Descrição geral

Cellobiose is a disaccharide that is a reducing sugar. It is added to culture media as a nutrient supplement, specifically as a carbohydrate source, and can be used to differentiate bacteria based on their ability to ferment cellobiose. For example, Vibrio spp. can ferment cellobiose which results in acid production and can be indicated by the pH indicator bromothymol blue, which turns yellow at acidic pH. The addition of cellobiose in the media also stimulates the initial growth of Salmonella.

Aplicação

Cellobiose has applications as a carbohydrate source in culture media and biochemical characterization of microorganisms, based on their carbohydrate fermentation abilities
