| 摘 要： | 从新疆不同牧区采集工艺不同的干酪制品,对其中的乳酸菌进行分离纯化、生理生化性质试验和16S rRNA分析.结果表明,分离、纯化出的104株乳酸菌种,有82株为乳杆菌属(Lactobacillus),12株为肠球菌属(Enterococcus),10株为魏斯氏菌属(Weissella).利用16S rRNA序列同源分析和系统发育树分析对具有不同生理生化特性的代表菌株进行了分子鉴定,鉴定结果为TNM-2与干酪乳杆菌(Lactobacillus casei)、Y5-4与食窦魏斯氏菌(Weissella cibaria)、NS2-2与植物乳杆菌(Lactobacillus plantarum)的同源性达到100％,NM-2与瑞士乳杆菌(Lactobacillus helveticus)、Y1-1与马乳酒乳杆菌(Lactobacillus kefiranofaciens)、WG与耐久肠球菌(Enterococcus durans)的同源性达到99％.
