摘要: |
从海洋沉积物中分离到一株放线菌YH91, 该菌株对金黄色葡萄球菌、大肠杆菌、以及镰刀菌具有较强的抑制作用。对其进行包括形态特征、培养特征、生理生化特性、细胞壁化学成分以及16SrDNA 序列的研究分析结果表明, 该放线菌是链霉菌属淀粉酶链霉菌(Streptomyces diastaticus)的一株亚种。 |

Identification of a marine actinomyce YH91 and its antimicrobial activity |
|
Abstract: |
An actinomycete strain YH91, isolated from marine sediment collected in Liaoning Province, north-east China, was determined by the polyphasic taxonomy method. The strain showed strong antagonism against Staphylococcus aureus, Escherichia coli, and Fusarium sp. According to its morphological and cultural characteristics, the physiological and biochemical properties and 16S rDNA sequence analysis, the strain was a new subspecies of Streptomyces diastaticus. |
