The distribution of cultivable organic phosphate solubilizing bacteria(OPB) and inorganic phosphate solubilizing bacteria(IPB) in the sediment of Dishui Lake and its diversion rivers was studied in 2010.Results showed that the annual average values of OPB and IPB in sediment of diversion rivers in front of the inlet gate were(2.76×104±1.31×104) and(7.19×l03±3.98×103) CFU·g-1, respectively;while in rivers after the gate they were(1.05×104±3.56×103) and(2.54×l03±8.77×102) CFU·g-1,respectively.The annual values of OPB and IPB in sediment of Dishui Lake were(6.69×103±2.63×103) and(1.66×103±5.83×102) CFU·g-1, respectively.In both Dishui Lake and its diversion rivers,close correlations were observed between OPB(or IPB) amount in sediment and phosphorus concentration in water.OPB or IPB amount had a significantly positive relationship with total phosphorus(TP),and the related coefficients were higher than those with bacteria,total dissolved phosphorus(TDP),and reactive phosphorus(AP).
