µPREP™ Lactose Broth

Product Code: MPB003

Lactose Broth is frequently used as a pre-enrichment medium when testing foods and dairy products for Salmonella spp.

In dried or processed foods, Salmonella species may be sub-lethally injured and in low numbers. The presence of other bacteria as well as components of the food sample may hinder growth and recovery of Salmonella. Pre-enrichment in a non-selective medium, such as Lactose Broth, allows for repair of cell damage, dilutes toxic or inhibitory substances, and provides a nutritional advantage to Salmonella over other bacteria. Lactose Broth is widely used and is included in many procedures for testing foods, dairy products and other materials.

Gelatin peptone and beef extract provide the carbon and nitrogen sources for general growth requirements in Lactose Broth. Lactose is a carbohydrate source. Fermentation of lactose is demonstrated by the production of gas.
