Johnson Lab travels to Knoxville to study Prochlorococcus C and N metabolism

Erik Zinser and Sarah Loftus at UTK Diel 2013The Johnson Lab traveled to Knoxville, TN to work with our collaborators in the Zinser Lab (University of Tennessee Knoxville), on an experiment to investigate the carbon and nitrogen metabolism of Prochlorococcus.  Using both traditional carbon uptake techniques through advanced metabolomics approaches, the experiment was designed to quantify how Prochlorococcus, the most abundant marine phytoplankton, internally processes carbon and nitrogen, the building blocks of life. This information will shed light on the role Prochlorococcus has in modulating the carbon and nitrogen cycles of the ocean, and how this role may change as the ocean environments evolve.
