摘　　要：从青海的互助、民和、门源等10个州县收集土样分离得到98株酵母菌,利用26S rDNA D1/D2区域序列分析并结合形态学和生理生化特性对这些菌株进行了分类学研究,探讨了青海东部土壤中酵母的物种多样性及其分布。共鉴定出10属13种(其中有两个疑似新种),其中Ga-lactomyces geotrichum和Rhodotorula mucilaginosa为该地的优势种。98 yeast strains were isolated from soil samples collected from 10 counties in the east part of Qinghai Province. These strains were identified mainly based on the 26S rDNA D1/D2 domain sequence analysis and morphological and physiological characterization. Diversity and distribution of the yeast species in the soil samples were analysed. Among them, 13 species belonging to 10 genera were recognized （two strains might represent two new species）. The dominant species identified were Galactomyces geotrichum and Rhodotorula mucilaginosa.
