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.
