  • Method for extracting phosphorous from solids using active leaching and phosphate-accumulating microorganisms
    Patent number: 9005956
    Abstract: The present invention relates to a method of selectively obtaining phosphorus from solids containing heavy metals and phosphate. In this method, the solid is treated under acidic aerobic conditions using microorganisms comprising leaching microorganisms and polyphosphate-accumulating microorganisms, so that the heavy metals and the phosphates are released from the solid and the released phosphates may be taken up by the polyphosphate-accumulating microorganisms. The phosphorus-enriched biomass that is obtained in this manner is separated and may be utilized, e.g., as organic fertilizer.
