[Effect of cultivation conditions of Bacillus subtilis IMV B-7023 on surface properties of cells].
It has been established that the cells of Bacillus subtilis IMV B-7023 grown on the medium where peptone or calcium glycerophosphate served as the only source of carbon and energy have similar acid type of the surface and are characterized by a high negative charge even at low values of pH of the dispersion medium. This may be determined by the presence of phosphate groups, teichoic acids being their carriers in Gram-positive bacteria. Glucose addition to peptone or glycerophosphate leads to the change of the bacteria surface type, i.e., at low values of pH the cells have total positive charge, that allows to suppose availability of protein nature components in the surface layers of the cell wall. Bacteria grown in these conditions are also characterized by the higher degree of adhesion to inert carrier (glass).
