Methods for reducing enzyme consumption in second generation bioethanol fermentation in the presence of lignin |
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)-1. 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. |
