一般描述

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.

应用

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.

The ice recrystallization inhibition activity of various mono- and disaccharides has been correlated with their ability to cryopreserve human cell lines at various concentrations. Cell viabilities after cryopreservation were compared with control experiments where cells were cryopreserved with dimethylsulfoxide (DMSO).

The melibiose permease of Salmonella enterica serovar Typhimurium (MelB(St)) catalyzes symport of melibiose with Na(+), Li(+), or H(+). Bioinformatics and mutational analyses indicate that a conserved Gly117 (helix IV) is a component of the Na(+)-binding site. In this study, Gly117

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
