| 摘 要： | 为从广西北部湾的泥样和植物中分离海洋放线菌,筛选具有抑菌活性的菌株,分离活性化合物。研究采用普通稀释法分离菌株,对发酵产物进行抑菌活性测试,利用活性追踪分离活性化合物,并通过波谱方法确定化合物结构。结果表明从6个海泥样品和3个植物样品中共分离73株放线菌,筛选得到具有抑香蕉枯萎病和金黄色葡萄球菌活性的菌株7株,并从其中的1株链霉菌 Streptomyces sp.MDCW-126的次级代谢产物中分离鉴定了星形孢菌素。从广西北部湾分离的药用活性菌株资源具有开发和深入研究价值。

| Abstract: | To isolate marine actinomycetes from Beibu Gulf nearby Guangxi soil and plants,and to screen antibiotic actinomycete strains,and to isolate active compounds.The isolation of actinomycetes was performed by normal methods,the screening of active fermentation products was preceded by antibacterial assays,the isolation of compounds were performed by bioassay-guided method,the structure of compound was elucidated through the spectroscopic analysis.The results showed that 73 actinomycetes strains were isolated from Beibu Gulf nearby Guangxi soil and plants,7 of which showed antimicrobial activities against Fusarium oxysporum f.sp. cubense , Staphylococcus aureus .And staurosporin was identified from the secondary metabolites of Streptomyces sp.MDCW-126.Actinomycetes from Beibu Gulf nearby Guangxi are potential resources for active strains and need further study. |
