A 2.9-fold ethanol yield increase in the consolidated bioprocessing of high S/G Populus biomass over the low S/G variant (top); biomass-derived acetate (below, dotted line) measured in un-inoculated bioreactor controls and total acetate measured in CBP bioreactors (below, solid line)—fermentative acetate is approximately the difference between these two series. Mean values and standard deviations are shown for triplicate fermentations
