Nutrient Broth No. 2 (Dehydrated), 500g

Cultivate fastidious pathogens and other microorganisms with nutritious Thermo Scientific™ Oxoid™ Nutrient Broth No.2 (Dehydrated). This medium is comparable to a meat infusion and is richer in nutrients than Nutrient Broth (CM0001). It gives good growth from small inocula and is recommended for sterility testing for aerobic organisms. It complies with the recommendations in the British Pharmacopoea for the composition of a sterility testing medium for aerobes. This non-selective medium contains beef extracts combined with peptone, Lab Lemco, and sodium chloride to provide the necessary nitrogen compounds, carbon, vitamins and some trace ingredients necessary for the growth of bacteria. The medium is ideally suited for sub-culture, particularly as a secondary growth medium for staphylococci which are to be tested for coagulase production. Nutrient Broth No.2 made up at double strength corresponds to the medium recommended by the British Standards Institution for use in the determination of the Rideal-Walker Coefficient of Disinfectants. Nutrient Broth No.2 is the basal medium for Preston Campylobacter Enrichment Broth.
