FLUID LACTOSE MEDIUM (LACTOSE BROTH) (as per USP)

Fluid Lactose Medium is recommended by APHA and United States Pharmacopoeia in the performance and confirmation of the presumptive test for coliform bacteria in water, food and milk. This medium can be used as an alternate to Lauryl Sulphate Broth in the presumptive test of the MPN of standard coliforms. This medium is also used for pre-enrichment of Salmonella for its detection in pharmaceutical raw materials.
Members of the coliform group are defined as aerobic and facultative anaerobic gram-negative and non-sporing bacilli which ferment lactose with gas formation within 48 hours at 35?C. In testing dairy products, Fluid Lactose Medium is used only in the completed test. Large water samples may require double strength Fluid Lactose Medium to minimize the final volume.
