Особенности состава и структуры липополиса харидов Azospirillum lipoferum Sp59b и Azospirillum brasilense SR55, выращенных в присутствии флавоноидов

Abstract

It is shown that the addition of flavonoids to the growth medium of bacteria Azospirillum lipoferum Sp59b and Azospirillum brasilense SR55 induces the synthesis of lipopolysaccharide, which differs from the original in macromolecular organization, structure, monosaccharide composition, ratio and a set of fatty acids in the lipid A. The data obtained show an important role of flavonoids in the associative relations of azospirilla and plant roots, implemented with the participation of bacterial lipopolysaccharide.
