UNIVERSAL PRE-ENRICHMENT BROTH

Environmental stress induces sublethal injury or metabolic damage to microbial cells. Recovery of such damaged microbial cells is achieved by growth in a non-selective media prior to isolation on selective media. Injury may result from many food processing and handling methods, including thermal treatment, refrigeration, freezing, drying and irradiation or from exposure to preservatives, acidity or low water activity. Universal Pre-enrichment Broth, formulated by Bailey and Cox, is different from the other enrichment broths that either contains antibiotics or are not sufficiently buffered to support injured bacteria.
