Erwinia chrysanthemi O antigen is required for betaine osmoprotection in high-salt media.

ABSTRACT: Cellular components necessary for osmoprotection are poorly known. In this study we show that O antigen is specifically required for the effectiveness of betaines as osmoprotectants for Erwinia chrysanthemi in saline media. The phenotype is correlated with the inability of rfb mutant strains to maintain a high accumulation level of betaines in hypersaline media.
