As shown in Fig. 2, parameters of mmax and Ks were calculated from algae growth based on nitrate concentrations of 6.0, 12.0, 18.0, and 24.0 mg/L by Monod equation. The experiment data shown in
Fig. 1aed were used to determine the kinetic model parameters using Monod equation. The values of mmax and Ks of I. galbana were calculated at 0.23 h1 and 1.16 mg/L (R2 ¼ 0.90), respectively. Parameters of mmax and Ks of N. oculata, D. salina and D. tertiolecta showed 0.17 h1 and 4.48 mg/L (R2 ¼ 0.93), 0.13 h1 and 6.92 mg/L
