The cell walls and peptidoglycans of two mutant strains, Streptomyces chrysomallus var. carotenoides and Streptomyces chrysomallus var. macrotetrolidi, were studied. The strains are organisms producing carotenes and antibiotics of the macrotetrolide group. By the qualitative composition of the peptidoglycans the mutants belong to Streptomyces and are similar. Their glycan portion consists of equimolar quantities of N-acetyl glucosamine and muramic acid. The peptide subunit is presented by glutamic acid, L, L-diaminopimelic acid, glycine and alanine. The molar ratio of alanine is 1.2-1.3. The mutant strains differ in the content of carbohydrates, total phosphorus and phosphorus belonging to teichoic acids. Teichoic acids of the cell walls of the both strains are of the ribitolhosphate nature. The cell walls of the mutants contain polysaccharides differing from teichoic acids and consisting of glucose, galactose, arabinose and fucose. The influence of the cell wall composition of the mutant strains on their morphology and metabolism and comparison of the data relative to the mutant strains with those relative to the starting strain are discussed.
对两种突变菌株，即类胡萝卜素链霉菌变种和大元四内酯链霉菌变种的细胞壁和肽聚糖进行了研究。这些菌株是产生胡萝卜素和大元四内酯类抗生素的生物体。从肽聚糖的定性组成来看，这些突变体属于链霉菌属且相似。它们的聚糖部分由等摩尔量的N - 乙酰葡糖胺和胞壁酸组成。肽亚基由谷氨酸、L，L - 二氨基庚二酸、甘氨酸和丙氨酸组成。丙氨酸的摩尔比为1.2 - 1.3。突变菌株在碳水化合物、总磷以及属于磷壁酸的磷含量方面存在差异。两种菌株细胞壁的磷壁酸均具有磷酸核糖醇的性质。突变体的细胞壁含有不同于磷壁酸且由葡萄糖、半乳糖、阿拉伯糖和岩藻糖组成的多糖。讨论了突变菌株细胞壁组成对其形态和代谢的影响，以及将突变菌株的数据与原始菌株的数据进行比较。
