PCA analysis of ToF-SIMS spectra obtained from residual pine (a, b) and aspen (c, d) after enzymatic treatment. PCA scores (a, c) and loadings (b, d) show that the separation of treatment groups was explained by differences in lignin and polysaccharide ions. Score plots: red triangles control samples (no enzyme), green stars PcoAspen-treated samples, and blue squares PcoPine-treated samples. Loadings plots: red triangles polysaccharide peaks and green stars lignin peaks. Percent values denote the percent of total sample variance described by PC1. Four to eight spectra were acquired for each sample
