Total mass and % solubilization of lignin, cellulose, and non-cellulosic sugars from solid residues remaining after CBP fermentation of 5.68 g starting milled poplar biomass. Data are mg recovered from the starting biomass, mg recovered from the solid residues, or % solubilized, as indicated. A Mass (mg recovered) of total lignin, cellulose, and non-cellulosic sugars in the solid residues. These data are from Figs. 4, 5 and 6. B Mass (mg recovered) of total non-cellulosic sugars (Xyl, Glc, Man, Ara, Gal, Rha, Fuc, GalA, GlcA) in the solid residues at the times indicated. The mass of total monosaccharide is from data from Fig. 6. C Mass (left) and percentage (right) of non-cellulosic sugars, cellulose and lignin solubilized by C. thermocellum. All solubilization calculations were done based on the starting biomass. D Mass change and percentage of mass change of net non-cellulosic sugars solubilized by C. thermocellum. Both mass and percentage values are calculated as described in Table 1. The 24 h and 48 h % net solubilization values from starting biomass are 24 h: Glc (13%), Gal (4%), Man (12%), GalA (50%), GlcA (3%), Xyl (7%), Fuc (10%), Rha (− 12%), Ara (− 2%). 48 h: Glc (17%), Gal (9%), Man (21%), GalA (54%), GlcA (4%), Xyl (9%), Fuc (0%), Rha (− 16%), Ara (2%)
