Abstract
As a result of microbiological research, information on the number and diversity of psychrotolerant yeast isolated from high-altitude and ground-based samples of atmospheric aerosol in the south of Western Siberia were obtained. In certain phenotypic and genomic characteristics, the yeast isolates were referred to the genera Saccharomyces , Candida , Sporidiobolus , Aureobasidium , Sporobolomyces , Cryptococcus , Rhodotorula , and other. Both saprophytic and pathogenic microorganisms were detected. The strain of yeasts of the genus Aureobasidium actively producing exopolysaccharides and melanin and being perspective for biotechnological developments were revealed.
