Abstract

Plant cell wall polysaccharides are sustainable products with high biotechnological potential, and the conversion of these polymers into fermentable sugars is one of the main challenges of this production chain. Identification and characterization of genes and enzymes which are active in carbohydrate as well the proteins with complementary actions in this approach, are crucial for increasing efficiency in the hydrolysis of lignocellulosic compounds. Regarding to that, termites are ecologically considered as a natural bioreactor in lignocellulosic materials conversion into sugars, which are the basis of their feeding, and therefore, play an important role being responsible for around 90% of plant material degradation in tropical forests. The reason for this would be its enzymatic pool (endogenous and symbiotic). In literature as well results obtained by our group, evidences that others mechanisms may act complementing the cellulases actions in termites digestoma. In this way, the main goal of this project is the investigation of redox enzymes which can act in synergism with glycolytic hydrolases in the degradation of lignocellulosic biomass. (AU)
