Phosphorus solubilization level represented by presence of PO₄ ^-3 in 0,5 ml of bacteria inoculum (OD₆₀₀ 0.10) in liquid TCP medium. Media were supplemented with 3 different phosphorus concentrations: NoP – blue, LowP – red, HighP – green. Letters indicate significant differences between bacteria for each phosphorus variant.
