摘要
目的:从土壤中分离筛得一株对MRSA有明显抑菌活性的菌株。方法:分离得到一株放线菌NB0701,通过其生理生化反应,细胞壁化学组成、菌株细胞壁、糖型以及rRNA基因的序列进行了分析。结果:菌株细胞壁Ⅰ型,糖型C型,rRNA基因的序列分析其与Streptomyces parvus在16SrDNA中Blast比对相似率达99.9%。结论:定名为Streptomyces parvus subsp NB。
Objective：An actinomycetes strain was isolated from soil and its metabolites could inhibit the growth of MRSA.Method：NB0701 was isolated and identified its species through modality of the substrate mycelia and branched aerial mycelia,its cell wall,and genus analysis.Result：Its cell wall was type Ⅰand suger was type C the similar extent of NB070 and Streptomyces parvus.in 16SrDNA was nearly 99.9%.through rRNA gene sequence analysis and blast comparison.Conclusion：It was named as Streptomyces parvus subsp NB.
