This three-year, $378,208 National Science Foundation project grant supports research into polyphosphate production and cycling in marine ecosystems through the Geosciences program (CFDA 47.050). The University of California San Diego Scripps Institution of Oceanography will assess the total content and chain length distribution of polyphosphate across microbial groups and environmental conditions in the Pacific Ocean and Mediterranean Sea. Researchers will apply a new phosphorus-targeted mass spectrometry method to resolve polyphosphate content and speciation at an unprecedented level of detail. By combining cell sorting with elemental, biochemical, and radiotracer analyses, the team aims to further the mechanistic understanding of polyphosphate physiology and cycling in the ocean. Outcomes include advancing polyphosphate research across disciplines and supporting postdoctoral, graduate, and undergraduate students in marine science.
