title: Occurrence of pyruvic acid in capsular polysaccharides from various Klebsiella species.
abstract: Capsular polysaccharide materials from several different klebsiella serotypes were demonstrated to contain an alpha-keto acid characterized as pyruvic acid. Linkage to the capsular polysaccharides was shown to be acid labile and alkali stable, suggesting ketosidic rather than ester linkages.
