文摘

A fundamental exploration on fluoride tolerance of A. ferrooxidans was performed. The Fe2+-grown A. ferrooxidans presented higher fluoride tolerance than the S0-grown one. The fluoride tolerance of A. ferrooxidans was associated with the Fe3+ concentration. The reaction between Fe3+ and F− could significantly reduce the toxicity of fluoride.
