Microbiologically Influenced Corrosion (MIC) is a growing problem in the oil and gas industry resulting in huge financial losses. Sulfate Reducing Bacteria (SRB) are often the culprits although many other microorganisms can also be directly or indirectly involved. From the bioprocess engineering angle, mass transfer and flow conditions are very important in SRB biofilm formation and MIC corrosi...

Acid rain sulphate (SO4 2 ) deposition is a known suppressant of methane (CH4) emission from wetlands. However, the hypothesised mechanism responsible for this important biogeochemical interaction, competitive exclusion of methanogens by dissimilatory SO4 2 reducing bacteria (SRB), lacks supporting evidence. Here, we present data from an acid rain simulation experiment in the Moidach More peat ...

All toxic metals have been known to inhibit different activities of sulphate-reducing bacteria (SRB) at different concentrations. The present study delineates functional responses of two thermophilic SRB species (Desulfotomaculum reducens-HA1 and Desulfotomaculum hydrothermale-HA2) to toxic metals. Bacterial activity was assessed in terms of sulphate reduction and metal precipitation employing ...

Sulfate-reducing bacteria (SRB) are one of the main protagonist groups of biocorrosion in the seawater environment. Given their principal role in biocorrosion, it remains a crucial task to develop strategies to reduce the abundance of SRBs. Conventional approaches include the use of biocides and antibiotics, which can impose health, safety, and environmental concerns. This review examines an al...

The conversion of sulfate to an excess of free sulfide requires stringent reductive conditions. Dissimilatory sulfate reduction is used in nature by sulfate-reducing bacteria for respiration and results in the conversion of sulfate to sulfide. However, this dissimilatory sulfate reduction pathway is inhibited by oxygen and is thus limited to anaerobic environments. As an alternative, we have me...

Screen printed electrode (SPE) is considering one of the most prospective techniques for sensing purposes due to its low cost, easy fabrication and reusability. It worthwhile use SPE as a sensor fast detection biogenic H2S gas which sign sulfate-reducing bacteria (SRB) existence. SRB presence first indicator in industrial sector that causes catastrophic environmental issue give time decision ma...

Dissimilatory sulfate-reducing prokaryotes (SRB) are a very diverse group of anaerobic bacteria that are omnipresent in nature and play an imperative role in the global cycling of carbon and sulfur. In anoxic marine sediments sulfate reduction accounts for up to 50% of the entire organic mineralization in coastal and shelf ecosystems where sulfate diffuses several meters deep into the sediment....

Currently, a lot of researcher’s attention is devoted to the problem microbiologically influenced corrosion (MIC), since it causes huge damages economy, initiating destruction oil and gas pipelines other underground constructions. To protect industrial materials from MIC effects an organic chemical inhibitors are massively used. However, their use associated with toxicity, dangerous for environ...

Abstract The main goal of this study was to develop a cost-efficient biological method for the removal sulfate from mining effluents in cold conditions. A consortium cold-tolerant sulfate-reducing bacteria (SRB) tested at 6 °C regarding utilization economically viable, low-cost carbon sources, i.e., whey, conditioned sewage sludge, and peat, synthetic water. Succinate used as reference source. ...
