DD028-1VL is referred as Cellobiose Ce disc under HiMedia catalogue. Cellobiose discs are Carbohydrate Differentiation Discs, applicable in differentiation of bacteria on the basis of carbohydrate fermentation abilities. When a carbohydrate is fermented by a microorganism, the acid (or acid and gas) produced lowers the pH of the medium and the indicator in the basal medium thus changes colour.
