The effects of different concentrations of bisphenol A (BPA) on Chlorella vulgaris and removal capacity of BPA by Chlorella vulgaris were investigated. Results showed that a low concentration (0-20 mg x L(-1)) of BPA promoted the growth of Chlorella vulgaris, whereas a relative high concentration (20-50 mg x L(-1)) of BPA inhibited the growth of Chlorella vulgaris, and the inhibition effect was positively correlated with the concentration of BPA. Likewise, a high dose of initial BPA (> 20 mg x L(-1)) led to a decline in the content of chlorephyll a. Chlorella vulgaris had BPA removal capacity when initial BPA concentration ranged from 2 mg x L(-1) to 50 mg x L(-1). There was positive correlation between the removal rate of BPA per cell and initial BPA concentration. The removal rate of BPA was the highest when initial BPA was 50 mg x L(-1), which appeared between lag phase and logarithmic phase.
研究了不同浓度双酚A（BPA）对小球藻的影响以及小球藻对BPA的去除能力。结果表明，低浓度（0 - 20 mg x L(-1)）的BPA促进小球藻生长，而相对高浓度（20 - 50 mg x L(-1)）的BPA抑制小球藻生长，且抑制作用与BPA浓度呈正相关。同样，高剂量的初始BPA（> 20 mg x L(-1)）导致叶绿素a含量下降。当初始BPA浓度在2 mg x L(-1)至50 mg x L(-1)范围内时，小球藻具有BPA去除能力。每个细胞对BPA的去除率与初始BPA浓度呈正相关。当初始BPA为50 mg x L(-1)时，BPA去除率最高，出现在延迟期和对数期之间。
