Phosphate-solubilizing activities of the mineral PSB strains and pH in the media. (a) Ca3(PO4)2 as mineral phosphate source, (b) FePO4 as mineral phosphate source, and (c) AlPO4 as mineral phosphate source. Error bars = S. (D). Lowercase letters above the bars indicate significant differences of the PS activities of different isolates and the media pH values at P < 0.05 level, respectively
