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.
研究了一些因素对棕色固氮菌IMV V-7076和枯草芽孢杆菌IMV V-7023趋化性及其对黄瓜根附着力的影响。葡萄糖趋化性和对根的附着力在每个菌株特有的pH范围内达到峰值。棕色固氮菌IMV V-7076的这些范围是7.0 - 8.0，枯草芽孢杆菌IMV V-7023的是6.0 - 7.0。在混合悬浮液中，每个物种的附着力值显著降低。每个菌株与粘土矿物蒙脱石的相互作用提高了它们对黄瓜根的附着力。粘土矿物坡缕石提高了棕色固氮菌的附着力，但降低了枯草芽孢杆菌的附着力。
