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.
