DEV LACTOSE PEPTONE BROTH

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.
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).
