Nutrient Broth - 500g

Nutrient Broth is used for the cultivation of a wide variety of microorganisms. Nutrient Broth is not intended for use in the diagnosis of disease or other conditions in humans. In the early 1900�s, the American Public Health Association (APHA) suggested the formula of Nutrient Agar as a standard culture medium used in water testing. Nutrient Broth is the same formulation as Nutrient Agar, only Agar has been omitted. Nutrient Broth is used as a pre-enrichment medium when testing certain foods and dairy products for Salmonella spp. In dried or processed foods, salmonellae may be sub-lethally injured and in low numbers. The presence of other bacteria and food sample components may hinder growth and recovery of Salmonella spp. Pre-enrichment in a nonselective medium such as Nutrient Broth allows for cell damage repair, dilutes toxic or inhibitory substances, and provides a nutritional advantage to Salmonella over other bacteria. Nutrient Broth is included in many standard methods procedures for testing food, dairy products, and other materials.
