[The chemotactic properties of Bradyrhizobium japonicum in the presence of natural fine-grained minerals].
The natural argillaceous minerals montmorillonite and palygorskite were found to enhance the motility of Bradyrhizobium japonicum cells and to slow down their chemotactic motion to glucose. The latter effect of the minerals is probably due to the adsorption of mineral particles on the cell surface and the blockade of the receptors that are responsible for the chemotactic behavior of the bacterium.
