Influence of Pseudomonas syringae pv. atrofaciens lipopolysaccharide on spontaneous and induced by bichromate potassium mutagenesis in Salmonella typhimurium

Summary

It has been established that lipopolysaccharides (LPS) are not mutagens. LPS in concentration of 1000 g per plate reduced spontaneous mutations of S. typhimurium TA100 by 16 % and S. typhimurium TA98 by 31 %. P. syringae pv. atrofaciens 8281 LPS is the antimutagen against bichromate potassium too. LPS can reduce the frequency of induced by bichromate potassium mutations S. typhimurium TA98 by 57-78 %, S. typhimurium TA100 by 14- 49 %. P. syringae pv. atrofaciens 8281 LPS has neither stimulation nor toxic effect on S. typhimurium.
