Descripción general

D-(+)-Melibiose is a reducing disaccharide composed of a unit of galactose linked to a unit of glucose by a glycosidic bond α (1 → 6). It is commonly found in plants and the roots of certain legumes. D-(+)-Melibiose is not metabolized by humans but serves as a substrate for certain bacteria and fungi. It is used as a differential medium component in microbiological media to detect the fermentation of melibiose by microorganisms. It helps identify specific bacterial species based on their ability to ferment melibiose.

Aplicación

D-(+)-Melibiose has applications in the fields of microbiology, research and development, and in food and pharmaceutical industries. Melibiose fermentation test is used to differentiate bacteria like Enterobacteriaceae (like Salmonella, E.coli, shigella, Citrobacter, Klebsiella, Enterobacter) and yeasts. It is also used for the differentiation between the plant pathogenic bacteria Klebsiella pneumoniae and K. variicola.

Melibiose monohydrate has shown promise when employed as a pharmaceutical excipient, but its physical properties have not been adequately characterized. Therefore, two different melibiose monohydrate batches were analyzed as received or after storage under different relative humidity (RH) atmospheres. The
