Abstract

This article describes the yeast strains, enzyme preparations, and mineral components used to optimize the nutrient medium composition in bioethanol production through the processing of grape waste. Methods for obtaining second-generation biofuels are among the most relevant topics of modern research. The production of biofuel from food waste helps address two major issues simultaneously. First, it reduces the negative environmental impact by utilizing food waste. Second, considering the growing demand for energy resources driven by economic and demographic growth, it serves as a renewable energy source. In this study, the nutrient medium composition was optimized, and experimental results demonstrate an increase in bioethanol yield during the alcoholic fermentation process.
