The cell wall chemical composition of Streptomyces chrysomallus producing the antibiotic aurantin was studied. The cell wall represents 11--13% of the dry cell weight and contains three major polymers, namely, peptidoglycan, ribitol teichoic acid and a polysaccharide. Each muramic acid of peptidoglycan has a peptide subunit which consists of two alanine residues, glutamic acid and diaminopimelic acid residues. Peptide chains are connected with bridges consisting of one glycine residue. The poly(ribitol phosphate) chain contains glucosyl substituents and O-acetyl groups. The main monosaccharides of the polysaccharide are glucose and galactose; mannose, fucose and galactosamine are found in minor amounts. The composition of the cell wall changes during cell development and aging: the content of teichoic acid decreases while that of the polysaccharide increases. Possible factors causing these changes are discussed.
对产生抗生素金橙素的金色链霉菌的细胞壁化学成分进行了研究。细胞壁占干细胞重量的11% - 13%，包含三种主要聚合物，即肽聚糖、核糖醇磷壁酸和一种多糖。肽聚糖的每个胞壁酸都有一个肽亚基，该肽亚基由两个丙氨酸残基、谷氨酸和二氨基庚二酸残基组成。肽链通过由一个甘氨酸残基组成的桥连接。聚（核糖醇磷酸）链含有葡萄糖基取代基和O - 乙酰基。多糖的主要单糖是葡萄糖和半乳糖；少量存在甘露糖、岩藻糖和半乳糖胺。细胞壁的组成在细胞发育和老化过程中会发生变化：磷壁酸的含量减少，而多糖的含量增加。讨论了导致这些变化的可能因素。
