Abstract

In an X-ray laboratory study the interaction of bacteria with a sterile montmorillonite suspension was studied. It was found that the inoculation of the sterile montmorillonite suspension with a culture of soil bacteria resulted in adhesion and aggregation of montmorillonite platelets on the surface of bacterium cells. The platelets appear to be stuck in bacterial slime in a typical edge-to-face association, parallel to each other. The adhesion is due to the extracellular polysaccharides produced by the soil bacteria.
