From: The impacts of pretreatment on the fermentability of pretreated lignocellulosic biomass: a comparative evaluation between ammonia fiber expansion and dilute acid pretreatment

Figure 4

Sugar consumption after 24 h of fermentation in yeast nitrogen base (YNB)-supplemented wash streams from dilute acid pretreatment at different solids loading (5%, 7.5%, 30% (Sund)) and ammonia fiber expansion (AFEX) pretreatment in wash stream at 7.5% solids loading equivalent (a, c) and 15.0% solids loading equivalent (b, d). Fermentation was conducted in 24-well microplates at 2.0 mL working volume with an initial cell density of 0.1 unit of optical density (OD) 600 nm. Initial glucose and xylose was 9 ± 1 g/L and 35 ± 2 g/L, respectively.
