铁的存在既是一种营养物质，也是一种电子受体，它的存在被证明对饮用水中的大肠杆菌有利。在初始铁浓度较低的水中加入少量的硫酸亚铁，可显著增加大肠杆菌的数量。在厌氧条件下，水中氧化铁的存在增加了细菌的培养能力。
The presence of iron, used both as a nutrient and as an electron acceptor, was demonstrated to give an advantage to Escherichia coli bacteria in drinking water. Slight additions of ferrous sulfate to water with initial low iron concentrations led to a significant increase in the number of E. coli bacteria. The presence of ferric oxide in water under anaerobic conditions increased bacterial cultivability.
