Phenotype of BJ5465.sfp.bpsA grown on solid media containing glucose or glycerol. a Colony color intensity of BJ5465.sfp.bpsA spotted on plates containing rich media and 2% glucose or the non-fermentable carbon source glycerol after 3 days and 7 days of growth. Colony color intensities are quantified using the Fiji image processing package distribution of ImageJ [45] and are normalized to highest detected colony intensity after brightness adjustment of the background. Error bars represent the standard deviation of 3 replicates. Representative colonies are shown in the panel below the graph. Pictures of the full plates can be found in Additional file 1: Figure S2. b Bright field microscopy of cells grown on the non-fermentable carbon source glycerol after 3 days and 7 days, %blue represents the percentage of pigment producing cells of 500 cells counted for each condition, ×63 magnification, scale bar = 10 µm
