KINETIC STUDY OF FERMENTATION OF FERMENTABLE SUGARS PRESENT IN DATES VARIETY GHARS OF EL OUED REGION

Dates variety Ghars from the region of El Oued in the south east of Algiers these dates rich in fermentable sugars are used for the production of bioethanol by fermentation. In this study we prepared bioethanol by fermentation of date must at the laboratoryl, to understand the kinetics of this transformation we followed the evolution of the must density, the sugar content, the pH and the absorption light at 490nm during fermentation
