Mesentericin Y105, a bacteriocin produced by a Leuconostoc mesenteroides strain, dissipates the plasma membrane potential of Listeria monocytogenes and inhibits the transport of leucine and glutamic acid. It also induces an efflux of preaccumulated amino acids from cells. In addition, the bacteriocin uncouples mitochondria by increasing state 4 respiration and decreasing state 3 respiration. Th...
Ginsenoside Rb1is the main component in ginsenosides. It is a protopanaxadiol-type ginsenoside that has a dammarane-type triterpenoid as an aglycone. In this study, ginsenoside Rb1 was transformed into gypenoside XVII, ginsenoside Rd, ginsenoside F2 and compound K by glycosidase from Leuconostoc mesenteroides DC102. The optimum time for the conversion was about 72 h at a constant pH of 6.0 to 8...
Also described as low viscous or low viscosity dextran, dextran 40 is prepared by acid hydrolysis and differential fractionation of a crude macromolecular polysaccharide produced from the fermentation of sucrose by the bacterium, Leuconostoc mesenteroides (strain B-512). The crude material is composed of linked glucose units. In the fraction represented by dextran 40, 80% of the molecules have ...
