It has been shown previously that aerobic actinomycetes can be separated into four main groups on the basis of their cell wall composition. Six representatives of aerobic actinomycetes (Nocardia asteroides and Micropolyspora brevicatena, cell wall type IV; N. madurae, Microbispora rosea, cell wall type III; Actinoplanes sp., cell wall type II; Streptomyces griseus, cell wall type I) were subjected to selecting agents which permitted the isolation of stable variants morphologically different from the parent strain. Whole cell analyses of 134 substrains from the six parents revealed no significant change in the isomeric form of diaminopimelic acid or in sugar constituents. Analyses of cell wall preparations from 52 of these did not reveal any change in the diagnostic constituents of their murein or polysaccharides.
先前已经表明，需氧放线菌可根据其细胞壁组成分为四个主要类群。选取了六种需氧放线菌（星形诺卡氏菌和短链小多孢菌，细胞壁类型IV；马杜拉诺卡氏菌、玫瑰小双孢菌，细胞壁类型III；游动放线菌属，细胞壁类型II；灰色链霉菌，细胞壁类型I），使其接触能够分离出形态上不同于亲本菌株的稳定变体的选择剂。对来自这六个亲本的134个亚菌株进行全细胞分析，结果显示二氨基庚二酸的异构形式或糖类成分没有显著变化。对其中52个菌株的细胞壁制剂进行分析，结果未发现其胞壁质或多糖的诊断成分有任何变化。
