the ocean microbiome and the role of marine fungi in it.

Impact of Storage Methods on Marine Fungi

Understanding the impact of different soil storage methods on the microbial community composition is critical for marine fungi studies. Comparative studies of refrigeration, freezing, and air drying storage methods have shown that soil microbial communities are relatively robust, but some significant differences in beta diversity emerge in long-term experiments. This underlines the need for careful considerations when storing marine fungi samples for research.

In conclusion, the discovery and study of marine fungi have given rise to high hopes for their beneficial impact on global problems. While many aspects of marine fungi remain shrouded in mystery, ongoing research continues to reveal their potential in various fields, from addressing antibiotic resistance and plastic pollution to the development of new pharmaceuticals and gaining a deeper understanding of marine ecosystems.
