Patent ID: 8691551

Claim:
A process for producing phosphate from an organic material, wherein the organic material comprises bone suitable for extraction of phosphates, comprising: (a) fermenting the organic material in a medium in the presence of at least one microorganism, wherein the fermenting is under conditions, and for a sufficient period of time, to produce a fermentation product; (b) treating solids of the fermentation product with acid, in a medium to solubilize phosphates from the fermentation product, wherein the solids of the fermentation product comprises the bone suitable for extraction of phosphates; (c) separating a liquid phase from the acid treated fermentation product; (d) admixing a reagent comprising NH 4 + and/or a reagent comprising Mg 2+ ions into the separated liquid phase in a sufficient amount and for a period of time sufficient to precipitate solubilized phosphates from the separated liquid phase; and (e) recovering the precipitated phosphate.
