一株芽孢杆菌的分离和鉴定

Isolation and Identification of a Bacillus sp. Starin

摘要:

从中国农业科学院北京畜牧兽医研究所鸡舍附近土壤中分离到一株芽孢杆菌P-25, 并进行了分子鉴定。通过形态鉴定、革兰氏染色、生理生化测定、16S rRNA序列分析和系统发育树构建, 确定该菌株为蜡状芽孢杆菌(Bacillus cereus), 其16S rRNA GenBank登录号为GU271135。

关键词:芽孢杆菌, 16S rRNA, 鉴定

Abstract:

A Bacillus sp. strain P-25 was isolated from soil nearby the henhouse of Institute of Animal Sciences, Chinese Academy of Agricultural Sciences. This bacterium was identified as Bacillus cereus by analyses of its morphological and biochemical properties and 16S rRNA sequence.
