RIASSUNTO

This paper presents the possibility of producing phosphorus fertilizers through Acidithiobacillus ferrooxidans utilization in secondary raw materials solubilization. Phosphorus was obtained from the bones of poultry and fish as well as from Morocco phosphorite. Four doses of poultry bones and fish bones were used in the experiment (2, 4, 10 and 20 g/L) and two doses (2 and 4 g/L) of phosphorite were also used. The experimenters measured the final pH, which increased in proportion to the increase in the number of poultry bone doses, whereas in the case of fish bones it decreased in proportion to the increase in the number of fish bone doses. Only in the case of phosphorite, where 10 g/L were used, there was a slight increase in pH during solubilization observed. The highest phosphorus concentration of 1.9% (expressed as P2O5) was found for the solubilization performed on fish bones with the highest dose (20 g/L). The formulation obtained in this study meets the necessary requirements for use as a bio-fertilizer because of the relatively low content of P2O5 and the low content of toxic elements. The results confirm the utilization of Acidithiobacillus ferrooxidans in the biosolubilization of phosphorus renewable raw materials that can alleviate the problem of the world’s depleting phosphorite deposits.
