EVALUATION OF BIOETHANOL PRODUCTION FROM RICE HUSKS USING DIFFERENT YEASTS ISOLATES
Abstract
The increasing demand for renewable energy sources has led to growing interest in bioethanol production from agricultural waste. This study focuses on the evaluation of bioethanol production from rice husks using different yeast isolates. Rice husks, an abundant agro-waste, were subjected to hydrolysis to release fermentable sugars. The hydrolysate was then inoculated with various yeast strains, including Saccharomyces cerevisiae and other locally isolated wild yeasts, under controlled fermentation conditions. Bioethanol yield was quantitatively analyzed using standard distillation and spectrophotometric techniques. Results indicated variations in ethanol production efficiency across the different yeast strains, with Saccharomyces cerevisiae showing the highest yield. The study highlights the potential of rice husks as a low-cost, sustainable feedstock for bioethanol and underscores the significance of yeast strain selection in optimizing fermentation processes. These findings contribute to the advancement of biofuels homologies and waste-to-energy initiatives.
