Abstract
Neither muramic acid and glucosamine nor D-glutamic acid or other amino acids typical of peptidoglycan were found in cell walls of two strains of Methanosarcina barkeri. The main components are galactosamine, neutral sugars and uronic acids. Therefore, the structural component of the cell wall most likely consists of an acid heteropolysaccharide, resembling that of Halococcus morrhuae. It is, however, not sulfated.
摘要
在巴氏甲烷八叠球菌的两株菌株的细胞壁中，既未发现胞壁酸和氨基葡萄糖，也未发现D - 谷氨酸或肽聚糖特有的其他氨基酸。主要成分是半乳糖胺、中性糖和糖醛酸。因此，细胞壁的结构成分很可能由一种酸性杂多糖组成，类似于盐沼盐球菌的细胞壁。然而，它没有硫酸化。
