从厦门海区潮间带江蓠植物中分离到一株链霉菌 ,其发酵液经体外MTT法和BIA法 (生化诱导法 )测定 ,表明具有很高的抑制肿瘤活性 ,该菌的生物量和抑癌活性与海水基质有关 .对分类学特征的研究显示 ,该菌不同于目前已知的其他放线菌种类 ,将该菌定为公牛链霉菌海洋变种 (Streptomycestauricusvar.marinus) .
Streptomyces was isolated from the tidal flat Phragmites australis in Xiamen sea area. The fermentation broth was determined by in vitro MTT assay and BIA method (biochemical induction method), indicating that it has high inhibitory activity on tumor. Carcinogenicity is related to seawater matrix.Studies on the taxonomic characteristics show that this bacterium is different from other actinomycete species known to date and this bacterium is designated as Streptomycestauricus var. Marinus.
