广谱高效抑菌物质产生菌的筛选及鉴定

Identification and Screening of Broad-spectrum Antibiotics-producing Strains

摘要:

本实验从营养丰富的土壤中经初筛分离到60株具有抑菌活性的细菌, 在此基础上通过琼脂打孔扩散法进行复筛, 获得一株具有广谱抑菌活性的菌株, 经理化指标及16S rDNA序列测定和同源分析鉴定为侧孢短芽孢杆菌, 命名为S62-9.

Abstract:

60 strains which have antimicrobial activity had been isolated from nutritious soil in China in the study. We have further selected 1 strain which product broad-spectrum antibiotics using agar well-diffusion method. The strain was identified Brevibacillus laterosporus after physiological biochemical characteristic experiments, sequencing of 16S rDNA and cluster analysis, named S62-9.
