Abstract
The content and D-alanyl ester complement of lipoteichoic acid from stationary-phase culture filtrates of Streptococcus mutans (strains BHT and GS-5; serotypes b and c) were determined chemically and serologically. A third less lipoteichoic acid was obtained from strain GS-5 than from strain BHT. This lipoteichoic acid had an increased mobility on immunoelectrophoresis after exposure overnight at pH 8 and a 10-fold greater content of alanine per mole of glycerol.
摘要
对变形链球菌（菌株BHT和GS-5；血清型b和c）稳定期培养滤液中的脂磷壁酸的含量和D-丙氨酰酯补体进行了化学和血清学测定。从菌株GS-5获得的脂磷壁酸比从菌株BHT获得的少三分之一。这种脂磷壁酸在pH 8下过夜暴露后，在免疫电泳中的迁移率增加，每摩尔甘油的丙氨酸含量高出10倍。
