✦ Synopsis

The structures of the capsular polysaccharides elaborated by Klebsiella types 8 (K8) and 82 (K82) have been reinvestigated. N.m.r. spectroscopy of the original and chemically modified polysaccharides was the principal method used. It is concluded that the polysaccharides are composed of repeating units having the following structures. (Formula: see text). The presence of L-glutamic acid, linked as an amide to the carboxyl group of a uronic acid, has not been observed hitherto in bacterial polysaccharides.
