Description

General description

The sorbitol fermentation test is based on the fermentation ability of sorbitol which results in the production of acid as end products, the pH of the liquid basal medium will drop, and an indicator changes the color to red. Some organisms produce additional CO₂ gas which can be made visible with a Durham’s tube. Sorbitol can for example be used to differentiate enterohemorrhagic Escherichia coli (EHEC) but also for other Enterobacteriaceae.

Application

Sorbitol Discs are recommended to detect sorbitol 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.
