Bioethanol Production by Immobilization, Growth Variables, and Co-cultivation of the Yeast Meyerozyma Guilliermondii and the Plant Zea Mays (Sweet Corn)

Abstract

The increasing demand for renewable energy has driven research into bioethanol production. This study explores the use of immobilized Meyerozyma guilliermondii yeast and co-cultivation with Zea mays (sweet maize) to enhance bioethanol yields. Optimal conditions for yeast adhesion to alginate beads and co-cultivation effects on ethanol production were investigated. Variables such as alginate concentration, bead size, temperature, pH, and nutrients were adjusted to maximize yeast viability and sugar availability. Co-cultivation demonstrated synergistic benefits, significantly improving bioethanol output compared to traditional methods. This approach offers sustainable, efficient bioethanol production with promising environmental and economic advantages.
