Structural studies of the teichoic acids from Bacillus licheniformis

Three teichoic acids have been isolated from Bacillus licheniformis. Their structures were found to be 1,3 poly(glycerolphosphate), → 3)-α-d-Galp-(1 → 1)-l-glycerol-(3 → phosphate, and → 3)-[β-d-Glcp-(1 → 2)]-α-d-Galp-(1 → 1)-l-glycerol-(3 → phosphate. Without separating the individual teichoic acids, and despite their high molecular weight, these polysaccharides could be identified by modern NMR techniques alone.
