Growth and MCPA mineralization by C. pinatubonensis AEO106 under exposure to 0–50 μM CuSO₄. a Growth measured as optical density at 600 nm. b Mineralization of ¹⁴C–MCPA measured as accumulation of ¹⁴C–CO₂ compared to total amount of ¹⁴C–MCPA added to the cultures. Data are mean values from triplicate cultures from one representative experiment (the experiment was repeated twice). Error bars represents standard error of means
