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. Portrait All That Matters Rarest. 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. Rising concern over the cost and sustained availability of fossil fuels has increased demand for the development of alternative and preferably renewable fuel resources, with lignocellulosic biomass as one promising resource. Lignocellulose represents ~90% of the dry weight of all plant materials, is primarily composed of the sugar polymers cellulose (35–50%) and hemicellulose (20–35%) together with lignin (5–30%) that provides structural support for the plant. Cellulose and hemicellulose represent abundant and inexpensive sources of fermentable sugar for the production of various chemicals and biofuels, but finding efficient catalysts for their saccharification to monomeric sugar and producing those catalysts in a cost-effective manner are major hurdles.

Marchinhas De Carnaval Midi Download For Mac. The enzymatic hydrolysis of cellulose polymers is achieved by the synergistic activity of three different groups of cellulase enzymes: endoglucanase, exoglucanase or cellobiohydrolase, and β-glucosidase.
