Abstract

This study focused on isolation and identification of wild yeasts from soils in fields near mountains and elucidation of its yeast distribution. Several kinds of yeasts were isolated from various soils of Daejeon metropolitan city and Chungcheongnam-do in Korea and identified by BLAST search of nucleotide sequences of internal transcribed spacer (ITS) region including 5.8S rRNA and D1/D2 region of 26S rDNA. Ninety-seven strains of 20 species from 61 soil samples were isolated, of which Cryptococcus podzolicus (11 strains), Debaryomyces hansenii (6 strains), and Trichosporon asahii (6 strains) were dominant species.
