DEV LACTOSE PEPTONE BROTH 500 grams/bottle

Login For Price
Lactose Peptone Broth DEV is used for the enrichment and determining the titre of coliform bacteria in the bacteriological analysis of water according to the German Standard Methods for the examination of water and the German drinking water regulations (1990). Meat peptone and soy peptone provide nitrogen, vitamins, minerals and amino acids essential for growth. Lactose is the fermentable carbohydrate providing carbon and energy. Sodium chloride supplies essential electrolytes for transport and osmotic balance. Bromocresol purple is the pH indicator. All coliforms ferment lactose with acid and gas production. This group includes the genera Escherichia, Enterobacter, Citrobacter, and Klebsiella. When lactose is fermented it produces acid that changes the color of the medium from blue-purple (alkaline) to yellow (acid).
