STRUCTURAL STUDIES OF THE TEICHOIC-ACIDS FROM BACILLUS-LICHENIFORMIS

Three teichoic acids have been isolated from Bacillus licheniformis. T heir structures were found to be 1,3 poly(glycerolphosphate), -->3)-al pha-D-Gal p-(1-->1)-L-glycerol-(3 --> phosphate, and --> 3)-[beta-D-Gl c p-(1-->2)]-alpha-D-Gal p-(1-->1)-L-glycerol-(3 --> phosphate. Withou t separating the individual teichoic acids, and despite their high mol ecular weight, these polysaccharides could be identified by modern NMR techniques alone.
