Abstract
Syrup resulting from date by-products constitutes a favorable medium for yeast development, owing to its sugar composition; it was hence tested for ethanol production. Three yeasts, Saccharomyces cerevisiae, Zygosaccharomyces rouxii and Candida pelliculosa, were selected for ethanol production on dates syrup. In batch fermentation, the ethanol concentration depended on the initial sugar concentration and the yeast strain. For an initial sugar concentration of 174.0 ± 0.2 kg mâ3, maximum ethanol concentration was 63.0 ± 0.1 kg mâ3 during S. cerevisiae growth, namely higher than the amounts achieved during Z. rouxii and C. pelliculosa growth, 33.0 ± 2.0 kg mâ3 and 41.0 ± 0.3 kg mâ3 respectively. Contrarily, only Z. rouxii was able to grow on 358.0 ± 1.0 kg mâ3 initial sugar amount, resulting in 55.0 ± 1.0 kg mâ3 ethanol produced.
