Abstract: | It was found that atypical R-S dissociation in the type strain A. brasilense Sp7 is not accompanied by drastic changes in the carbohydrate moieties of bacterial lipopolysaccharides but is rather due to different contributions of two O-specific polysaccharides (found in both R and S dissociants) to the age-dependent architectonics of the cell surface. |
