Description

Description générale

D-(+)-Glucose monohydrate, commonly known as glucose or dextrose, has several microbiological applications. It is used as a carbon source in microbial culture media to promote the growth and propagation of variety of microorganisms. Glucose is a simple sugar and a primary energy source for bacterial cell metabolism. Glucose monohydrate can also be used as a supplement in media to enhance the growth and productivity of microorganisms used in fermentation processes, for example, in the production of antibiotics, organic acids, and enzymes. It plays an important role in diauxic growth, which refers to the phenomenon in which bacterial cells preferentially utilize glucose as a carbon source before switching to other energy sources. In addition, glucose is a common component in numerous selective and differential media formulations used in the identification and characterization of microorganisms.

Application

D-(+)-Glucose monohydrate is commonly used as an ingredient in many microbial culture media for the growth and identification of bacteria, yeasts, and molds from various pharmaceutical, environmental, and food and beverage samples.
