| Abstract: | Five yeast strains were isolated from soil and moss samples from the Livingston Island (Antarctica) and identified according
to morphological, cultural and physiological characteristics. All strains had an optimum growth temperature of 15°C; none
grew above 25°C. They assimilatedD-glucose.D-galactose, sucrose, cellobiose, trehalose, 2-keto-d-gluconate,D-xylose,d-ribose and melezitose. Four of them were nonfermentative, only one, which formed pseudomycelium fermented glucose, galactose,
trehalose. Two strains were identified as pinkred yeasts belonging to genusRhodotorula—R. minuta andR. mucilaginosa; two were related to the genusCryptococcus—C. albidus andC. laurentii, one wasCandida oleophila. |
