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16SrDNA序列测定和同源分析鉴定为侧孢短芽孢杆菌,命名为S62-9.60 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.
