Effects of augmenting the 20 μg/mL cellulase treatment with BSA or with xylanase (xyl). Panels A-E show results of a two-curve MCR model of extracted red spruce and panels F-J show results of a two-curve MCR model of unextracted red spruce. Scores (A,C,F and H) show the position of each sample on a continuum between the control and the 100 μg/mL cellulase treatment. In loadings plots (B,D,G and I) lignin-related peaks are denoted by red triangles, protein-related peaks by green stars, and polysaccharide-related peaks by blue squares. In panels E and J, the ratios of the scores are calculated to provide a polysaccharide peak fraction (note that this is a different method than taking a ratio of raw peak intensities). Error bars represent one standard deviation (n = 9).
