Abstract	Four strains (Enterobacter sp. EnHy-401, Arthrobacter sp.ArHy-505, Azotobacter sp.AzHy-510 and Enterobacter sp.EnHy-402) which have the ability to solubilize tricalcium phosphate (TCP) were used to study the mechanism of P-solubilization. It was found that three phosphate solubilizing bacteria (EnHy-401, ArHy-505 and AzHy-510) producing exopolysaccharide (EPS) have a stronger ability for P-solubilization than isolate EnHy-402 without EPS production, of those, the strain EnHy-401 with the highest EPS production and efficient organic acids on P-solubilization had a stronger capacity for P-solubilization than the others. Further studies demonstrated that addition of EPS into medium could increase the amount of phosphorus solubilized by organic acid, but failed to release phosphorus from TCP alone. The synergistic effects of EPS and organic acid on TCP solubilization varied with the origin and the concentration of EPS in medium. EPS produced by EnHy-401 was most effective in promoting phosphorus release at an optimal concentration in medium. The increase of P-solubilization brought by EPS attributed to the participation of EPS led to the change in homeostasis of P-solubilization, pushing it towards P dissolved by holding free phosphorus in the medium, consequently resulting in greater phosphorus released from insoluble phosphate. We therefore suggest that EPS with ability of phosphorus-holding may be a novel important factor in the microbial dissolution of TCP except for organic acid.
