从西藏地区采集11份曲拉样品,从中分离出36株酵母菌.利用26S rDNA D1/D2区域序列分析对这些菌株进行了分类鉴定鉴定,可以将其分为8个属9个种.Debaryomyces hansenii是曲拉中的优势菌,其中Debaryomyces hansenii-Torulaspora delbrueckii和Debaryomyces hansenii-Candida zeylanoides是曲拉中酵母菌优势组合.曲拉中的酵母菌具有丰富的生物多样性,其差异性很大.%A total of 36 yeast strains were isolated from 11 traditional Qula samples in Tibet of China.The isolates were identified by the large-subunit (26S) rDNA gene D1 /D2 domain sequences analysis.These strains were grouped in 9 species belonging to 8 genera.The dominant species in Qula were Debaryomyces hansenii.Debaryomyces hansenii-Torulaspora delbrueckii and Debaryomyces hansenii-Candida zeylanoides were the predominant groups in Qula.There existed that yeasts of great biodiversity Qula in Tibet,but quite different from each other.
