Dataset: Dimethylsulfoniopropionate (DMSP) concentrations and turnover during a deployment of the Environmental Sample Processor in Fall, 2014 in Monterey Bay, CA

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.
