  As a proof of principle, we demonstrate that even at low concentrations of the phosphate rock, 1% w/v, the bacterial culture is unviable and biological activity is not observed during the singlestep process. On the other hand, in our method, the bacteria are grown without the rock, ensuring high acid production.

  Phosphorite, or phosphate rock, is a kind of igneous or sedimentary rock in which a high amount of phosphate presents as fluorapatite (Ca 5 (PO 4) 3 F), or as hydroxystalline (Ca 5 (PO 4) 3 OH). In the current practice of the phosphate industry, phosphorite is usually upgraded from natural phosphate ore, and then the phosphate concentrate is input to an industrial process, named a wetprocess ...

  Process of rock phosphate solubilization by Aspergillus .

  The process was influenced by the presence of various concentrations of local loess (red soil). The simultaneous occurrence, in our experiment, of high levels of solubilized phosphate and synthesized citric acid, together with the lowest reached pH values, confirmed the role of citric acid in the phosphate solubilization mechanism.
