Nine different media containing three different nitrogen sources, concentration of carbon source (cassava starch hydrolysate), and the pH were run in shake flasks to produce bioethanol using Saccharomyces cerevisiae. Analysis of variance of the results from the shake flask showed that there was no significant difference (P > 0.05) in the maximum concentration of ethanol (Pt) produced from the media. From the bioreactor studies, similar kinetic parameters, including Pt of 48.16 g/L with theoretical yield (Yetoh) of 92% and Pt of 47.13 g/L with Yetoh of 92%, were recorded from 100 g/L carbon source in the complex and minimal media, respectively. ©Taylor & Francis.
