Description

Description

MacConkey broth is a selective culture medium containing lactose. When lactose breaks down, it produces acid and gas, which indicates the presence of E. coli. The resulting gas is collected in Durham tubes. The color of the bromocresol pH indicator changing from purple to yellow indicates acid formation. Ox bile promotes the growth of several types of intestinal bacteria and inhibits the growth of other microorganisms that do not inhabit the intestines.
