Production of Bioethanol from Corn Straw by Co-Immobilization of Saccharomyces Cerevisiae and Aspergillus Niger in Na-Alginate

EasyChair Preprint no. 6198

Abstract

Bioethanol from corn straw was produced using Saccharomyces cerevisiae and Aspergillus niger co-immobilized on Na-Alginate. Corn straw was mechanically and chemically pre-treated using NaOH before hydrolysis and fermentation. Cell of S. cerevisiae and A. niger were immobilized individually and simultaneously on Sodium Alginate gel beads. These immobilized cells were utilized to proceed the corn straw into bioethanol. The effect of using co-immobilized cells of S. cerevisiae and A. niger will be compared with the usual technique where the immobilized cells were applied separately and sequentially. The composition of S. cerevisiae and A. niger were also studied. Hydrolysis and fermentation were carried out at 30°C, pH 4 and 150 rpm in shaker incubator. Yield and quality of bioethanol were studied. Reusability of immobilized cells were also studied. The co-immobilisation of S. cerevisiae and A. niger will made proses simpler, inexpensive and less energy due to its less sequential process and the reusability of cell.
