We propose a new process of unified aerobic delignification and anaerobic saccharification and fermentation of wood by a single microorganism, the white-rot fungus Phlebia sp. MG-60. This fungus is able to selectively degrade lignin under aerobic solid state fermentation conditions, and to produce ethanol directly from delignified oak wood under semi-aerobic liquid culture conditions. After 56 d aerobic incubation, 40.7% of initial lignin and negligible glucan were degraded. Then under semi-aerobic conditions without the addition of cellulase, 43.9% of theoretical maximum ethanol was produced after 20 d. Changing from aerobic conditions (biological delignification pretreatment) to semi-aerobic conditions (saccharification and fermentation) enabled the fermentation of wood by solely biological processes. This is the first report of ethanol production from woody biomass using a single microorganism without addition of chemicals or enzymes. (C) 2012 Elsevier Ltd. All rights reserved.
