Abstract
Provided are methods of liquefaction, saccharification and fermentation of pre-treated lignocellulosic biomass in production of bioethanol. Addition of PEG or surfactant is effective to enhance cellulase hydrolysis yields at high dry matter (>20%) at surprisingly low concentrations compared with comparable results in low dry matter hydrolysis. This effect is most pronounced at comparatively low cellulase loading <7 FPU (g DM). At high dry matter content, cellulase enzyme consumption can be reduced, without loss of hydrolysis yield, by addition of small quantities of PEG or surfactant.
