“…Liu proposed the reduction of COD and nutrient limitation as strategies for controlling biological pollution without the need for increased bactericide usage [20]. In a different approach, bio-competitive exclusion (BE) strategies have been employed to curb the growth of sulfate-reducing bacteria (SRB) and MIC in the oil industry [21]. This study verified that there was a synergistic inhibition of SRB by adding nitrate-reducing bacteria (NRB), nitrate, nitrite, and molybdate to the system.…”

The use of phosphorus-containing chemical corrosion and scale inhibitors has been found to result in excessive phosphorus discharge and an inability to reduce the high concentration of CODcr in the circulating cooling water, thereby making it challenging to comply with increasingly stringent sewage discharge standards. This study aims to assess the practicality of utilizing biological corrosion and scale inhibitors in coal power plants’ operation, as well as investigating the correlation between water quality indicators and microbial communities during the conversion period. The data illustrates that, in comparison to the chemical method, there is a decrease in turbidity of the circulating water from 19.44 NTU to 9.60 NTU, a reduction in CODcr from 71.55 mg/L to 45.47 mg/L, and a drop in TP from 2.35 mg/L to 0.38 mg/L. Microbial community analysis during the transition period reveals that microorganisms rapidly establish a new equilibrium in the circulating water, sediment, and fiber ball, resulting in significantly different microbial community structures. The relative abundance of corrosive microorganisms such as Flavobacterium, Pedomicrobium, and Hydrogenophaga is significantly diminished in the circulating water, whilst the abundance of anaerobic microorganisms like Anaerolineaceae and Rhodopseudomonas in the sediment also declines. Conversely, there is an increased presence of microorganisms associated with contaminant degradation, such as CL500-3 and SM1A02. These findings suggest a decrease in the risk of system corrosion and an enhancement in contaminant degradation capability. This study provides evidence supporting the replacement of chemical agents with biological agents in circulating cooling water systems, contributing to more environmentally friendly and sustainable practices.

“…Sulfate-(SRB) and nitrate-reducing bacteria (NRB) are well-known for their ability to accelerate MIC via EET. Much attention has been paid to the corrosion affected by their coexistence [11][12][13][14][15][16]. Fu et al evaluated the corrosion behavior of X80 steel in the presence of SRB, NRB, and mixed biofilms in a soil solution containing 48 mg•L −1 sulfate and 46 mg•L −1 nitrate.…”

The Nitrate-Dependent Impact of Carbon Source Starvation on EH40 Steel Corrosion Induced by the Coexistence of Desulfovibrio vulgaris and Pseudomonas aeruginosa

Carbon source starvation can promote steel corrosion in the presence of a pure culture through extracellular electron transfer (EET). However, the impact of carbon source starvation on corrosion induced by mixed strains is still unknown. This work investigated the impact of carbon source starvation on EH40 steel corrosion in the presence of Desulfovibrio vulgaris and Pseudomonas aeruginosa, typical species of sulfate- and nitrate-reducing bacteria. It was found that the impact of carbon source starvation on corrosion depended on nitrate addition. When nitrate (5 g∙L−1 NaNO3) was not added, the corrosion was promoted by carbon source starvation. However, the corrosion was initially promoted by carbon source starvation, but later inhibited with nitrate addition. The corrosion behaviors in different systems were closely related to different numbers of the strains in biofilms and their metabolic activities, and the mechanisms were revealed.

“…The drsAB gene which encodes the DrsAB, had widely detected a range of SRB community structures, containing more than 20 different genera, such as Desulforibrio, Desulfomonas, Desulfobulbus, Desulfobacter, Desulfococcus, Desulfosarcina, Desulfonema, Desulfotomaculum and a genus Archaeoglobus within Archaea (Guan et al 2013, Lu et al 2017. Sulfate reduction mediated by microbes is often coupled to other interactions, such as fundamental biogeochemical processes, oil biodeterioration and biocorrosion, food spoilage, bioremediation the heavy metals and biodegradation of organic matter (George et al 2008, Lai et al 2020, Sheoran et al 2010). Hence, the biotechnologies of SRBs could also be utilized in a variety of environmental treatments, such as microbial remediation of the heavy metals in wastewater or contaminated soils, dichlorination of organochlorines and repair of acid mine drainage (Hu et al 2020, Shan et al 2019, Zhang et al 2016).…”

Microbial sulfate reduction, a vital mechanism for microorganisms living in anaerobic, sulfate-rich environments, is an essential aspect of the sulfur biogeochemical cycle. However, there has been no detailed investigation of the diversity and distribution of SRBs and its effect in Shimen Realgar Mine, which is characterized as a hot research area rich in sulfate. To elucidate this issue, soils sample from Shimen Realgar Mine were collected. Further, a total of 55 new or new-type dissimilatory sulfite reductase genes and 5 new families of DrsAB proteins were successfully identified, which demonstrate the rich and unique diversity of the sulfate reducing microbes in this environment. We also isolate a novel DSRP strain, Desulfotomaculum sp. JL90 from the soils, which can efficiently respiratory reduces sulfate and arsenate. JL90 also can promote the generation of yellow precipitations in the presence of multiple electron acceptors (both contain sulfate and As(V) in the cultures). Moreover, microbial community compositions also indicated the biogenesis contribution of SRBs to the Shimen realgar mine. The results of this study provided a new insight into the diversity and distribution of SRBs and its ecological effect in Shimen Realgar Mine.
