Identification of a marine actinomyce YH91 and its antimicrobial activity
海洋放线菌91分类鉴定及其抑菌活性的研究

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.
