Microbially Influenced Corrosion of Industrial Materials
This communication outlines the principles of application of scanning probe microscopy (SPM) as a tool for studying physico-chemical and biological phenomena and discusses the potential use of atomic force microscopy (AFM), a form of SPM, for investigation of bacterial biofilms formed on metal surfaces and for studying corrosion of these surfaces in the presence of such biofilms. AFM images sho...
متن کاملThe role of acetogens in microbially influenced corrosion of steel
Microbially influenced corrosion (MIC) of iron (Fe(0)) by sulfate-reducing bacteria (SRB) has been studied extensively. Through a mechanism, that is still poorly understood, electrons or hydrogen (H2) molecules are removed from the metal surface and used as electron donor for sulfate reduction. The resulting ferrous ions precipitate in part with the sulfide produced, forming characteristic blac...
متن کاملMicrobially influenced corrosion as a model system for the study of metal microbe interactions: a unifying electron transfer hypothesis.
The general term biomineralisation refers to biologically induced mineralisation in which an organism modifies its local microenvironment creating conditions such that there is chemical precipitation of mineral phases extracellularly. Most usually this results from an oxidation or reduction carried out by some microbial species, with the formation of a recognised biomineralised product. These r...
متن کاملCharacterization of Bulk Water Samples from Copper Pipes Undergoing Microbially Influenced Corrosion by Diagnostic Metabolomic Profiling
This paper presents the application of metabolomic techniques to determine the presence of microbial influenced corrosion (MIC). In a previous study, the extracellular metabolites expressed from pipe biofilm was identified by analysing the passing water. This investigation extends this work by successfully applying a chemometric statistical analysis to the extracellular metabolomic profile of a...
متن کاملUse of Homogeneously-Sized Carbon Steel Ball Bearings to Study Microbially-Influenced Corrosion in Oil Field Samples
Microbially-influenced corrosion (MIC) contributes to the general corrosion rate (CR), which is typically measured with carbon steel coupons. Here we explore the use of carbon steel ball bearings, referred to as beads (55.0 ± 0.3 mg; Ø = 0.238 cm), for determining CRs. CRs for samples from an oil field in Oceania incubated with beads were determined by the weight loss method, using acid treatme...
