Presented paper reports the possibility of utilization of microbial solubilization process of renewable phosphorus resources for production of phosphorus biofertilizers. The aim of this work was to find the effectiveness of the solubilization process in the relationship with the used material that undergoes the solubilization, that was performed by soil bacteria Bacillus megaterium. Three from four, used materials are recognized as a renewable, such as poultry bones, fish bones as well as ashes from incineration of waste sludge form III stage of biological treatment of wastewater. It was found that the composition of produced acids is strongly related with the material used as a source of phosphorus. The soluble P2 05 concentration in the medium ranged between 68.9 and 1289 mg/L with variations among different sources of phosphate used in the experiment. The highest maximum P205 concentration was found for poultry bones and fish bones 1299 mg/L and 955 mg/L, respectively. (C) 2016 Elsevier B.V. All rights reserved.
