Phosphate requirements for L. crescens growth using phosphate levels found in phloem of citrus cultivars [11]. L. crescens was grown to exponential phase in Hi-GI at 250 rpm, 28 °C (OD600~0.7–0.8, Fig. 16) and washed with a sterile ACES-KOH buffer pH 6.5 prior to inoculation in the M15 medium, pH 5.92. Best growth of L. crescens was observed in 10 mM and 11.69 mM (M15 control) concentrations of monosodium phosphate. I) Cell growth represented as optical density. II) Cell growth in Logarithmic (log2) scale of the optical density
