Targeted metabolomics of spent media derived from bioreactor-supported defined microbial ecosystems used in this study. The biplot of the PLS-DA model was generated using mean centered and scaled metabolite concentrations profiled from 1D 1H NMR spectroscopy data. Uninoculated bioreactor medium was also profiled as a control. The plot was generated in R using the ropls (version 1.12.0) and ggplot2 (version 2.2.1; H. Wickham. ggplot2: Elegant Graphics for Data Analysis. Springer-Verlag New York, 2016).
