Details
Lactose broth medium is used for the detection and/or verification of the presence of coliform organisms in water, foods, and dairy products. The powder is homogeneous, free flowing and light beige. Visually the prepared medium is light yellow and clear. The expected cultural response is after 18-24 hours at 35.0°C. Lactose Broth is prepared according to the formulation specified by the APHA for use as a fermentation broth medium in the microbiological analysis of food, milk products and water. The broth is used to detect and/or verify the presence of lactose fermenting, Gram negative, aerobic microorganisms. In the examination of milk products Lactose Broth is used only for the completed test. The determination and confirmation of coliforms in water other than drinking water is performed by using Lactose Broth. Lactose Broth provides good growth characteristics for coliforms and fermentation is observed by gas bubbles present in an inverted fermentation tube. The concentration of media prepared for the test should be adjusted to accommodate for a volume of sample greater than 10mL. The sealed bottle containing the dehydrated medium should be stored at 2°C to 8.0°C. Once opened and recapped, the container should be placed in a low humidity environment at the same storage temperature. It should be protected from moisture and light. The dehydrated medium should be discarded if it is not free flowing or if the color has changed from the original yellowish beige color. Alpha Biosciences® #: L12-105-2KG.
