A gene expression study evaluated how deletion of a gene encoding a high-affinity phosphate transporter (Δpst) affects growth of E. coli at 37°C in minimal medium buffered to pH 7.4. Cultures were grown with either low inorganic phosphate (Pi; 0.05 mM) or high Pi (5 mM). Exponential-phase growth rates (μ, h−1) were calculated from OD600.
Which condition best supports the observed growth pattern?
