Abstract
An experiment was initiated to investigate the production of ethyl alcohol using Zahdi date extract and pure sugar (sucrose) solutions in different concentrations as media and Saccharomyces cerevisiae as a starter. Through this investigation the following facts have been found: 0.5% ammonium phosphate as a source of nutrient was satisfactory; date extract of 25% and inoculum of 12% gave the highest yield of ethyl alcohol; however 15% of pure sucrose solution gave the maximum yield with a slight difference when compared with 20%; increasing the inoculum shortened the time of fermentation with no effect on inhibitory phenomenon; the rate of alcohol production was associated with the rate of yeast proliferation.
