Cell recycle batch fermentation of high-solid lignocellulose using a recombinant cellulase-displaying yeast strain for high yield ethanol production in consolidated bioprocessing

► Cell recycling significantly reduces costs associated with inoculum preparation. ► Two-phase separation enabled cell recycling fermentation of lignocellulose. ► Cell-surface engineering successfully improved ethanol yield. ► Ethanol yield through the repeated batch fermentation was 86.3% of theoretical.
