Abstract
Methods for rapidly concentrating a food sample for efficient detection of bacteria are disclosed. A microfiltration approach followed by centrifugation was used to concentrate the cells with an enzyme (e.g., a protease) added at the beginning of the process to facilitate more efficient micro-filtering. The enzyme was found to have no significant effect on cell viability.
