摘要
对一株从海南土壤样品中分离得到的放线菌T151进行初步鉴定,分析其代谢产物的抑菌活性。通过扫描电镜形态观察和16S rDNA序列分析,初步鉴定该菌株为链霉菌属新种。抑菌活性分析表明,该菌发酵液对大肠杆菌、枯草芽孢杆菌和根霉均有抑制作用;发酵液的稳定性分析表明活性成分在100℃处理30 min,pH5-11仍保留很强的抑菌活性。
Actinomyces T151, isolated from soil in Hainan province, was identified and screened for antimicrobial activity. TIS1 was designated as a new strain of Streptornyces according to the observation of SEM morpholiogical and analysis of 16S rDNA sequence. Its fermentation broth exhibited inhibition effect against Escherichia coli, Bacillus subtilis and Rhizopus. The fermentation broth was still owned high antimicrobial activity under 100℃ for 30 min or pHS-11.
