Cytochromen: de ‘draadjes’ van microbiële elektronentransport – betekenis voor MIC
Cytochromen: de ‘draadjes’ van microbiële elektronentransport – betekenis voor MIC Cytochromen: de ‘draadjes’ van microbiële elektronentransport – betekenis voor MIC Cytochromen zijn heemdragende eiwitten die elektronen transporteren. In veel bacteriën vormen met name c-type multi-heem cytochromen ketens van heemgroepen die elektronen geleiden tussen celinterieur en vaste substraten (mineralen, metalen, elektrodes). Dit artikel plaatst die biochemie […]
Cytochromes as microbial electron ‘wires’ — and how on-site qPCR turns this into decisions
Cytochromes as microbial electron ‘wires’ — and how on-site qPCR turns this into decisions Cytochromes as microbial electron ‘wires’ — and how on-site qPCR turns this into decisions Cytochromes are heme proteins that carry electrons. In many bacteria, multi-heme c-type cytochromes form chains that conduct electrons across the cell envelope to solids (minerals, metals, electrodes). […]
Extracellular RNA ‘wiring’ enables direct electron uptake – implications for MIC
Extracellular RNA ‘wiring’ enables direct electron uptake – implications for MIC Extracellular RNA ‘wiring’ enables direct electron uptake – implications for MIC Short extracellular RNAs (eRNA) at the surface of Methanosarcina barkeri fold into G-quadruplex (G4) structures that form a conductive lattice for extracellular electron transfer (EET). This offers a cytochrome-independent route for electromethanogenesis and […]
MPN testing for MIC: Does culture-based enumeration still fits in modern corrosion monitoring?
MPN testing for MIC: Does culture-based enumeration still fits in modern corrosion monitoring? The Most Probable Number (MPN) method has been a cornerstone of oilfield microbiology for decades. In MIC (Microbiologically Influenced Corrosion) programs, MPN remains valuable for routine field surveillance of functional groups such as SRB, NRB, and APB—when used with appropriate controls and […]
>Van mechanisme naar praktijk: micH & micC biomarkers maken MIC-detectie in het veld kwantitatief
Van mechanisme naar praktijk: micH & micC biomarkers maken MIC-detectie in het veld kwantitatief Microbiologically Influenced Corrosion (MIC) ontstaat door overlappende elektrochemisch-microbiologische routes. Met micH (corrosieve methanogenen) en micC (corrosieve SRB) zijn er nu mechanistische biomarkers die via qPCR in pig-debris en produced water gericht én kwantitatief kunnen worden gedetecteerd. Samenvatting Probleem: Hoge 16S-rRNA aantallen […]
From mechanisms to field practice: micH & micC biomarkers bring quantitative MIC detection to the site
From mechanisms to field practice: micH & micC biomarkers bring quantitative MIC detection to the site Microbiologically Influenced Corrosion (MIC) is driven by overlapping electrochemical–microbiological pathways. Mechanistic biomarkers—micH (corrosive methanogens) and micC (corrosive SRB)—now enable targeted, quantitative detection in pig debris and produced water, moving field decisions from assumptions to evidence. Executive summary Why this […]
MIC explained: what the latest scientific review means for asset owners
MIC explained: what the latest scientific review means for asset owners Microbiologically Influenced Corrosion (MIC) encompasses several electrochemical and microbiological processes that accelerate or alter metal degradation. A recent scientific review highlights how understanding these interactions requires an integrated view of microbiology, electrochemistry, metallurgy, and operational factors. This article summarizes key mechanisms and practical implications […]
MIC uitgelegd: wat het nieuwste overzichtsartikel betekent voor asset owners
MIC uitgelegd: wat het nieuwste wetenschappelijke overzichtsartikel betekent voor asset owners Microbiologically Influenced Corrosion (MIC) omvat meerdere elektrochemische en microbiologische processen die de aantasting van metalen kunnen versnellen of wijzigen. Een recent overzichtsartikel laat zien dat inzicht in MIC alleen mogelijk is wanneer microbiologie, elektrochemie, metallurgie en operationele factoren gezamenlijk worden beschouwd. In deze blog […]
Comparative Assessment of qPCR, ATP, and Bactiquant Technologies for Microbial Growth Monitoring in Oilfield Waters
Microbial growth in oilfield waters contributes to biofouling and microbiologically influenced corrosion (MIC), necessitating effective monitoring techniques. This study provides a comparative assessment of three microbial detection methods—quantitative polymerase chain reaction (qPCR), adenosine triphosphate (ATP) assay, and Bactiquant—each employed to monitor microbial growth and activity in oilfield water systems. We explore their respective capabilities, limitations, […]
