Resumen:
The objective of this work was to find the optimal conditions of enzymatic hydrolysis of the rice husk pretreated with sodium hydroxide in an autoclave at 121° C.Screening design showed that all the selected variables (FPU / g substrate, pH, agitation, time, temperature and concentration of surfactant) were statistically significant. Then an optimization design was applied for the variables: pH, FPU and time, discarding the ones with the lowest level of significance. Finally, the best conditions found in the previous designs were (pH 5.0, 13 h, and 30 FPU / g of substrate) subsequently these conditions were applied in experiences to evaluate the influence of the increase in hydrolysable cellulose, using 6%; 8% and 10% of cellulose available giving saccharification yields of 74%, 42% and 16%.
