Discovery Of New Enzyme System Sheds Further Light On High Cellulolytic Performance Of C. thermocellum
C. thermocellum utilizes not only all the cellulase degradation mechanisms known today (cellulosomes and free enzymes), but also a new category of scaffolded enzymes not attached to the cell. This discovery explains C. thermocellum's superior performance on biomass. These scaffoldins were found to be essential for the well known digestion mechanism, i.e., the defibrillation of plant cell walls.
