The essence of bioconversion of sugar containing materials by the use of screened microbial source is the significant need of today. Saccharomyces cerevisiae is one of the common and the cheapest source of bioconversion of substrate to the higher yield of bioethanol under the controlled optimization parameters. In the present study Saccharomyces cerevisiae strains ASN-3 and HA-4 were activated and finally used for ethanol fermentation from Dates. The results revealed that both strains are actively involved in fermentation process but it is concluded that strain HA-4 resulted higher cellular mass when inoculated in Malt Yeast extract Peptone Glucose medium supplemented with fructose and yeast nitrogen base and higher yield of ethanol was also observed when the activated strain were inoculated in dates syrup as substrate at 120 rpm, having pH 4.5 at 30 degree C at 600 nm after 72 h post incubation.
