Bioassays quantifying the lytic capabilities of supernatants from Alexandrium pseudogonyaulax and Alexandrium monilatum on the cryptophyte Rhodomona salina

The cryptophyte Rhodomonas salina was subjected to various concentrations of supernatants of Alexandrium (A. pseudogonyaulax, A. monilatum) for 3 or 24 h. Then, the percentage of intact R. salina cells was quantified microscopically. This dataset comprises all cell counts from the R. salina bioassays used to construct dose-response curves. The experiments were carried out between November 9, 2023 and March 26, 2024 in the laboratories at the Alfred-Wegener-Institute in Bremerhaven, Germany.
