Progress in ethanol production with lignocellulosic biomass by different recombinant strains

Abstract

Ethanol fermentation with lignocellulosic biomass involves significantly great challenges, owing to lack of industrially suitable microorganisms for converting cellulose hydrolysates into fuel ethanol, which has traditionally been considered as a major technical roadblock to the development of bioethanol industry. Currently, different recombinant strains have been engineered to produce ethanol from lignocellulosic biomass. The greatest successes have been made in the engineering of Saccharomyces cerevisiae and some other bacteria, including Escherichia coli, Klebsiella oxytoca, and Zymomonas mobilis, which provide a basis for constructing industrially suitable engineered strains for cellulose ethanol industrialization. This review summarizes recent progress in this filed, and also prospect it in the Omic era.
