Bioethanol production from sugar beet molasses and thick juice using Saccharomyces cerevisiae immobilized on maize stem ground tissue

► Sugar beet molasses and thick juice as raw materials for bioethanol production. ► Saccharomyces cerevisiae is immobilized on maize stem ground tissue as new carrier. ► Using this new biocatalyst for fermentation, a superior system was realized. ► Bioethanol fermentation under normal and very high gravity conditions was studied. ► Thick juice was found to be economically favorable, compared to molasses.
