A Streptomyces sp. strain named C/33-6, previously isolated from soil, presented a strong and specific antagonistic effect against toxigenic fungi. This action was attributed to a proteinaceous compound (molecular weight estimated to be 14 kDa) present in the supernatant of the culture of strain C/33-6, which was sensitive to proteinases (elastase, pronase E, proteinase K) and prolongated heat treatment (100 degrees C, for 20 min). This compound showed non-chitinolytic fungicidal activity.
一种名为C/33 - 6的链霉菌菌株，先前从土壤中分离得到，对产毒真菌表现出强烈且特异的拮抗作用。这种作用归因于C/33 - 6菌株培养上清液中存在的一种蛋白质类化合物（估计分子量为14 kDa），该化合物对蛋白酶（弹性蛋白酶、链霉蛋白酶E、蛋白酶K）和长时间热处理（100℃，20分钟）敏感。这种化合物具有非几丁质分解性杀真菌活性。
