Enzymatic production and complete nuclear magnetic resonance assignment of the sugar lactulose.
The enzymatic transgalactosylation from lactose to fructose leading to the prebiotic disaccharide lactulose was investigated using the beta-galactosidase from Aspergillus oryzae and theExpand

Biodiversity of refrigerated raw milk microbiota and their enzymatic spoilage potential.
The refrigerated storage of raw milk selects for psychrotolerant microorganisms, many of which produce peptidases and lipases. Some of these enzymes are heat resistant and are not sufficientlyExpand

Enzymatic production of lactulose and epilactose in milk.
The enzymatic production of lactulose was described recently through conversion of lactose by a thermophilic cellobiose 2-epimerase from Caldicellulosiruptor saccharolyticus (CsCE). In the currentExpand

Epilactose production by 2 cellobiose 2-epimerases in natural milk.
It was reported recently that cellobiose 2-epimerases (CE) from various aerobic microorganisms convert lactose to epilactose in defined buffer systems. In this study, we showed that CE from 2Expand

Pseudomonas lactis sp. nov. and Pseudomonas paralactis sp. nov., isolated from bovine raw milk.
Five strains, designated WS 4672T, WS 4998, WS 4992T, WS 4997 and WS 5000, isolated from bovine raw milk formed two individual groups in a phylogenetic analysis. The most similar species on the basisExpand

Recombinant expression, purification and characterisation of the native glutamate racemase from Lactobacillus plantarum NC8.
Glutamic acid racemases (MurI, E.C. catalyse the racemisation of L- and D-glutamic acid. MurIs are essential enzymes for bacterial cell wall synthesis, which requires d-glutamic acid as anExpand
