Description

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.

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
