Abstract

The correlation between the biosynthesis of the cell wall and the formation of streptomycin (SM) in Streptomyces griseus, influenced by a specific inhibitor of cell wall synthesis, was investigated. Penicillin, in subinhibitory concentrations (1 to 5 mug/ml), was added to cultures of S. griseus in different stages of its life cycle. The inhibitor decreased SM production, when young cultures were treated; however, there was an increase in SM formation when penicillin was added to older cultures. The explanation for these findings is discussed in detail.

摘要

研究了细胞壁合成的生物合成与灰色链霉菌中链霉素(SM)形成之间的相关性,该相关性受细胞壁合成的特异性抑制剂影响。将亚抑制浓度(1至5微克/毫升)的青霉素添加到处于其生命周期不同阶段的灰色链霉菌培养物中。当处理年轻培养物时,该抑制剂会降低SM的产量;然而,当将青霉素添加到较老的培养物中时,SM的形成会增加。对这些发现的解释进行了详细讨论。
