Evaluation of Unstructured Kinetic Models for the Production of Bioethanol from Banana and Pineapple Wastes

Abstract

Bioethanol is a renewable energy source, and its production from agricultural wastes, such as banana and pineapple peels, is an economical approach. Enzymatic hydrolysis experiments were performed using a simultaneous saccharification and co-fermentation (SSCF) method. Banana and pineapple wastes inoculated with Aspergillus terreus and Kluyveromyces marxianus produced the maximum ethanol concentrations of 0.35 g/L and 0.27 g/L, respectively. Furthermore, logistic unstructured and incorporated models described well the growth of microorganism, product formation, and substrate utilization during SSCF system with high R2 and low RMSD.
