Continuous ethanol fermentation by immobilized yeast cells in a fluidized‐bed reactor

Abstract

Abstract Continuous alcoholic fermentation of untreated crude sugar beet molasses has been studied. The process was carried out in a vertical fluidized‐bed reactor with beads of calcium‐alginate containing immobilized Saccharomyces cerevisiae . The influence of hydraulic residence time, concentration of substrate and other variables have been studied.
