Solubilization data from three feedstocks, six biocatalysts, and including both time-course and end-point measurements. Results are expressed as mean (n ≥ 2) a Xylan and glucan solubilization. b Fractional carbohydrate content of residual solids after various extents of solubilization. Data were compared to derived equations for two hypothesis (1) Equal fractional solubilization of carbohydrate and non-carbohydrate (dashed lines); (2) Non-carbohydrate fraction is inert (solid lines). The three lines for each model result from different initial carbohydrate compositions of the feedstocks
