Abstract

The use of mango peel (agricultural waste with no appreciable value to industries or competitive use as food) as alternative and cost-effective biomass for the production of bioethanol was examined. Thus, the aim of this study was to select performed yeasts strains able to ferment sugars containing in peel mango. The methods used, included: enzymatic hydrolysis with Bacillus and simultaneous saccharification and fermentation with W6 and B1, yeasts isolated from wine and among bakers yeasts, respectively. The kinetics parameters results showed that the optimum alcohol releasing like 35% (g E/g S) and 30% (g E/g S) respectively from W6 and B1 be spread out at 40°C. The maximum volume of ethanol produced from peel mango by W6 and B1 were, respectively 13 and 10.1 g L ¯1 at the 120th.
