棕色固氮菌细菌铁蛋白能直接快速地从金属铂电极上得到电子或提供电子给铂电极。经－６００ｍＶ（相对于ＮＨＥ）还原电位处理后，还原态细菌铁蛋白在可见光谱区中（３８０－５８０ｎｍ）所呈现的整体吸收光谱强度明显高于氧化态细菌铁蛋白的吸收光谱强度。经氯化钴处理后的细菌铁蛋白表现出较弱的电极活性及释放铁的速率明显下降。此外，细菌铁蛋白在体外模拟棕色固氮菌整体细胞内的微量氧环境体系中仍有氢还原现象，因而推测细菌铁蛋白在该菌体内也能进行吸氢反应。细菌铁蛋白是一种类似有吸氢氢酶功能的蛋白质
Azotobacter vinelandii ferritin can directly or rapidly obtain electrons from metal platinum electrodes or provide electrons to platinum electrodes. After the reduction potential of -600mV (vs. NHE), the overall absorbance spectrum of the reduced form of the bacterial ferritin in the visible (380-580nm) visible range was significantly higher than that of the oxidized bacterial ferritin. Bacterial ferritin treated with cobalt chloride showed weaker electrode activity and a marked decrease in the rate of iron release. In addition, bacterial ferritin still has hydrogen reduction in the micro-oxygen environment system which mimics the whole cell of Azotobacter vinelandii in vitro. Therefore, it is presumed that bacterial ferritin can also carry out hydrogen-absorbing reaction in this cell body. Bacterial ferritin is a protein that is similar to a hydrogen-absorbing enzyme
