摘要：考察了不同浓度双酚A(BPA)对普通小球藻(Chlorella vulgaris)生长特性的影响,以及普通小球藻生长过程对BPA的去除效能.研究表明,低浓度BPA(0~20 mg·L-1)对普通小球藻生长具有促进作用,而高浓度BPA(20~50 mg·L-1)对普通小球藻生长具有抑制作用,且抑制效应与BPA浓度呈正相关关系.低剂量BPA(<20 mg·L-1)对叶绿素含量并无明显的影响,高剂量BPA(>20 mg·L-1)造成叶绿素含量降低.在BPA初始浓度2~50 mg·L-1的范围内,普通小球藻对其都有一定的去除效能,单位普通小球藻对BPA去除速率与其初始浓度呈正相关关系.BPA投加量为50 mg·L-1时,BPA去除速率最大,且最大速率出现于延滞期与对数期之间.
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·L- 1) of BPA promoted the growth of Chlorella vulgaris, whereas a relative high concentration( 20-50 mg·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·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·L- 1to 50 mg·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·L- 1,which appeared between lag phase and logarithmic phase.
