Seventy strains of 'viridans-group' streptococci were analysed gas chromatographically after preparation of trimethylsilyl ethers of their cellular sugars. The resulting profiles were evaluated as a possible aid to taxonomy. Glycerol, glucose, galactose, N-acetyl-glucosamine and N-acetylmuramic acid were found in all strains, in varying amounts. Rhamnose was the major neutral sugar in most strains, other than representatives of Streptococcus mitis, which invariably had ribose and usually anhydroribitol but no rhamnose. One strain of Strep. mitis possessed arabitol. Some strains of Strep. mitis and 'Strep. milleri' were alone in containing N-acetylgalactosamine. A combination of N-acetylgalactosamine and rhamnose in the absence of ribose was diagnostic for strains of 'Strep. milleri'.
对70株“草绿色链球菌群”链球菌的细胞糖制备三甲基硅醚后进行气相色谱分析。所得图谱被评估为可能有助于分类学研究。在所有菌株中均发现了甘油、葡萄糖、半乳糖、N-乙酰葡糖胺和N-乙酰胞壁酸，含量各不相同。鼠李糖是大多数菌株中的主要中性糖，但缓症链球菌的代表菌株除外，后者总是含有核糖，通常还有脱水核糖醇，但不含鼠李糖。有一株缓症链球菌含有阿拉伯糖醇。只有一些缓症链球菌和“米勒链球菌”菌株含有N-乙酰半乳糖胺。在没有核糖的情况下，N-乙酰半乳糖胺和鼠李糖的组合可作为“米勒链球菌”菌株的诊断依据。
