Poly(glucosylglycerol phosphate) teichoic acid in the walls of Bacillus stearothermophilus B65.

Abstract

1. Walls of Bacillus stearothermophilus B65 contain a glycerol teichoic acid in which repeating structures consisting of 1-O-alpha-D-glucopyranosylglycerol phosphate are held together by phosphodiester linkage between the glycerol and glucose moieties of adjacent units. 2. The walls are not agglutinated on incubation with concanavalin A, nor does the isolated teichoic acid form a precipitate with this lectin. 3. No evidence was obtained of the presence of the glucosylated (1 leads to 2)-poly(glycerol phosphate) teichoic acid which has previously been reported to occur in walls of this bacterium.
