China Blue Lactose Agar 500G

China Blue Lactose Agar is recommended for differentiation and enumeration of bacteria in milk. The medium does not contain any inhibitory substances therefore all the organisms present in milk sample grow luxuriantly on this medium. Lactose is the fermentable sugar. China blue is the pH indicator that changes from colourless to blue due to degradation of lactose to acid, thus differentiating lactose-fermenters from non-fermenters.
