Twenty-one psychrophilic yeast isolates related to the Camptobasidiaceae family in the Microbotryomycetes class were obtained from ice collected from cold environments worldwide. A new psychrophilic species from the recently described genus Cryolevonia, Cryolevania giraudoae is proposed to accommodate 18 isolates from Patagonia (Argentina) and Antarctica (holotype CRUB 2086T). In addition, a new psychrophilic species in the genus Camptobasidium is described as Camptobasidium gelus sp. nov… Expand
Greenland and Svalbard glaciers host unknown basidiomycetes: the yeast Camptobasidium arcticum sp. nov. and the dimorphic Psychromyces glacialis gen. and sp. nov.
TLDR
Based on ribosomal genes, Camptobasidium arcticum and Psychromyces glacialis are related, phylogenetically most closely related to the genera Glaciozyma and Cryolevonia. Expand
Metabolic activity and bioweathering properties of yeasts isolated from different supraglacial environments of Antarctica and Himalaya
TLDR
The ability of yeasts to use diverse organic compounds prevalent on the glacier surface points to their ecological significance in the decomposition of organic matter, cycling of nutrients, and in the weathering of minerals in supraglacial environments. Expand

Cryolevonia gen. nov. and Cryolevonia schafbergensis sp. nov., a cryophilic yeast from ancient permafrost and melted sea ice.
TLDR
Phylogenetic analyses employing combined sequences of the D1/D2 domain and ITS region indicated that the two new isolates belong to the family Camptobasidiaceae of the class Microbotryomycetes but are distantly related to any of the currently recognized species and genera. Expand

The description of Glaciozyma genus and the re-classification of L. antarcticum reduce the polyphyletic nature of the genus Leucosporidium. Expand
Sex in the cold: taxonomic reorganization of psychrotolerant yeasts in the order Leucosporidiales.
TLDR
The phenotypic, genetic and sexual characteristics of three species of Leucosporidiales are studied to clarify the evolutionary relationship among these closely related taxa and it becomes clear that these yeasts can interbreed. Expand

TLDR
Among yeast strains expressing extracellular enzymatic activity, higher proteolytic and lipolytic activities were obtained at 4 degrees C than at 20 degrees C, and Cryptococcus sp. Expand
Psychrophilic yeasts from worldwide glacial habitats: diversity, adaptation strategies and biotechnological potential.
TLDR
An overview of the distribution and adaptation strategies of psychrophilic yeasts worldwide and attention is focused on their biotechnological potential, especially on their exploitation as a source of cold-active enzymes and for bioremediation purposes. Expand
Yeasts from glacial ice of Patagonian Andes, Argentina.
TLDR
Cold-adapted yeast isolates were able to hydrolyze natural compounds at low temperatures, suggesting a significant ecological role of these organisms as organic matter decomposers and nutrient cyclers. Expand
Metabarcoding analysis of the fungal biodiversity associated with Castaño Overa Glacier – Mount Tronador, Patagonia, Argentina
TLDR
This is the first report of fungal diversity in an extreme glacial environment of Patagonian Argentina using amplicon sequencing and showed high biodiversity in glacial environments and allowed the detection of hitherto unknown taxa for Patagonia. Expand
Yeasts of the White Sea intertidal zone and description of Glaciozyma litorale sp. nov.
TLDR
The intertidal yeast communities inhabiting various environments in the territories of the White Sea Biological Station “Kartesh” and the N.A. Pertsov White Sea biological station were studied and a new basidiomycetous yeast species was described, which was described in this work as Glaciozyma litorale sp. Expand
CAMPTOBASIDIUM HYDROPHILUM AND ITS ANAMORPH, CRUCELLA SUBTILIS: A NEW HETEROBASIDIOMYCETE FROM STREAMS
TLDR
Camptobasidium hydrophilum with an anamorph, Crucella subtilis anam, isolated from decaying leaves collected in a stream in Alabama, and when grown in dual culture, hyphae of C. hydrophILum make contact with and coil around the hyphai of the other fungi suggesting that the species can be parasitic.

Rhodotorula psychrophila sp. nov., Rhodotorula psychrophenolica sp. nov. and Rhodotorula glacialis sp. nov., novel psychrophilic basidiomycetous yeast species isolated from alpine environments.
TLDR
Three novel psychrophilic species of the genus Rhodotorula are described and sequence analyses of the 26S rDNA D1/D2 regions indicated that the novel species are phylogenetically related and belong to a clade that includes other psychrophobic yeasts. Expand
