Application:	D-(+)-Cellobiose has been used: • as a component in test sugar solution for cellobiose-mannitol permeability test • in the preparation of lyophilization solutions to study its ability to protect lyophilized β-galactosidase from enzymatic activity loss and secondary structure changes during storage • as a fermentation/growth substrate to grow Clostridium thermocellum to study its impacts on the qualitative and quantitative changes in cellulosome composition
General description:	Cellobiose, a disaccharide, is made up of two d-glucose molecules linked by a β-1,4-glycosidic bond. This reducing sugar can mutarotate and is produced by hydrolysis of cellulose.
