Termites are efficient lignocellulose degraders in the natural ecosystem. During the long-time evolution, termites have developed different strategies to decompose lignocellulose efficiently with the help of their gut microbiome. Wood-feeding termites have duel-cellulolytic systems that originated from termites and their microbiota. In lower termites, wood particles are digested primarily by endogenous cellulase secreted from the host foregut and midgut and then decomposed almost completely by numerous flag...
