General description

Lactose Discs are used to differentiate bacteria based on the lactose fermentation ability. Microorganisms can only ferment certain carbohydrates, depending on the enzymes they possess to break down carbohydrates. Fermentation can be detected by gas production (CO2) in liquid mediaand/or color change of pH caused by acid production. The lactose discs are aseptically added to any sugar-free basal media to test the ability of the organism to hydrolyze lactose as the sole source of carbon and energy during fermentation. Lactose is typically fermented under acid production by all coliform bacteria.

Application

Lactose Discs are recommended to detect lactose fermenting bacteria in food and environmental samples. They find their application in various sectors such as the food and dairy industry, water industry, pharmaceutical laboratory testing, cosmetic industry, environmental and sanitary testing, clinical diagnostic, etc.
