Abstract

The ethanol production from vegetal biomass degradation is an alternative to fossil fuels and a good way to reach the energy independence. This cellulose rich material is a renewable and unexhausted source whose degradation products (sugars) can be useful in ethanol production (second generation ethanol) generated by fermentative processes. However the recalcitrance of crystalline cellulose to enzyme treatment is an obstacle to popularize this product and the major biotechnological challenge in 21st century. Therefore the development of new catalysts or enzymes to enhance the ethanol production from vegetal sources becomes the main scientific challenge in this field. This process is based on identification, characterization and enzyme improvement not just individually but also to compose enzymatic cocktail. These enzymes are called cellulases and hydrolyse specifically²-1-4 glycosidic bonds in the middle of the cellulose chains (endoglucanases) or from cellulose chain ends (exoglucanases). The protein engineering methodology is a rational way to improve enzyme activity to reach a complete biomass degradation of insoluble raw material. In this scientific project we intend to study endoglucanases from GHF45 family and enzymes from GHF61 family, recently described as cellulose enhancer factors. Structural information will provide knowledge about enzymatic mechanism and basis for enzyme activity improvement. (AU)
