Cellobiose Disks

Cellobiose Discs are used to differentiate bacteria based on the cellobiose 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 media and/or color change of pH caused by acid production. The cellobiose discs are aseptically added to any sugar-free basal media to test the ability of the organism to hydrolyze cellobiose, a reducing disaccharide, as the sole source of carbon and energy during fermentation. Cellobiose is typically fermented under acid production by many Enterobacter bacteria.

Cellobiose Discs are recommended to detect cellobiose 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.
