Total combined sugar (glucan plus xylan) release from Stage 1 (pretreatment, designated as “PT”) and Stage 2 (7 days of C. thermocellum consolidated bioprocessing, designated as “CBP”) for solids resulting from hydrothermal (HT), dilute acid (DA), dilute alkali (Alk), and co-solvent-enhanced lignocellulosic fractionation (CELF) pretreatments at conditions that gave the highest total sugar release. Pretreatments were performed at 10% solids loading (80 g switchgrass on a dry basis) with a total reaction mass of 800 g. CBP was performed at a 0.5 wt% glucan loading of all substrates with a working mass of 50 g
