Potential effects of bacterial communities on the formation of blooms of the harmful dinoflagellate Prorocentrum after the 2014 Texas City “Y” Oil Spill

In the laboratory, altered bacterial communities (BCs) due to crude oil exposure significantly enhanced the growth rate and yield of Prorocentrum texanum. In addition, oil-degrading bacteria from oil-contaminated sediment after the Texas City “Y” Oil Spill was isolated, and dinoflagellate growth when co-cultured with single bacterial isolates was investigated. This dataset contains the measurements showing the variation and changes in the growth rate of dinoflagellates depending on the bacterial treatment and different experiments. The cell numbers of dinoflagellates were measured by using light microscopy and a flow cytometer.
