Figure 2

Growth of three Pseudomonas strains on differing organic phosphorus (P) compounds as a sole P source (100 μM) using succinate (20 mM) as the carbon source. Results shown are the mean of triplicate cultures. The dashed black line indicates approximate OD600 at T = 0. The dashed grey line segregates the positive and negative controls to the organic P treatments. Asterisks denote a significant (T-test, P < 0.05) reduction in growth rate (Fig. S5). Error bars denote standard deviation. Abbreviations: −P, no added orthophosphate; +P 100 µM orthophosphate added; Pch, phophorylcholine; G3P, sn-glycerol-3-phosphate; GPC, glycerolphosphorylcholine; DSM4166, P. stutzeri DSM4166; SBW25, P. fluorescens SBW25; BIRD-1, P. putida BIRD-1; WT, wild type; ΔglpQ, mutant genotype for the secreted glycerolphosphodiesterase; ΔphoBR, mutant genotype for the master regulator of the phosphate starvation response network; ΔphoX, mutant genotype for alkaline phosphatase.
