From: Bioaccumulation and toxicity of selenium compounds in the green alga Scenedesmus quadricauda
Effect of different selenium concentrations on the growth of Scenedesmus quadricauda. Effect of different concentrations of selenite or selenate on the growth of the wild type (A, B), selenite resistant strain SeIV (C), selenate resistant strain SeVI (D) and selenite/selenate resistant strain SeIV+VI (E) of Scenedesmus quadricauda. Data are presented as means ± S.D. of triplicate experiments.
