| الوصف: | In this work, Platymonas helgolandica was used as an experimental material to study the effect of chromium on it. Under the experimental ecological condition, the concentrations of Cr (VI) were set as 0, 0.05, 0.1, 1, and 10 mg/L. Every concentration designed with three parallel groups. The ecotoxicology method was used to investigate the impact of Cr (VI) on P. helgolandica, and (EC50) was calculated by the method of linear interpolation. The results showed the growth of P. helgolandica had a more obvious “Hormesis” when chromium was 0.05 mg/L. However, with Cr (VI) increased, the inhibition on P. helgolandica was increasing, and the cell density of P. helgolandica decreased. The EC50 achieved at 24 h, 48 h, and 72 h revealed that the relative growth rate had a downward trend over time. The remodified Logistic model, the modified Gompertz model, and the Logistic model were suitable to describe cell density in an operating cycle and were beneficial to explore the growth of P. helgolandica. |
