Abstract:
In Algeria, the number of date palms exceeds the 17 million with more than thousand varieties and a production which reaches up to 700 thousand tons of dates. According to last information which we could collect, it arises that the rate of existing refuses is of 30% of the national production. These substrates, rich in sugars (65%) can be transformed by biotechnological processes to obtain ethanol with high degree. In our research task, we studied the possibility of using must of date refuses like substrate for the production of bio-ethanol and that by using the anaerobic bioconversion in the presence of the yeast Saccharomyces cerevisiae. During alcoholic fermentation, we followed the evolution of several parameters namely, the density and the rate of sugar. The degree of alcohol obtained after the first distillation was of 50° and after correction it exceeded the 90°. Lastly, it is possible to obtain each 72 hours of alcoholic fermentation 260 liters of ethanol starting from a ton of date refuses.
