藏灵菇发酵乳中醋酸菌的分离纯化与鉴定

摘要

One Acetobacter strain, FJAT-13797, was isolated from Tibetan kefir. The image under scanning electronic microscope showed that the bacterium was rod-shaped with round ends, and presented in single or pairs without spores. The strain showed the bio-chemical properties of Acetobacter spp. The 16S rDNA sequence analysis indicated that the strain, FJAT-13797, belonged to Acetobacter orientalis.%从藏灵菇中分离出醋酸菌株FJAT-13797,利用形态学观察、生理生化和16S rDNA方法对其进行细菌学鉴定,菌体形态为圆端直杆,单个或成对,无芽孢,其生理生化特征与醋杆菌属(Acetobacter)基本一致.经16S rDNA基因序列同源性比较和系统发育分析,菌株FJAT-13797鉴定为东方醋酸菌(Acetobacter orientalis).
