Abstract

This abstract describes a study of efficiency immobilized yeasts usage in the fermentation of sugar-based raw materials. It was found that the fermentation of molasses wort by yeasts immobilized in sorghum stalks particles provides an increase in the ethanol production rate per gram of biomass per hour, increases the yield of ethanol per ton of raw materials, as well as reduces the fermentation time. It is proved that this technological method could improve the bioethanol production efficiency.
