Abstract
Proansamycin B-M1 and protorifamycin I-M1 were isolated as minor compounds from fermentations of the protorifamycin I producing strain Nocardia mediterranei F 1/24, identified by means of chemical and spectroscopic methods and shown to be degradation products of the hypothetical proansamycin B postulated in part I of this series of papers and of protorifamycin I, respectively.
摘要
原安莎霉素B-M1和原利福霉素I-M1是从原利福霉素I产生菌地中海诺卡氏菌F 1/24的发酵产物中分离得到的次要化合物，通过化学和光谱方法进行鉴定，结果表明它们分别是本系列论文第一部分中假定的原安莎霉素B和原利福霉素I的降解产物。
