title: Structure of the glycocalyx polysaccharide of Pseudomonas fragi ATCC 4973.
abstract: The structure of the exocellular glycocalyx polysaccharide of Pseudomonas fragi ATCC 4973, a bacterium implicated in the spoilage of meat, has been determined using hydrolysis, methylation analysis and 1D- and 2D-n.m.r. spectroscopy. The polysaccharide, which aids in the adhesion of the cells to each other and to the meat tissue, has the regular repeating unit ----4)-3-O-[(R)-1-carboxyethyl]-alpha-D-Glcp-(1----3)-beta-D-ManpNAc+ ++- (1----4)-beta-D-Glcp-(1----. Random partial O-acetylation occurred in some preparations of the polysaccharide.
