Figure 5From: The impacts of pretreatment on the fermentability of pretreated lignocellulosic biomass: a comparative evaluation between ammonia fiber expansion and dilute acid pretreatmentTime course of fermentation of wash stream from 7.5% solids loading equivalent of ammonia fiber expansion (AFEX) and dilute acid pretreated corn stover. Fermentation was initiated at 0.1 unit optical density (OD) 600 nm and the wash streams were supplemented with 1 g/L yeast extract and 2 g/L peptone.Back to article page
