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

Economic feasibility and sustainability of lignocellulosic ethanol production requires the development of robust microorganisms that can efficiently degrade and convert plant biomass to ethanol. The anaerobic thermophilic bacterium Clostridium thermocellum is a candidate microorganism as it is capable of hydrolyzing

A 160 kDa enzyme with beta-glucosidase activity was purified from the midgut gland of the land crab Gecarcoidea natalis. The enzyme was capable of releasing glucose progressively from cellobiose, cellotriose or cellotetraose. Although beta-glucosidases (EC 3.2.1.21) have some activity towards
