    Abstract

    Knowledge of taxa mediating phosphorus transformation pathways in piggery waste treatment systems is limited. Taxonomic and functional identities of phosphorous-transforming bacteria in model covered anaerobic piggery wastewater treatment systems were identified using single cell-based-methods with fluorescence microscopy and flow cytometry coupled with next generation sequencing. Enhanced plant growth and fertility for soil receiving pelletised piggery compost in combination with a low rate of inorganic phosphorus fertiliser was demonstrated. These findings aid the development of better strategies for recapturing phosphorus during piggery waste treatment and for efficient re-use of phosphorus as a soil amendment.
