[The mitogenic activity of the glycopolymers from Clavibacter (Corynebacterium) michiganense and Pseudomonas solanacearum].

A comparative study of the mitogenic activity of glycopolymers has shown that the activity of polysaccharides isolated from Clavibacter michiganense is higher than that of lipopolysaccharide of Escherichia coli, Pseudomonas solanacearum and mefenaminic acid (the synthetic mitogen). Lipid A and the core oligosaccharide fraction are established to be responsible for the mitogenic activity of the P. solanacearum lipopolysaccharide. O-specific chains and fractions of KDO-phosphates do not manifest the mitogenic activity.
