Cystobasidium alpinum sp. nov. and Rhodosporidiobolus oreadorum sp. nov. from European cold environments and Arctic region
Over 80% of the Earth’s environments are permanently or periodically exposed to temperatures below 5 ◦C. Cold habitats harbour a wide diversity of psychrophilic and psychrotolerant yeasts. During ecological studies of yeast communities carried out in cold ecosystem in the Italian Alps, Svalbard (Nor...
