简介
Twenty-five psychrophilic yeasts were isolated from the soil of Roopkund Lake, Himalayas, India. Two colony morphotypes were identified and representatives of ‘morphotype 1’ were identified as Cryptococcus gastricus. Representatives of ‘morphotype 2’, namely 3AT, 4A, 4B and Rup4B, showed similar phenotypic properties and are identical with respect to the nucleotide sequence of the ITS1-5.8S rRNA gene-ITS2 region and D1/D2 domain of the 26S rRNA gene. The sequence of D1/D2 domain of 3AT shows 97.6–98.8% similarity with Rhodotorula psychrophila CBS10440T, Rhodotorula glacialis CBS10437T and Rhodotorula psychrophenolica CBS10438T and in the neighbour-joining phylogenetic tree strains; 3AT, 4A, 4B and Rup4B form a cluster with Rhodotorula glacialis and Rhodotorula psychrophila. Strains 3AT, 4A, 4B and Rup4B also differ from their …
