一株牛源副干酪乳杆菌的分离与鉴定

Isolation and Identification of a Strain of Lactobacillus casei from Bovine

为了分离有研究价值的益生菌,从牛肠道中分离到1株疑似乳酸菌,通过对参考菌株的16S r RNA基因序列的归纳分析,证实存在种间特异性可变区,最终确定为副干酪乳杆菌,分离菌作为一种益生菌在饲料添加剂方面存在重要研究价值。

One strain of Lactobacillus was isolated from bovine intestine in order to separate the valuable probiotics. Followed by 16S rRNA gene sequences analysis, the existence of species specific variable region was confirmed. This strain was eventually identified as Lactobacillus paracasei, which may have important research and application in the feed additive industry.
