Research Abstract

Research areas in cellulose digestion have generally attracted many people as it could be converted to non-harmful bioethanol in a reasonable price. Termites digest plant biomass efficiently in both the midgut and the hindgut digestive systems, In the present study, the hindgut celluloytic systems were primarily analyzed. As a result, diverse genes relevant to lignocellulose decompositions and to carbohydrate-binding modules were obtained. Detailed analyses suggest that the termites are equipped with dual digestive systems, in which the midgut system hydrolyzes cellulose and the hindgut system is primarily involved in hemicellulose degradations.
