The current state and ways to improve the production of bioethanol from grape pomace using yeast Saccharomyces cerevisiae

Jamalov Zohid Zafarovich, Kemalov Ruslan Alimovich

Bioethanol production from agricultural waste is an alternative to fossil fuels. Grape pomace is the most common sediment in the world, including in Uzbekistan. Whether strong yeast with high resistance to inhibitors is necessary for the production of lignocellulose bioethanol is still unknown. It has been established that these stressors significantly hinder the growth of crops and the productivity of fermentation. Due to the limited amount of nutrients, exposure to sunlight, temperature fluctuations and low acid and ethanol content, grape by-products were chosen as an extreme environment for the search for strong natural yeast. A bio-processing plant for the processing of grape by-products can become a short-term solution for the clean, efficient and cost-effective production of bioethanol and value-added products.
