Cellulose is the most abundant natural resource on Earth. As one of the most efficient cellulose decomposers in the nature, termites are becoming more and more attractive for scientists for their capabilities to degrade cellulose and potential application in the new biomass energy industry. It has been reported that termites degrade cellulose by the use of both cellulases secreted by themselves and the cellulases originated from their gut symbiotic microbes. The cellulases involved in the cellulose degradat...
