MIC explained: what the latest scientific review means for asset owners
MIC Explained: What Asset Owners Need to Know | MICBUSTERS MIC fundamentals MIC Is More Than Microorganisms: What Asset Owners Should Know Microbiologically influenced corrosion is not one organism, one mechanism or one recognisable pit shape. A defensible assessment connects microorganisms and their functions with the local chemistry, material, damage, sample location and operating history. […]
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 […]
Sulfate-Reducing Bacteria (SRB) Associated with Corrosion
Here is a list of key sulfate-reducing bacteria (SRB) and sulfate-reducing archaea (SRA) that are associated with corrosion, particularly in environments such as pipelines, marine structures, and wastewater systems. These microorganisms contribute to corrosion through the production of hydrogen sulfide (H₂S), which reacts with metals to form metal sulfides, leading to material degradation. Sulfate-Reducing Bacteria […]
Sulfur-Oxidizing Bacteria Associated with Corrosion
Thiobacillus spp. Thiobacillus thiooxidans: Acidophilic, chemolithoautotrophic, and efficient in oxidizing elemental sulfur and sulfide to sulfuric acid, especially in acidic environments. Thiobacillus ferrooxidans (now reclassified as Acidithiobacillus ferrooxidans): Known for its role in sulfur and iron oxidation; common in mining environments where it drives bioleaching and accelerates corrosion. Acidithiobacillus spp. Acidithiobacillus thiooxidans: Capable of oxidizing […]
The Role of Sulfur-Oxidizing Bacteria in Corrosion Processes and the Application of qPCR for Characterization
Sulfur-oxidizing bacteria (SOB) are key contributors to microbiologically influenced corrosion (MIC), particularly in acidic environments such as those associated with acid mine drainage (AMD) and black shale deposits. SOB accelerate corrosion through their metabolic conversion of sulfur compounds into sulfuric acid, leading to severe degradation of both metal and concrete structures. This article reviews the […]
Intertidal Corrosion on Sheet Piles and the Role of Microbiological Measurement via qPCR
Steel corrosion in intertidal zones represents a significant challenge in marine engineering. This phenomenon, often exacerbated by microbially influenced corrosion (MIC), involves complex biochemical reactions that rapidly degrade structural integrity in marine environments. Measuring microbial activity, particularly through quantitative polymerase chain reaction (qPCR), provides insight into the extent and mechanisms of microbial involvement in corrosion. […]
