Effect of surface potential on consumption of charged substrates.
Due to the surface charge inherent on all microorganism cell surfaces, the consumption of charged molecules by these microorganisms will be affected by the electrostatic interactions between the substrate and the cell surface. This article derives an equation that shows that these electrostatic interactions result in a change in the Monod half-velocity constant. The resulting rate of consumption is affected and can be either higher or lower than the rate of consumption of an uncharged substrate molecule.
