Enhanced cellulosic ethanol production by increasing p-benzoquinone tolerance of Saccharomyces cerevisiae in adaptive evolution.
p-Benzoquinone, a lignin-derived inhibitor generated during lignocellulosic biomass pretreatment, severely restricts microbial fermentation and remains a major obstacle to efficient cellulosic ethanol production. In this study, p-benzoquinone concentrations in different lignocellulosic hydrolysates ranged from 130 to 2...
