中文摘要：

对分离自酸马奶酒中的一株产抑菌物质的酵母菌HJ-5进行分离鉴定及系统发育分析，以更准确地判定其属种。采用细胞形态、生理学特性及其26SrDNA D1／D2序列分析，结果表明，菌株HJ-5的细胞形态及生理学特性符合酵母属特征。通过26SrDNAD1／D2序列进行系统发育分析，被鉴定为Saccharomyces cerevisiae。

英文摘要：

For researching the genus and strains of the antibacterial ability yeast which was isolated from koumiss, were isolated, identified and molecular biologically. The results indicated that the morphologically, physiologically of yeast H J-5 were same with Saccharomyces, we also was identified molecular biologically by comparing with 26S rDNA D1/D2 sequence.h was Suecharomyces cerevisiae.
