Book Description
Significantly extended from the first edition, this book presents the basics of microbiologically influenced corrosion (MIC) in an accessible and concise manner. It explores strategies for recognizing, understanding, mitigating and preventing this type of corrosion, and investigates this topic from the point of view of an engineer. Chapters cover issues including stress corrosion cracking and microbial corrosion, the pros and cons of biocides, the involvement of magnetic bacteria in microbial corrosion, and cathodic protection based on recent research in microbial environments. The 2nd Edition provides new material examining the following topics: *The corrosion-related bacteria clostridia *Mathematical modelling of MIC, in particular fuzzy logic *A comparison of culture-independent methods with culture-dependent methods *Further practical strategies for dealing with MIC *Natural biocidesThis book has provided course material for the author’s microbial corrosion workshops around the world, and it presents an invaluable resource to corrosion and integrity professionals working in a wide range of industries including power generation, oil and gas, marine, and mining. It is also intended for students and academics of corrosion engineering, materials science, microbiology, chemical engineering and welding.

Book Description
The annual financial impact on the oil and gas industry amounts to tens of billions of dollars, attributable to treatment costs directly and indirectly linked to corrosion. Approximately 20% of these corrosion-related damages are attributed to microbial-induced corrosion. During microbial-induced corrosion, microbes typically promote conditions that produce acids, converting metal oxide layers to a less protective metal sulfide or localizing anode and cathodes on a material. Due to the different disciplines required to research microbial-induced corrosion, different vocabularies and research approaches occur. The lack of clarity resulting from this situation, in turn, causes many questions to go unanswered. Notably, electroactive bacteria are not commonly studied transiently, meaning their growth dynamics' relationship to electrochemical activity over time is poorly understood. The major drawback is that no dynamic live studies are performed, making the distinction between biofilm-influenced corrosion and abiotic corrosion hard to differentiate. The electrode-biofilms interface is either optically or electrochemically researched. The disconnection between biology and electrochemical activity leads to a series of unknown parameters that link them. Lack of understanding of real-time interactions at bio-interface leads to microbial-induced corrosion knowledge gap. Here, we utilize a specially designed biological microelectromechanical microfluidic device, two-working electrode Scanning Electrochemical Microscopy, and molecular imprinted polymer-based sensors to improve the understanding of transient bio-interface interactions. These devices and techniques were established to study three domains: biofilm probing, biofilm dynamics, and biofilm sensing during the initial stages of microbial-induced corrosion. By utilizing these tools, we were able to observe a direct real-time correlation between the morphological characteristics of biofilm and the escalation of corrosion rates in microbial-induced corrosion. Additionally, we also observed the spatial distribution of redox-active quasi-quorum sensing molecules and their direct correlation to the heightened corrosion rates. This research is a significant advancement in our understanding of the complex interplay between microbial activity and corrosion processes, and it provides crucial insights for devising effective corrosion mitigation strategies in a wide range of industrial settings.

Book Description
Sulfate reducing bacteria (SRB) have been reported to obliterate robust metals, including steel. They use a process known as microbiologically influenced corrosion (MIC) to damage civil infrastructure, including bridges and water pipelines. MIC accounts for up to ten percent of the total corrosion costs to the world economy. Quorum sensing (QS) is an inherent mechanism that allows microcosmic communications among the SRB cells. As a result, QS-mediated signaling induces genotypic and phenotypic changes regarding biofilm formation and MIC. The current study addresses the inducing effect of QS molecules (e.g., n-Acetyl homoserine lactone; AHL) on MIC resistance of conformal graphene (Gr) coatings used to protect underlying polycrystalline copper surfaces from corrosive effects of Oleidesulfovibrio alaskensis G20 (OA-G20). Graphene was chosen as a model for emerging protective coatings based on two dimensional (2D) materials. The external augmentation of AHL molecules greatly reduces the lag time required for OA-G20 cells to achieve peak corrosion rates. The transcriptomic analysis revealed that a total of 394 genes were differentially expressed in AHL supplemented condition compared to control, thus promoting the predominant metabolic regulation towards up-regulation pathways. The up-regulated and down-regulated genes were related to phenylalanine-tRNA ligase alpha subunit (4.4-folds - Dde_2635) and metallophos_3 domain-containing protein (4-folds – Dde_3615), respectively. The amino acid biosynthetic pathways and metal containing domain related proteins showed the maximal differential gene expression among all the genes. This fundamental knowledge can be used to design Gr-coatings that rationally consider the QS mechanisms in SRB.

Book Description
It has long been recognized that Sulphate Reducing Bacteria (SRB) found in natural and industrial waste waters promote Microbiologically Influenced Corrosion (MIC) of certain metals and alloys. X-ray Photoelectron Spectroscopy (XPS) is used in conjunction with conventional microbiological and quantitative chemical analytical techniques to better understand the effect of environmental conditions on microbial behavior as well as the ability of SRB to alter local environmental conditions (such as pH) in such a way as to accelerate corrosion. Specifically, the interactions of Fe, Cr, Ni and Mo ions with Desulfovibrio sp. under anoxic conditions were studied in order to determine the resulting speciation of the metal ions and sulfur.

Book Description
MIC, which is caused by the activities or metabolites of microorganisms, is a major threat to the oil and gas industry and many other industries. Corrosive microbial biofilms are the culprits behind MIC. Sulfate reducing bacteria (SRB) are one of the most investigated corrosive microorganisms because they are commonly present in anaerobic environments containing sulfate such as most oil and gas systems, and they are notoriously corrosive. However, the SRB MIC mechanisms are still not very clear. SRB and NRB (nitrate reducing bacteria) can use “energetic” metals such as Fe(0) as electron donors to replace organic carbon for respiration. Because metal oxidation occurs extracellularly while sulfate or nitrate reduction occurs intracellularly with biocatalysis, extracellular electron transfer (EET) is required. This kind of MIC is known as EET-MIC. MIC can also be caused by corrosive metabolites such as organic acids and H2S that are secreted by microbes, typically with much higher concentrations underneath biofilms than in the bulk fluid. This kind of MIC is known as metabolite MIC (M-MIC).
