一般描述

Buffered peptone water in bags is a pre-enrichment medium designed to help the recovery of sub-lethally damaged microorganisms before transferring to a selective medium. This pre-enrichment medium is free from inhibitors and is well buffered and provides conditions for resuscitation of the cells that have been injured by processes of food preservation. The media contains Peptone including an enzymatic digest of casein as a source of carbon, nitrogen, vitamins, and minerals. Sodium chloride maintains the osmotic balance and phosphates buffer the medium. The broth is rich in nutrients and produces high resuscitation rates for sub-lethally injured bacteria and supports intense growth.

应用

Buffered Peptone Water is used as :
  • a non-selective pre-enrichment medium for the detection of Salmonella in food products and environmental specimens. It complies with the standard EN ISO 6579 (1) and amendment A1 (annex D) (8),
  • a diluent for the enumeration of the micro-organisms. It complies with the standards EN ISO 6887 (2, 3, 4, 5) and 8261 (6),
  • a diluent for the enumeration of Listeria monocytogenes. It complies with the standard EN ISO 11290-2 (7).
