Composition of cellulase complex of Clostridium thermocellum

Abstract

It is thought that the anaerobic thermophilic cellulolytic bacterium C. thermocellum has the potential for direct industrial bioconversion of cellulose into ethanol. Therefore, much attention has been given to the study of the cellulolytic properties of the culture and to the characteristics of the cellulose complex, which is still not completely understood. Hence, the activity and location of various cellulolytic enzymes of C. thermocellum were determined. C. thermocellum has 6 known cellulolytic enzymes. Endoglucanase, cellobiohydrolase and exoglucosidase are extracellular enzymes (99-100 percent of the activity is located outside the cells) while cellulobiases, cellobiose phosphorylase and cellodextrine phosphorylase are inside the cells (80-90% of the activity). 25 references.
