ABSTRACT:
A method of concentrating microorganisms, particularly pathogenic microorganisms, from food and/or water potentially contaminated by dilute densities of the organisms is described. Potentially contaminated water or fluid food is directed along an elongated flow path which rests generally within a plane perpendicular to an axis of rotation, and is subjected to centrifugal forces by rotating the flow path about the rotational axis. The method may be executed by use of a conventional continuous flow channel-type blood plasmapheresis centrifuge.
