Polyphosphate accumulation in microalgae and cyanobacteria: recent advances and opportunities for phosphorus upcycling.. Curr Opin Biotechnol. 90. (pp. 103207-).0958-1669https://mro.massey.ac.nz/handle/10179/71862Phosphorus (P) must continuously be added to soils as it is lost in the food chain and via leaching. Unfortunately, the mining and import of P to produce fertiliser is unsustainable and costly. Potential solutions to the global issues of P rock depletion and pollution lie in microalgae and cyanobacteria. With an ability to intracellularly store P as polyphosphates, microalgae and cyanobacteria could provide the basis for removing P from water streams, thereby mitigating eutrophication, and even enabling P recovery as P-rich biomass. Metabolic engineering or changes in growing conditions have been demonstrated to improve P removal and recovery by triggering polyphosphates synthesis in the laboratory. This now needs to be replicated at full scale.(c) 2024 The Author/sCC BY 4.0https://creativecommons.org/licenses/by/4.0/Journal article10.1016/j.copbio.2024.1032071879-0429journal-article103207-https://www.ncbi.nlm.nih.gov/pubmed/39303380103207S0958-1669(24)00143-5
