“…The maximum diameter of the pit photographed was 22.74 µm. These suggest that SRB causes local corrosion rather than general corrosion, which is consistent with the results reported by Fan et al (2021).…”

“…SRB is a group of facultative anaerobic heterotrophic bacteria widely distributed in the natural environment, which can reduce SO 4 2− as a receptor to S The corrosion induced by SRB includes the direct or indirect actions between SRB and steel (Dake et al, 2013). SRB can obtain electrons from elemental iron (Fe 0 ) to reduce sulfate leading to the acceleration of steel corrosion, especially for localized corrosion (Dec et al, 2016;Fan et al, 2021). Now several mechanisms have been proposed for the corrosion of metals by SRB.…”

Microbiologically influenced corrosion (MIC) is one of the reasons leading to the service failure of pipelines buried in the soil. To investigate the effect of sulfate-reducing bacteria (SRB) on the corrosion behavior of Q235 carbon steel in groundwater, a hanging plate test was carried out and the SRB was characterized by electrochemical methods, surface analysis, and biological analysis. In addition, a group of blank experiments was used as a control. The results showed that SRB continued to grow and reproduce in groundwater without lacking a carbon source for 14d to maintain life activities. The community structure has changed after corrosion, and the dominant species of SRB has changed from Desulfovibrio to Desulfosporosinus. During the whole growth cycle, the electrochemical results demonstrated that the impedance of the carbon steel surface forming a biofilm was 1 order of magnitude higher than that of other periods, and the formed ferrous sulfide layer also hindered the occurrence of corrosion. In comparison to the condition without SRB, the inclusion of SRB results in reduced weight loss. The average weight loss with SRB is 0.01389 g, whereas the average weight loss without SRB is 0.03956 g. However, the 3D topography indicated that the surface of carbon steel was more uneven and pits were increased with SRB. Altogether these results implied that the growth of SRB makes the corrosion process of Q235 carbon steel more complicated.

“…The soil environment that the pipeline steel served in is usually anaerobic or hypoxic, which provides necessary conditions for the survival of anaerobic sulfatereducing bacteria (SRB) 11,12 . Therefore, SRB corrosion has become the main MIC type of pipeline steel, and has received extensive attention from scholars and engineers throughout the world [13][14][15] .…”

Sulfate-reducing bacteria (SRB) corrosion of X80 steel welded joint under organic carbon source starvation was investigated in the paper. The results showed that the number of planktonic cells is much less than that of sessile cells after 720 h immersion. The number of sessile cells in the base metal (BM) in the medium with 1% carbon source is the largest. Starving SRB cells accelerated simultaneously the uniform corrosion and localized corrosion of the welded joints, and the acceleration effect on the latter was much higher than that of the former. In all mediums, the density and average depth of pits in the BM and weld zone (WZ) were much larger than those in the heat affected zone (HAZ). SRB corrosion of the welded joint was strongly selective, and organic carbon source starvation further enhanced the selectivity.

“…With the ongoing gigantic research trends in bacterial detection, the ultrasensitive determination of sulfate-reducing bacteria (SRB) has become one of the rapidly growing research themes owing to their crucial roles in environmental and industrial harms together with the early detection of microbial corrosion. , A plethora of microbes are causing microbiologically induced corrosion (MIC), while SRB are the main culprits that induce half of all occurrences of MIC damaging approximately 75% of oil reservoirs and causing 50% of failures of oil pipelines . 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 .…”

The ultrasensitive determination of sulfate reducing bacteria (SRB) is of great significance for their crucial roles in environmental and industrial harms together with the early detection of microbial corrosion. In this work, we report the development of highly efficient electrocatalysts, i.e., Cu 2 O-CuO extended hexapods (EHPs), which are wrapped on homemade freestanding graphene paper to construct a flexible paper electrode in the electrochemical sensing of the biomarker sulfide for SRB detection. Herein Cu 2 O-CuO EHPs have been synthesized via a highly controllable and facile approach at room temperature, where the redox centers of copper oxide nanoarchitectures are tuned via facet engineering, and then they are deposited on the graphene paper surface through an electrostatic adsorption to enable homogeneous and highly dense distribution. Owing to the synergistic contribution of high electrocatalytic activity from the Cu mixed oxidation states and abundant catalytically active facets of Cu 2 O-CuO EHPs and high electrical conductivity of the graphene paper electrode substrate, the resultant nanohybrid paper electrode has exhibited superb electrochemical sensing properties for H 2 S with a wide linear range up to 352 μM and an extremely low detection limit (LOD) of 0.1 nM with a signal-to-noise ratio of 3 (S/N = 3), as well as high sensitivity, stability, and selectivity. Furthermore, taking advantage of the good biocompatibility and mechanical flexibility, the electrochemical sensing platform based on the proposed electrode has been applied in the sensitive detection of SRB in environmental samples through the sensing of sulfide from SRB, which holds great promise for on-site and online corrosion and environmental monitoring.
