Sulfate reducing bacteria (SRB) are blamed as main culprits in triggering huge corrosion damages by microbiologically influenced corrosion. They obtained their energy through enzymatic conversion of sulfates to sulfides which are highly corrosive. However, conventional SRB detection methods are complex, time-consuming and are not enough sensitive for reliable detection. The advanced biosensing technologies capable of overcoming the aforementioned drawbacks are in demand. So, nanomaterials being economical, environmental friendly and showing good electrocatalytic properties are promising candidates for electrochemical detection of SRB as compared with antibody based assays. Here, we summarize the recent advances in the detection of SRB using different techniques such as PCR, UV visible method, fluorometric method, immunosensors, electrochemical sensors and photoelectrochemical sensors. We also discuss the SRB detection based on determination of sulfide, typical metabolic product of SRB.

翻页:推进硫酸盐还原菌检测平台及其优势

硫酸盐还原细菌 (SRB) 被认为是微生物影响腐蚀引发巨大腐蚀损害的罪魁祸首。他们通过将硫酸盐酶促转化为具有高腐蚀性的硫化物来获得能量。然而,传统的 SRB 检测方法复杂、耗时且不够灵敏,无法进行可靠检测。需要能够克服上述缺点的先进生物传感技术。因此,与基于抗体的测定相比,经济、环保且显示出良好电催化性能的纳米材料是用于电化学检测 SRB 的有希望的候选者。在这里,我们总结了使用不同技术检测 SRB 的最新进展,例如 PCR、紫外可见法、荧光法、免疫传感器、电化学传感器和光电化学传感器。我们还讨论了基于硫化物(SRB 的典型代谢产物)的测定的 SRB 检测。
