One hyndred sixty-eight bacterial isolates from the rhizoplane and rhizosphere (2mm-10mm away from the root surface) of cupuacu were isolated in spring 1997 in an experimental polyculture site (SHIFT ENV-23) near Manaus and their capacity to grow on media with poorly soluble AlPO4 was determined. 75% of the isolated bacteria were found to be effective in solubilizing hardly-soluble AlPO4 and FePO4. Two strains were selected because of their ability to solubilize high amounts (>50ug P/ml) of AlPO4 and FePO4 in former experiments. Their capacity to solubilize inorganic phosphates was investigated in liquid culture. Both strains solubilized similar amounts of P. The amount of P solubilization was highest after three days of growth while cell numbers were maximal after 13 days. During the solubilization process one strain show a decrease in pH while the other strain increased the pH. This incates that the solubilization of inorganic phosphates is not necessarily related to the acidification. |
