N2 - 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. The cells 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 was also studied. The potential yield and quality of bioethanol were studied. The reusability of immobilized cells was also studied. The application of immobilized cells in the separate or co-immobilized way was able to yield bioethanol more efficient. The co-immobilization of S. cerevisiae and A. niger made the process simpler, inexpensive, and less energy due to its less sequential process and the ability of the cell to reuse.
