Optimization of conditions for ethanol production from sugarcane molasses by fermentation with Saccharomyces cerevisiae cells immobilized on cotton gauze

Year: 2025

Type: article

Abstract: In order to obtain an efficient and convenient technology for immobilizing Saccharomyces cerevisiae cells on cotton gauze to improve the efficiency of ethanol production from sugarcane molasses by fermentation, the S. cerevisiae GJ08 cells was immobilized on cotton gauze in this study, the seed liquid was inoculated into sugarcane molasses for fermentation to produce ethanol, and the effects of inoculum, culture time, gauze size and amount, and ventilation volume on ethanol yield were investigated. The results showed that the optimum conditions for ethanol production from sugarcane molasses fermentation were as follows: inoculum 17.5%, culture time 10 h, gauze size 1 cm×1 cm, gauze dosage 15 g/L, ventilation volume 100 mL/min. Under the optimal conditions, the ethanol yield reached 104.22 g/L, which was 30.85% higher than that before optimization. The research results provided technical support and theoretical basis for the fermentation of sugarcane molasses to produce ethanol.
