【摘要】 经筛选获得链霉菌代谢产物Ｓ－９２１、Ｓ－３１２，它们对菇类病害真菌的抗菌活力强，尤其对危害严重的木霉和链孢霉，最低抑菌浓度（ＭＩＣ）在２μｇ／ｍＬ以下，而对食用菌本身的毒性很低，ＭＩＣ在５００μｇ／ｍＬ以上，这些结果表明Ｓ－９２１和Ｓ－３１２具有良好的选择毒性。更多还原

【Abstract】 Through screening, we obtained two streptomyces metabolites, S-921 and S-312. They show strong antifungus activites (MIC<2μg/mL) against mushroom pathogenic fungis, especially Trichoderma and pink mold which harmed mushroom severely, and little toxicity (MIC>500μg/mL)to mushroom and mushroom pathogenic fungis.更多还原
