LACTOSE BROTH (FLUID LACTOSE MEDIUM) (VEG.)

Description

Examination of water, foods, ingredients and raw materials, for the presence of marker groups such as coliforms is one of the most common tests in a microbiology laboratory, partly because of the relative ease and speed with which these tests can be accomplished. It is a valuable bacterial indicator for determining the extent of fecal contamination of recreational surface waters or drinking water. Lactose Broth (Veg) is prepared by using vegetable peptone in place of animal based peptone, making the medium free of BSE/TSE risks. Lactose Broth (Veg) is the modification of Lactose Broth which is recommended by APHA in the performance and confirmation of the presumptive test for coliform bacteria in water, food and milk. This medium was initially listed as an alternative to Lauryl Sulfate Broth in the presumptive Standard Total Coliform Multiple-Tube (MPN) Test for water analysis.
