“…Fungi isolated from deep seas were first reported nearly 50 years ago (Roth et al 1964), then a great number of fungi including some novel species have been published by both conventional culture-dependent (Raghukumar et al 2004; Gadanho and Sampaio 2005; Damare et al 2006; Nagahama et al 2006; Le Calvez et al 2009; Singh et al 2010) and culture-independent methods (Lai et al 2007; Le Calvez et al 2009; Nagano et al 2010). Le Calvez et al (2009) reported striking differences in their comparison of deep-sea fungal diversity assessed by culture-dependent and culture-independent methods.…”

Our planet is dominant with cold environments that harbour enormously diverse cold-adapted fungi comprising representatives of all phyla. Investigation based on culture-dependent and independent methods has demonstrated that cold-adapted fungi are cosmopolitan and occur in diverse habitants and substrates. They live as saprobes, symbionts, plant and animal parasites and pathogens to perform crucial functions in different ecosystems. Pseudogymnoascus destructans caused bat white-nose syndrome and Ophiocordyceps sinensis as Chinese medicine are the representative species that have significantly ecological and economic significance. Adaptation to cold niches has made this group of fungi a fascinating resource for the discovery of novel enzymes and secondary metabolites for biotechnological and pharmaceutical uses. This review provides the current understanding of living strategy and ecological functions of cold-adapted fungi, with particular emphasis on how those fungi overcome the extreme low temperature and perform their ecological function.

“…Other OTUs (otu3, 7 and 11) belonging to the Ascomyta phylum were also present in the center and top, but only otu11 could be precisely assigned (97% similarity) to sequences from spring water (Oliveira et al, 2013). In the Canyon after 210 days, the most abundant fungal OTU was an Ascomyta that was similar to sequences found in the sea and mangrove sediments with 100% similarity, and another OTU that was 99% similar to a sequence from methane hydrate-bearing deep-sea marine sediments (Lai et al, 2007).…”

Wood falls on the ocean floor form chemosynthetic ecosystems that remain poorly studied compared with features such as hydrothermal vents or whale falls. In particular, the microbes forming the base of this unique ecosystem are not well characterized and the ecology of communities is not known. Here we use wood as a model to study microorganisms that establish and maintain a chemosynthetic ecosystem. We conducted both aquaria and in situ deep-sea experiments to test how different environmental constraints structure the assembly of bacterial, archaeal and fungal communities. We also measured changes in wood lipid concentrations and monitored sulfide production as a way to detect potential microbial activity. We show that wood falls are dynamic ecosystems with high spatial and temporal community turnover, and that the patterns of microbial colonization change depending on the scale of observation. The most illustrative example was the difference observed between pine and oak wood community dynamics. In pine, communities changed spatially, with strong differences in community composition between wood microhabitats, whereas in oak, communities changed more significantly with time of incubation. Changes in community assembly were reflected by changes in phylogenetic diversity that could be interpreted as shifts between assemblies ruled by species sorting to assemblies structured by competitive exclusion. These ecological interactions followed the dynamics of the potential microbial metabolisms accompanying wood degradation in the sea. Our work showed that wood is a good model for creating and manipulating chemosynthetic ecosystems in the laboratory, and attracting not only typical chemosynthetic microbes but also emblematic macrofaunal species.

“…Strains belonging to the genera Rhodosporidium, Rhodotorula, and Candida have been frequently found in deep-sea environments, using culture-independent methods. On the contrary, species of the genera Cryptococcus, Pichia, and Trichosporon seem to be detected more frequently using culture-independent methods than by using culture-dependent methods (Bass et al 2007;Lai et al 2007;Nagano et al 2010;Singh et al 2010). The basidiomycetous yeast Cryptococcus curvatus was found to be the dominant eukaryotic microorganisms in oxygen-depleted sediments from deep-sea methane seeps at the Kuroshima Knoll (Takishita et al 2006).…”

“…The advantages of using molecular methods are mainly the requirement of only a small amount of samples and the detection of difficult-to-culture or unculturable species, including rare species. Yeast species which have not been reported by culture-dependent methods have been detected by culture-independent methods from deep-sea environments (Bass et al 2007;Lai et al 2007;Le Calvez et al 2009;Nagano et al 2010;Singh et al 2010Singh et al , 2011Nagahama et al 2011).

“…Strains of the genus Malassezia have never been isolated by culture-dependent methods but are frequently reported from culture-independent methods (Bass et al 2007;Lai et al 2007;Singh et al 2010Singh et al , 2011Nagahama et al 2011). As Malassezia species are known to be difficult to grow under laboratory conditions, a diversity study based on culture-dependent methods may often miss these organisms.…”

Cold-Adapted Yeasts

Deep sea, the world's largest cold environment, is an environment of extreme conditions, such as high hydrostatic pressure and low nutrient availability, and has an average water temperature between -1 and 4°C in most areas of deep sea. Living organisms in deep sea are considered to be adapted to cold environments. Yeast diversity commonly found in deep sea is represented by Rhodosporidium spp., Rhodotorula spp., Candida spp., Cryptococcus spp., Pichia spp., Sporobolomyces spp., and Trichosporon spp. This representation of yeasts is similar to yeasts found in other cold environments. Only psychrotolerant yeasts have been reported from deep-sea environments to date. However, the majority of yeasts isolated from deep-sea environments show better growth in deep-sea simulated conditions, such as 3°C/40 MPa, than yeasts isolated from terrestrial environments. In comparison with prokaryotic microorganisms, yeasts in deep-sea environments are relatively underexplored, with few studies carried out on their physiology. Although the true yeast diversity and their ecology in deep-sea environments remains unclear, the intention of this chapter is to discuss current knowledge on deep-sea yeast diversity and their physiological characteristics and adaptation mechanisms to cold and high pressure in the model yeast Saccharomyces cerevisiae.
