in ethanol production, we evaluated 25 treatments in a completely randomized factorial arrangement 5 x 5, involving 5 types of hydrolysis (natural, acidic, alkaline, enzymatic with cellulases and pectinases) and 5 of the yeast inocula Saccharomyces cerivisiae (natural, two commercial yeast and two yeast commercial dry). The pulp of coffee, no water from the pulping of the fruit, was used less than 1 hour generated, acid hydrolysis was performed with concentrated sulfuric acid, alkaline hydrolysis with sodium hydroxide sodium to 32%, enzymatic hydrolysis was performed by adding commercial cellulases and pectinases. A pulp samples were evaluated pH, % humidity and °Brix and the final samples rectified and dehydrated alcohol were evalueted alcohol content and the main congeners. Analysis of variance showed the interaction effect of hydrolysis-seed yields of alcohol and the pH, °Brix and Specific Gravity. Constrate test showed 5% higher performance treatments in the production of alcohol and among which there were no statistical differences were those that involved the enzymatic hydrolysis with cellulases (22,12 mL.kg-1 of fresh pulp), followed by enzymatic hydrolysis with cellulases-pectinases (20,96 mL.kg -1 of fresh pulp) and treatments without hydrolysis (18,30 mL.kg-1 of fresh pulp). The highest mean levels of ethanol were achieved for treatments with cellulase enzymatic hydrolysis (97,78%), followed by treatment without hydrolysis (96,92%) of treatment with enzymatic hydrolysis using cellulases and pectinases (95,76%), treatment with alkaline hydrolysis (95,59%) and treatment with acid hydrolysis (93,97%).
