Characterization of novel galactosylated chitin-oligosaccharides and chitosan-oligosaccharides [PDF]
International Dairy Journal, 2014 This study determined whether chitin-oligosaccharides and chitosan-oligosaccharides (COS) are suitable acceptor carbohydrates for the LacLM-type β-galactosidase of Lactobacillus plantarum. Enzymatic reactions were carried out with lactose as galactosyl-donor and chitinbiose (N,N′-diacetyl chitobiose), chitintriose (N,N′N″-triacetyl chitotriose) or a ...
