Progress and strategies on bioethanol production from lignocellulose by consolidated bioprocessing (CBP) using Saccharomyces cerevisiae

Abstract:

Ethanol production from lignocelluloses of consolidated bioprocessing (CBP) is a system in which cellulase and hemicellulase production, substrate hydrolysis, and fermentation are combined or partially combined by ethanologen microorganisms that express cellulolytic or hemicellulolytic enzymes or engineering cellulolytic microorganisms with ethanol production properties. Due to its potential for significant cost reduction, CBP is receiving more and more attention. In this review article, we discuss the factors that influence the expression level of cellulases in Saccharomyces cerevisiae and updated progress in bioethanol production from lignocellulose by the CBP strategy using the yeast species.
