Figure 2. Response of various phytoplankton species in culture study.

Variation of in vivo fluorescence of 12 marine phytoplankton species upon H₂O₂ addition at 0 (control, solid line) and 1.6 mg L⁻¹ (treatment, dashed line). A) Aureococcus anophagefferens (Aa) and prasinophyte Micromonas pusilla (Mp). B) Diatoms Phaeodactylum tricornutum (Pt), Minutocellus polymorphus (Mpo), Skeletonema costatum (Sc), Thalassiosira pseudonana (Tp) and Thalassiosira weissflogii (Tw). C) Chlorophyte Dunaliella tertiolecta (Dt). D) Prymnesiophytes Isochrysis galbana (Ig) and Emiliania huxleyi (Eh). E) Dinoflagellates Amphidinium carterae (Ac) and Prorocentrum micans (Pm). Vertical error bars are deviations between duplicate cultures.
