الملخص EN

Ethanol production from lignocellulosic substrates, such as sugar cane bagasse and corncobs was evaluated using Saccharomyces cerevisiae in this study.

The hydrolysates were prepared with 0.5% H2S04 and solid / liquid ratio of 3: 10 (w / v) at 121 °C for 2h.

Hydrolysates were supplemented with ammonium sulfate, dipotassium hydrogen phosphate; magnesium sulfate and yeast extract to prepare the growth medium.

Fermentation experiments were carried out at 30 °C.

The influence of different aeration rates, pH and initial sugar concentration on the growth kinetics and ethanol production were investigated.

The highest biomass growth and ethanol production rates were obtained at pH 4.5 and aeration rate of one w-1 m~H The results obtained with initial sugar concentration were approximately similar with those of 6.9 or 7.5% for sugar cane bagasse and corn cobs hydrolysates, respectively.

The highest overall yield coefficient of ethanol on sugar consumed (Yp/s) or on biomass, formed (Yp/x) were 0.46 and 2.88gg-1 for yeast strain grown on sugar cane bagasse hydolysate medium.
