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

Figure 3

Cell density of (a) Saccharomyces cerevisiae 424A(LNH-ST) and (b) Escherichia coli KO11 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. 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. The solids-loading equivalent of the wash streams tested was 7.5% and 15.0%.
