  • Patent number: 5578460
    Abstract: The present invention sorts microorganism populations from a mixture which contains more than one microorganism population. Microorganisms of different types vary in size, shape, and surface charge characteristics. These characteristics we believe contribute to the rate of migration for microorganisms under the influence of an electric field. Microorganisms of the same population (genus and species) will migrate similarly. By applying an electric field in a direction opposite the direction of fluid flow, separation is enhanced.
