Study of the influence of plant phenolics on the surface properties and structure of glykopolymers of the bacterium Azospirillum brasiense SR55

It is shown that the cultivation of Azospirillum brasilense SR55 in the presence of rutin and quercetin leads to changes in the physicochemical properties of the surface of bacterial cells, and induces the synthesis of lipopolysaccharide, that differs from the original one in the structure of antigenic determinants, macromolecular organization, monosaccharide composition and the ratio of fatty acids.
