title: [Chemotactic and adhesive properties of Azotobacter vinelandii and Bacillus subtilis].
abstract: The effects of some factors on the chemotaxis of Azotobacter vinelandii IMV V-7076 and Bacillus subtilis IMV V-7023 and on their adhesion to cucumber roots have been studied. Glucose chemotaxis and adhesion to roots reach peak values in pH ranges characteristic of each strain. These ranges are 7.0-8.0 for A. vinelandii IMV V-7076 and 6.0-7.0 for B. subtilis IMV V-7023. The adhesion values of each species decrease significantly in their mixed suspension. The interaction of each of the strains with the clay mineral montmorillonite improves their adhesion to cucumber roots. The clay mineral palygorskite improves the adhesion of A. vinelandii but reduces that of B. subtilis.
