能够对铁离子进行有氧呼吸的细菌分布在真细菌和古细菌门中。比较光谱分析显示，系统发育上不同的生物在可溶性铁的自养生长过程中表达了大量光谱上不同的氧化还原活性生物分子。氧化亚铁硫杆菌、氧化亚铁钩端螺旋体、热硫酸氧化亚铁硫杆菌和塞杜拉金属藻分别具有由一种蓝色铜蛋白、一种新型红色细胞色素、一种新型黄色蛋白和一种新型黄色细胞色素主导的铁呼吸链。有必要对每种呼吸链进行进一步调查，以推断出每种呼吸链的优缺点。
Bacteria capable of aerobic respiration on ferrous ions are spread throughout eubacterial and archaebacterial phyla. Comparative spectroscopic analyses revealed that phylogenetically distinct organisms expressed copious quantities of spectrally distinct redox-active biomolecules during autotrophic growth on soluble iron. Thiobacillus ferroxidans, Leptospirillum ferrooxidans, Sulfobacillus thermosulfidooxidans, and Metallosphaera sedula possessed iron respiratory chains dominated by a blue copper protein, a novel red cytochrome, a novel yellow protein, and a novel yellow cytochrome, respectively. Further investigation of each type of respiratory chain will be necessary to deduce the advantages and disadvantages of each.
