1株蜡样芽孢杆菌的分离鉴定及其生物学功能研究

Isolation and identification of a strain of Bacillus cereus and study on its biological function

试验从新鲜猪场粪便中筛选获得1株蜡样芽孢杆菌疑似菌株,进行16SrDNA分析、形态学鉴定、自动化微生物鉴定与药敏检测系统综合分析。结果显示,蜡样芽孢杆菌疑似菌株为蜡样芽孢杆菌,命名为W21-B5,对其生物学功能进行研究,发现其具有较强的产蛋白酶和产淀粉酶功能。

In the experiment,a suspected Bacillus cereus strain was screened from the feces of fresh pig farms,and the 16S rDNA analysis,morphological identification,automated microbial identification and comprehensive analysis of the drug sensitivity detection system were carried out.The results showed that the suspected strain of Bacillus cereus was Bacillus cereus,which was named W21-B5,and it was found that it has strong functions of producing protease and amylase by biological function study.
