Response of the 28 C. reinhardtii strains reported in Table 1 to a 100 nM concentration of atrazine (A), terbuthylazine (B), and diuron (C) (n = 3). Cell cultures at early mid-exponential phase (Abs₇₅₀ = 0.5 O.D., 10⁶ cells/mL, and 5 µg/mL chlorophyll content) grown under 50 μmol m⁻² s⁻¹ continuous light at 25 °C and continuous stirring at 150 rpm (n = 3)
