Production Process of Bioethanol Fuel Using Supported Saccharomyces Cerevisiae Cells

A new immobilization process of Saccharomyces cerevisiae cells with calcium alginate and coating with solubilized chitosan in citric acid solution was developed. The biocatalyst is used in fermentation processes to produce bioethanol fuel through the use of carbon sources such as glucose, sugarcane juice, and corn hydrolysate, which provided very good yields of productivity (71.3–88.7%) and shows excellent biocatalyst stability during all production processes.
