D-Alanyl-substituted glycerol lipoteichoic acid in culture fluids of Streptococcus mutans strains GS-5 and BHT.
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.
