Increased β-glucosidase production and its application in agroindustrial residue hydrolysis: A research based on experimental designs.

β-Glucosidases are a limiting factor in the conversion of cellulose to glucose for the subsequent ethanol production. Here, β-glucosidase production by was optimized using Composite Central Designs and Response Surface Methodologies from a medium designed. The coefficient of determination ( ) was 0.9960, -value was very high, and the lack of fit was found to be non-significant. This indicates a statistic valid and predictive result. enzymatic extract was successfully tested as an enzymatic cocktail in a mixture design using sugarcane bagasse, soybean hull and barley bagasse. We proved that the optimization of the β-glucosidase production and the application in hydrolysis using unexpansive biomass and agricultural wastes can be accomplished by means of statistical methodologies. The strategy presented here can be useful for the improvement of enzyme production and the hydrolysis process, arising as an alternative for bioeconomy.
