Dataset: ESP 2014 DMSP
Deployment: Moran_Monterey_2014

Glycine betaine, an inhibitor of bacterial DMSP uptake, was added at 5 micromolar concentrations to triplicate samples; triplicate controls had no addition. Subsamples were removed at the initial time point and at 2 hr intervals up to 6 hrs. Samples were analyzed for remaining DMSPd and the difference between glycine betaine and control incubations was calculated to estimate DMSP consumption rate.
