Metabolomic analysis of in vitro degradation of maize particles by two microbial consortia. PCA score plot of metabolic profiles in (A) positive and (B) negative ionization modes. Colored circles represent the metabolic profiles of individual samples. Ellipses indicate 95% confidence region for each group. Relative metabolite levels of maize cellulolytic degradation by two bacterial isolates in (C) positive and (D) negative ionization modes. The color scale shows levels for each metabolite relative to the average abundance. Asterisks indicate significant differences (P < 0.05) between each group. Summary statistics are provided in Supplementary Table 7.
