摘　　要：从我国海南岛土壤中分离到一株链霉菌B-7,产生多组份的链丝菌素(从1～6),其发酵液对大白菜软腐病有稳定的防治效果,该菌株在形态培养特征和生理生化特性上与淡紫灰链霉菌Streptomyces Lavendulae相似,但又有一定的差别,命名为淡紫灰链霉菌海南变种(Streptomyces lavendulae var.hainanensis n.var.)。A strain B-7 of Streptomyces sp. was isolated from soil samples collected in Hainan,China. It was found to produce different components of streptoth-ricin antibiotics which are effective in preventing and controlling the Chinese cabbage diseases caused by Erowinia aroideas. The sporophores of the strain B-7 are spiral, 1-4 turns. The surface of spores are smooth. The aerial mycelium is white to reddish gray with lavender shade. The substrate mycelium is colorless to faint yellow. The chemical composition of cell wall belongs to type I. The strain is similar to Streptomyees lavendulae ISP 5069 (IMRU-3440), but shows somewhat different cultural characteristics and utilization of carbon sources.Therefore it has been named St-reptomyces lavendulae var. hainanensis n. var.
