| Research Abstract |
Cellulase/hemicellulases supramolecular complex(cellulosome) from thermophilic anaerobe Clostridium thermocellum shows a high saccharification activity for crystalline cellulose. In this study, we analyzed the saccharification activity of the C. thermocellum supramolecular cellulosome, which is in vitro reconstituted from cell-free synthesized cellulosomal components. As a result, it was revealed that the saccharification activity for crystalline cellulose increased along with an increase in the number of cellulosome-binding domains(cohesins) in the scaffolding protein. Furthermore, we successfully isolated four cohesin genes from a compost metagenome.
