ETHANOL PRODUCTION FROM CASSAVA STARCH USING THE PROCESS STRATEGY SIMULTANEOUS SACCHARIFICATION-FERMENTATION

The world trend on fuel management, in special biofuels like ethanol, have gone to explorer new methodologies of process to optimize its production by this reason in this research is about simultaneous sacarification fermentation process and evaluate initial concentration of reducing sugar, and enzy...
