“…Several taxa isolated in this study were only obtained from plates incubated at 24 C, a considerably higher condition than the sampling site ranging 3.4 C-7.1 C. As previously pointed out (Burgaud et al, 2009), these isolates might represent propagules of non-autochthonous marine fungi that sank in the deep-sea after being transported by marine currents and survived dormant in the new habitat. However, a higher optimal growth temperature in axenic culture compared to the environment of isolation was also observed for fungi isolated from Antarctic water (Martorell et al, 2020). Further studies on our isolates optimal conditions for growth might help to define autochthonous marine and deep-sea species, although the requirements expressed in axenic culture may differ to what preferred in their original habitat.…”

“…Mucoromycota were rarely detected in the marine environment using culture‐based and metagenomic studied (Höller et al ., 2000) and only once in the deep‐sea (Xu et al ., 2019). Reports from cold habitats showed their preference to grow on Antarctic land associated to plant roots rather than on marine sediments (Wentzel et al ., 2019) and in association with Antarctic macroalgae (Martorell et al ., 2020). In the latter study, Mucoromycota isolates were highlighted as the only strains to be preferentially growing at low temperature in axenic culture.…”

Fungi populate deep Oceans in extreme habitats characterized by high hydrostatic pressure, low temperature and absence of sunlight. Marine fungi are potential major contributors to biogeochemical events, critical for marine communities and food web equilibrium under climate change conditions and a valuable source of novel extremozymes and small molecules. Despite their ecophysiological and biotechnological relevance, fungal deep-sea biodiversity has not yet been thoroughly characterized. In this study, we describe the culturable mycobiota associated with the deepest margin of the European Western Continental Shelf: sediments sampled at the Porcupine Bank and deep-water corals and sponges sampled in the Whittard Canyon. Eighty-seven strains were isolated, belonging to 43 taxa and mainly Ascomycota. Ten species and four genera were detected for the first time in the marine environment and a possible new species of Arachnomyces was isolated from sediments. The genera Cladosporium and Penicillium were the most frequent and detected on both substrates, followed by Candida and Emericellopsis. Our results showed two different fungal communities: sediment-associated taxa which were predominantly saprotrophic and animalassociated taxa which were predominantly symbiotic. This survey supports selective fungal biodiversity in the deep North Atlantic, encouraging further mycological studies on cold water coral gardens, often overexploited marine habitats.

“…Most of the research on Antarctic fungi focused on the assemblages associated with benthic macroalgae of the South Shetland Islands (Antarctic Peninsula) [ 54 , 64 , 66 , 67 , 68 , 69 , 70 ]. In particular, the macroalgae Adenocystis utricularis , Desmarestia anceps and Palmaria decipiens host a rich fungal diversity, including genera like Pseudogymnoascus , Antarctomyces , Oidiodendron , Penicillium , Phaeosphaeria , Cryptococcus , Leucosporidium , Metschnikowia , and Rhodotorula .…”

The Antarctic Ocean is one of the most remote and inaccessible environments on our planet and hosts potentially high biodiversity, being largely unexplored and undescribed. Fungi have key functions and unique physiological and morphological adaptations even in extreme conditions, from shallow habitats to deep-sea sediments. Here, we summarized information on diversity, the ecological role, and biotechnological potential of marine fungi in the coldest biome on Earth. This review also discloses the importance of boosting research on Antarctic fungi as hidden treasures of biodiversity and bioactive molecules to better understand their role in marine ecosystem functioning and their applications in different biotechnological fields.

“…The genus Pseudogymnoascus as a kind of psychrophilic pathogenic fungi is widely distributed in Antarctica (Rosa et al, 2020;Santos et al, 2020;Martorell et al, 2021). Pseudogymnoascus can be one of the antagonistic fungi against potato scab pathogens from potato field soils, which could be used as potential agents to control potato scab disease (Tagawa et al, 2010).…”

“…It has been proved that Antarctic microorganisms, especially fungi, have the potential capacity to produce novel secondary metabolites to adapt to the harsh environments (Kwon et al, 2017;Rusman et al, 2018;Yu et al, 2019;. Pseudogymnoascus are known as a kind of psychrophilic pathogenic fungi with ubiquitous distribution in Antarctica (Rosa et al, 2020;Santos et al, 2020;Martorell et al, 2021). These fungal strains have been proved to have the abilities to produce cold-adapted enzymes to adapt severe cold Antarctic environment (Loperena et al, 2012;Poveda et al, 2018).…”

The fungal strains Pseudogymnoascus are a kind of psychrophilic pathogenic fungi that are ubiquitously distributed in Antarctica, while the studies of their secondary metabolites are infrequent. Systematic research of the metabolites of the fungus Pseudogymnoascus sp. HSX2#-11 led to the isolation of six new tremulane sesquiterpenoids pseudotremulanes A–F (1–6), combined with one known analog 11,12-epoxy-12β-hydroxy-1-tremulen-5-one (7), and five known steroids (8–12). The absolute configurations of the new compounds (1–6) were elucidated by their ECD spectra and ECD calculations. Compounds 1–7 were proved to be isomeride structures with the same chemical formula. Compounds 1/2, 3/4, 1/4, and 2/3 were identified as four pairs of epimerides at the locations of C-3, C-3, C-9, and C-9, respectively. Compounds 8 and 9 exhibited cytotoxic activities against human breast cancer (MDA-MB-231), colorectal cancer (HCT116), and hepatoma (HepG2) cell lines. Compounds 9 and 10 also showed antibacterial activities against marine fouling bacteria Aeromonas salmonicida. This is the first time to find terpenoids and steroids in the fungal genus Pseudogymnoascus.
