The objective of this study is the use of date syrup varieties Hmira like substrate for the growth of Saccharomyces cerevisiae. The study of the optimization of method extraction show that the mode of hot extraction increases the concentrations of sugars, dry matter, tannins and pectin relative to the cold extraction which promotes the extraction of vitamin C and proteins. The different physicochemical and biochemical analyzes show the richness of date syrup in nutritional elements that makes them favorable to the alcohol fermentation. Kinetic study of the growth of Saccharomyces cerevisiae shows that perfect adaptation of strain to the medium (date syrup) and the concentration of 60% of date syrup is favouring to the growth of this strain.
