Tiny ocean organisms called plankton form the base of marine food webs. They also drive the cycling of carbon and other elements.

Topics

vitamin B1

thiamin

vitamers

Grants
1 known grant, through Dec 2027

What they work on

  1. Measure how much vitamin B1 and related vitamers are released by B1-producing picocyanobacteria and heterotrophic bacteria grown in pure cultures.
  2. Test whether viral infection and bursting of bacterioplankton releases a different amount or mix of B1 and vitamers than release by healthy cells.
  3. Determine how temperature changes B1 and vitamer release and virus-driven release, and link these fluxes to biomass, growth rate and lysis rate.

More about the research

Many of them cannot make vitamin B1 (thiamin) and must absorb it, or related compounds called vitamers, from seawater. Yet scientists know little about where that supply comes from or how a warming ocean might change it.

Why it matters

Ocean models predict how productive the ocean will be and which species will dominate. Data on how B1 is supplied, and how temperature affects that supply, could improve these models. That in turn could inform predictions of how marine food webs and ocean ecosystem health may respond to warming.

Known grants

From NIH and NSF research grants. Labs often have other funding we can't see.
