Panel A shows a purple gradient heatmap of carbon sources utilization by bacterial strains, with intensity values from zero to over two hundred. Hierarchical clustering groups rows and columns based on similarity. Panel B presents a green-to-red gradient heatmap of chemicals and antibiotics, measuring responses of bacteria on a scale from zero to one, with clustering applied to rows and columns. Both panels include dendrograms and color scales indicating data values. — Heatmaps showing (A) the utilization of carbon sources and (B) the results of chemical sensitivity tests for the three Pseudomonas species. Metabolic activity on carbon sources is expressed in Biolog units (BU), with higher absorbance values indicating greater metabolic activity. Sensitivity test results are normalized on a scale from 1 (green, growth comparable to the positive control) to 0 (red, no growth in the presence of the tested compound).
