Abstract

Effects of FeS nanoparticles inducing corrosion of iron on the physiological metabolism of sulfate-reducing bacteria (SRB) and the iron corrosion mechanism are remained unanswered. In this paper, the structures and electrical conductivity of biosynthesized FeS (Bio-FeS) and chemically synthesized FeS (Chem-FeS) were compared, and the effect of SRB on the corrosion of 316 L stainless steel with the addition of Bio-FeS, Chem-FeS, riboflavin, and humic acid was studied. The results show that Bio-FeS accelerates the electron transfer in SRB due to its good conductivity. The adhesion of Desulfovibrio bizertensis SY-1 was significantly inhibited, when the concentration of Bio-FeS and Chem-FeS was greater than 20 ppm, Bio-FeS, Chem-FeS, riboflavin and humic acid, accelerates the corrosion of 316 L stainless steel by accelerating the electron transfer process of SRB.

硫酸盐还原菌电子转移增强生物合成FeS纳米颗粒对316 L不锈钢的加速腐蚀

FeS纳米颗粒诱导铁腐蚀对硫酸盐还原菌（SRB）生理代谢的影响及铁腐蚀机理尚不清楚。本文比较了生物合成FeS （Bio-FeS）和化学合成FeS （Chem-FeS）的结构和电导率，并研究了添加Bio-FeS、Chem-FeS、核黄素和腐植酸后SRB对316 L不锈钢腐蚀的影响。结果表明，由于生物- fes具有良好的导电性，加速了SRB中的电子转移。当Bio-FeS和Chem-FeS浓度大于20 ppm时，显著抑制了bizertensis脱硫弧菌sys -1的粘附，Bio-FeS、Chem-FeS、核黄素和腐殖酸通过加速SRB的电子传递过程，加速了316 L不锈钢的腐蚀。
