Response Surface Optimization of Bioethanol Production from Sugar Bagasse by Aspergillus flavus

Abstract

Sugarcane bagasse presents an appealing opportunity as a bioethanol source due to its abundance, affordability, and renewable characteristics. Employing response surface methodology to optimize operational parameters affecting bioethanol production from sugarcane bagasse offers a cost-effective and efficient approach to enhance bioethanol yields. In this investigation, sugarcane bagasse served as the substrate for bioethanol production, with the microbial strain Aspergillus flavus being utilized. The study aimed to explore the impacts of temperature, pH, and inoculum concentration on bioethanol yield through a central composite design. The findings revealed that the optimal conditions for bioethanol production were observed at a temperature of 26°C, pH of 6, and substrate concentration of 50 g/L. Consequently, the projected bioethanol yield under these conditions reached 36.4 g/L. These results contribute valuable insights into the potential of sugarcane bagasse as a bioethanol feedstock, emphasizing the significance of optimizing process parameters to maximize yields. It is evident from this study that the optimization of process parameters plays a critical role in enhancing bioethanol yield from sugarcane bagasse. Furthermore, the study showcases the effectiveness of utilizing Aspergillus flavus as a microbial strain for bioethanol production.
