Abstract	Arthropods living on plants are able to digest plant biomass with the help of microbial flora in their guts. This study considered three arthropods from different niches - termites, pill-bugs and yellow stem-borers - and screened their guts for cellulase producing microbes. Among 42 unique cellulase-producing strains, 50% belonged to Bacillaceae, 26% belonged to Enterobacteriaceae, 17% belonged to Microbacteriaceae, 5% belonged to Paenibacillaceae and 2% belonged to Promicromonosporaceae. The distribution of microbial families in the three arthropod guts reflected differences in their food consumption habits. Most of the carboxymethylcellulase positive strains also hydrolysed other amorphous substrates such as xylan, locust bean gum and β-D-glucan. Two strains, A11 and A21, demonstrated significant activity towards Avicel and p-nitrophenyl-β-D-cellobiose, indicating that they express cellobiohydrolase. These results provide insight into the co-existence of symbionts in the guts of arthropods and their possible exploitation for the production of fuels and chemicals derived from plant biomass.
