Differences in K. pneumoniae YT-9 metabolites between iron-supplemented (Fe) and control (LB) groups based on LC-MS positive ion mode (left) and negative ion mode (right) analyses. A PLS-DA of the intracellular metabolome, each data point representing an individual sample. B Heatmaps of the differential metabolic production (DMP) in the intracellular metabolome. C KEGG analysis of the DMP-enriched biological processes
