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 various microorganisms. Glucose is a simple sugar and a primary energy source for bacterial cell metabolism. It is a common natural sugar involved in processes such as energy production, glycosylation, and formation of glycans that provide structure to cells. It is involved in a detrimental process in cells called glycation.
