... reported as related to MIC. On the other hand, the biofilm formation was characterized by SEM-EDS and electrochemical techniques, using its ability of MIC in carbon steel; showing that the unconventional microbial consortium slightly higher corrosion capacity (2.35 mm/y) than the conventional microbial...

...-8700 Horsens, Denmark ABSTRACT Studies in microbiologically influenced corrosion (MIC) have reported on the effects of pre- corrosion surface deposits on the localized pitting which occurs on metals. But due to the complexity and heterogeneity of these deposits, which include biofilms, it is necessary...

Guezennec et al 1994 studied the relationship between bacterial colonization and cathodic current density, but only using single culture or co-cultures of microorganisms. A negative influence of microbial biofilm...

... microbiologically influenced corrosion (MIC) in pipelines is challenging to mitigate, it is generally accepted that pigging, a mechanical cleaning process that removes water, scales and other solids from the pipeline surface, is an effective method to control biofilm formation. However, not all pipelines can...

For passive materials such as Cr Ni Mo stainless steels and nickel-based alloys, the specificity of the above parameters in deep sea environment might have an impact on both initiation and propagation phases...

... of problems such as MIC, biofilm formation, and reservoir souring. 1,2,3 The most commonly used biocides in the oil and gas industry can be classified as either oxidizing or non-oxidizing. Oxidizing biocides include active chemistries like peracetic acid, ozone, chlorine dioxide, and hypochlorite. Common non...

... ABSTRACT Within the last decade researchers have gained a significant understanding of the role of biofilms in the onset of microbial-influenced corrosion in anthropogenic water systems. Biofilms are the preferred habitat for microorganisms and in this environment they are protected from...

It is typically characterized by the presence of microbiological populations within a biofilm or semi-solid deposit resulting in localized and accelerated corrosion. While MIC has been actively studied for decades, there is still...

Type II MIC, also known as metabolite MIC (M-MIC), is caused by secreted corrosive metabolites that are more concentrated locally under a biofilm. The corrosive...
