Turning the Page: Advancing Detection Platforms for Sulfate Reducing Bacteria and their Perks

Abstract

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.

Nanomaterial-Based Label-Free Electrochemical Aptasensors for the Detection of Thrombin

“…Combined with their large surface area, they provide a platform for increasing the density of immobilized aptamers, thus enhancing their sensitivity [28]. Many nanomaterials have excellent conductivity and intrinsic catalytic activity and can therefore act as redox probes without the requirement of additional costly labeling methods [28][29][30][31]. In emphasizing these material merits and their impact on resolving the above-mentioned challenges in thrombin detection, this paper reviews the most recent advances in label-free electrochemical aptasensors for the detection of thrombin, with an emphasis on nanomaterials and nanostructures utilized in sensor design and fabrication.…”

Tuning the Redox Chemistry of Copper Oxide Nanoarchitectures Integrated with rGOP via Facet Engineering: Sensing H2S toward SRB Detection

“…The anaerobic SRB, dominant corrosive microorganisms, exist in various environments including oilfield water and wastewater where they typically metabolize sulfates into sulfides to acquire their energy through this enzymatic reduction pathway . These metabolically produced sulfides during SRB respiration are tremendously toxic and corrosive, which may cause severe environmental and industrial damages . On the contrary, SRB play a crucial role in wastewater purification as well.…”

“…4 These metabolically produced sulfides during SRB respiration are tremendously toxic and corrosive, which may cause severe environmental and industrial damages. 5 On the contrary, SRB play a crucial role in wastewater purification as well. It has been welldocumented that these microbes may possibly be used in removing sulfate and heavy metals from industrial wastewater.…”

Novel Synthesis of Sensitive Cu-ZnO Nanorod–Based Sensor for Hydrogen Peroxide Sensing

“…Zinc oxide has been intensively explored due to its intriguing features, in addition to electrochemical sensors, photoelectric devices, gas sensors, and lithium-ion batteries ( Ding et al, 2018 ). As a result of the superior catalytic properties of zinc oxide nanostructures compared to those of other metal oxide nanostructures, manufacture of low-cost hydrogen peroxide sensors based on ZnO nanostructures grown on conducting copper foil is possible ( Asif et al, 2022b ). Nanocombs, nanorods, nanotubes, and nanodisks, among all zinc oxide nanostructures, have more adsorption sites and a more significant surface area than nanoparticles and nanolayers.…”
