An Acidithiobacillus ferrooxidans strain WZ-1 (GenBank sequence number: JQ968461) was used as the research object. The effects of Cl-, NO3-, F- and 4 kinds of simulated inorganic anions leaching solutions of electroplating sludge on the bioactivity of Fe2+ oxidation and apparent respiratory rate of WZ-1 were investigated. The results showed that Cl-, NO3(-)- didn't have any influence on the bioactivity of WZ-1 at concentrations of 5.0 g x L(-1), 1.0 g x L(-1), respectively. WZ-1 showed tolerance to high levels of Cl- and NO3- (about 10.0 g x L(-1), 5.0 g x L(-1), respectively), but it had lower tolerance to F- (25 mg x L(-1)). Different kinds of simulated inorganic anions leaching solutions of electroplating sludge had significant differences in terms of their effects on bioactivity of WZ-1 with a sequence of Cl-/NO3(-)/F(-) > or = NO3(-)/F(-) > Cl-/F(-) > Cl(-)/NO3(-).
以嗜酸氧化亚铁硫杆菌菌株WZ-1（GenBank序列编号：JQ968461）作为研究对象。研究了Cl-、NO3-、F-以及4种电镀污泥模拟无机阴离子浸出液对WZ-1亚铁氧化生物活性和表观呼吸速率的影响。结果表明，Cl-、NO3-在浓度分别为5.0 g·L-1、1.0 g·L-1时对WZ-1的生物活性没有任何影响。WZ-1对高浓度的Cl-和NO3-（分别约为10.0 g·L-1、5.0 g·L-1）表现出耐受性，但对F-（25 mg·L-1）耐受性较低。不同种类的电镀污泥模拟无机阴离子浸出液对WZ-1生物活性的影响存在显著差异，顺序为Cl-/NO3(-)/F(-)≥NO3(-)/F(-)>Cl-/F(-)>Cl(-)/NO3(-)。
