Fig. 2From: Engineering of global transcription factor FruR to redirect the carbon flow in Escherichia coli for enhancing l-phenylalanine biosynthesisHeat maps of cell growth (OD610) and fluorescence intensity (MFU) of the selected mutants. A total of 276 samples in each well are presented as single colonies (a, b, and c). A total of 9 samples in H10-H12, P10-P12, and Z10-Z12 wells are presented as the controls: PHE01. The cells were cultured with fermentation medium in a 96-deep well plateBack to article page
