[Adhesion of Azotobacter vinelandii IMV V-7076 and Bacillus subtilis IMV V-7023 on different surfaces].
The dependence of Azotobacter vinelandii IMV V-7076 and Bacillus subtilis IMV V-7023 adhesion on some parameters of dispersion media (pH, Ca 2+ ions presence) has been investigated. It has been determined that a decrease of bacteria negative charge determines an increase of the degree of their attachment to abiotic surface (glass) that corresponds to physicochemical regularities of the given process. The adhesion of bacteria on the biotic surface (cucumber roots) is not subordinated to generally accepted ideas, according to which the electrostatic repulsion between the interacting objects is one of factors that determines the adhesion effectiveness.
