从污染的小麦全蚀病培养物中分离到一株链霉菌ｓｔ－１。该菌株的形态、培养特征、生理生化与已报道的近似种不同，是不吸水链霉菌中的一个新菌株。室内和田间试验表明，它所产生的抗生素对蔬菜灰霉病等病菌具有良好的防治效果。
Streptomyces st-1 was isolated from the contaminated wheat eclipse cultures. The morphology, culture characteristics, physiological and biochemical characteristics of the strain are different from the reported similar species, which is a new strain of Streptomyces hygroscopicus. Indoor and field trials show that the antibiotics it produces have good control effects on Botrytis cinerea and other germs.
