Sticky Business: Mineral-Microbe Geochemistry

September 23, 2009

Tracy Bank

Dept. of Geology, SUNY at Buffalo

The strength of bacterial adhesion to a mineral surface is a function of aqueous geochemistry and surface properties of both the bacterium and mineral. Additionally, studies have also shown that the metabolic state of bacteria influences the strength of adhesion to a surface. In this research we investigate the inverse problem, the influence of adhesion on bacterial metabolism. Mineral surface charge may significantly influence bacterial metabolism through regulation of ATP synthesis.
