| Outline of Final Research Achievements |
Cellulosome-producing thermophilic anaerobic Clostridia play a pivotal role in the degradation of cellulosic biomass in a thermophilic methanogenic bioreactor. The cellulosome is a supramolecular multienzyme complex composed of a wide variety of polysaccharide-degrading enzymes and structural proteins, and displayed on the cell surface of anaerobic cellulolytic bacteria. Cellulosomal enzymes bound to the structural proteins generate synergy for the degradation of crystalline substrates, such as crystalline cellulose and plant biomass. In this study, we constructed a recombinant thermophilic anaerobic bacterium, which produces enzymes that are not naturally present in the cellulosome complex, beneficial to the fermentation of renewable bio-based fuels and chemicals.
