This book was released on 2014 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation describes the effects of microbial attachment and biofilm formation on microbiologically influenced corrosion (MIC). The participation of microbes in the corrosion process includes initial attachment, biofilm formation, localized environment changing, and eventually, corrosion. Initial microbial attachment is considered as the first step of MIC. In the first part of this study, the initial attachment of three bacteria, Pseudomonas aeruginosa, Escherichia coli, and Pseudomonas putida, on two substrates, glass and octadecyltrichlorosilane (OTS) modified glass, was examined in flow chambers. The attachment trend on glass could be explained by the secondary minima and energy barriers as predicted by the extended Derjaguin-Landau-Verwey-Overbeek (XDLVO) theory. This part of study generated some insights into the effects of cell and substrate surface properties on initial bacterial attachment. In addition to the surface and medium properties, other factors such as the shear associated flow conditions could be one of the most important factors affecting initial bacterial attachment as well. In the second part of this study, four bacteria, Staphylococcus epidermidis, P. aeruginosa, P. putida, and E. coli, were examined for their attachment to glass and OTS modified glass under different shears. The results from this part of the study suggested that, without complications from surface features/extracellular polymeric substances (EPS), the analysis based on the XDLVO theory could provide a basis for understanding shear effect on initial bacterial attachment. The critical shear stress, a measure of bacterial attachment strength, was found to be correlated with the maximum attractive force towards the secondary energy minimum. As microbes attach and develop into biofilm on metal surfaces, the localized environment of metal surfaces could be changed by the influence of microbial metabolism. The third part of this study is intended to evaluate how early stage of biofilm formation affects carbon steel and aluminum alloy corrosion. In this part, aluminum alloy (Al 3003 H14) coupons and carbon steel (CS C1010) coupons were used, along with two common bacterial strains, P. aeruginosa and E. coli. Results showed that bacterial attachment strength and subsequent biofilm development could strongly influence metal corrosion behaviors. In the fourth part of this study, corrosion behaviors of carbon steel (CS C1010) and stainless steel (SS 304) in the presence of iron-oxidizing bacteria: Acidithiobacillus ferrooxidans was examined. Results showed that, due to the extremely high oxidizing rate of Fe(II) to Fe(III), A. ferrooxidans cells can accelerate CS corrosion, while SS 304 showed a good resistance to corrosion. The accelerated CS corrosion was likely related to the metabolism of A. ferroxidans, but not to the attachment strength and biofilm development of A. ferroxidans. In the last part, corrosion behaviors of aluminum alloy (Al 2024) in the presence of Trichoderma reesei and Aspergillus niger were evaluated. Results showed that T. reesei or A. niger could not firmly attach to Al coupon surfaces in an aqueous environment, and they could not corrode Al 2024 under our experimental conditions.

Download or read book Microbiologically Influenced Corrosion in the Upstream Oil and Gas Industry written by Torben Lund Skovhus and published by CRC Press. This book was released on 2017-03-03 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microorganisms are ubiquitously present in petroleum reservoirs and the facilities that produce them. Pipelines, vessels, and other equipment used in upstream oil and gas operations provide a vast and predominantly anoxic environment for microorganisms to thrive. The biggest technical challenge resulting from microbial activity in these engineered environments is the impact on materials integrity. Oilfield microorganisms can affect materials integrity profoundly through a multitude of elusive (bio)chemical mechanisms, collectively referred to as microbiologically influenced corrosion (MIC). MIC is estimated to account for 20 to 30% of all corrosion-related costs in the oil and gas industry. This book is intended as a comprehensive reference for integrity engineers, production chemists, oilfield microbiologists, and scientists working in the field of petroleum microbiology or corrosion. Exhaustively researched by leaders from both industry and academia, this book discusses the latest technological and scientific advances as well as relevant case studies to convey to readers an understanding of MIC and its effective management.

Download or read book Microbially Induced Corrosion and its Mitigation written by Ajay K. Singh and published by Springer Nature. This book was released on 2020-09-24 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: This brief covers case studies on Microbial Induced Corrosion (MIC) and its mitigation. After reviewing the basics of corrosion, it focuses on MIC. MIC is a special type of electrochemical corrosion in which the presence of microbes and bacteria alters the chemistry of liquid media so as to make them more corrosive. These changes are harmful to metallic equipment, processing machinery, marine vessels, etc. in an environment that is host to a wealth of microorganisms. A 2007 US survey estimated corrosion-related damages to cost $276 billion a year, roughly 50% of which are due to MIC. The industries most affected by MIC are power production, oil exploration, transportation and storage, water distribution and more generally all industries involving marine environments. However, means for effectively preventing and controlling MIC are poorly understood. As such, the book’s later chapters address various mechanisms/processes that show promise with regard to MIC mitigation. Lastly, the book discusses the strategies currently being explored to mitigate MIC using green technologies.

Download or read book Biofouling and Biocorrosion in Industrial Water Systems written by Hans-Curt Flemming and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microbial growth and contamination ("Biofouling") in water systems represents a significant threat to the quality of waters produced for the microelectronic, pharmaceutical, petroleum, paper, food and other manufacturing industries. Biofouling can lead to biologically induced corrosion ("Biocorrosion"), which can cause severe damage to the equipment. Both biofouling and biocorrosion are frequently not recognized in time, underestimated, or linked with the wrong causes. The book represents a new approach by introducing biofilm properties and dynamics as basic principles of biofouling and biocorrosion, thus providing a better understanding and the means of fighting the undesired effects of biofilms. The most important features are: Case histories of biofouling in water treatment.- Detection and monitoring of biofouling.- Reverse osmosis membrane biofouling.- Biocide efficacy and biofouling control.- Plant design considerations for preventing biofouling.- Case histories of biocorrosion.- Detection, monitoring, control and prevention of biocorrosion.- Fundamentals of biofouling and biocorrosion mechanisms.

Download or read book Biofilms written by L V Evans and published by CRC Press. This book was released on 2003-09-02 with total page 507 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biofilms affect the lives of all of us, growing as they do for example on our teeth (as plaque), on catheters and medical implants in our bodies, on our boats and ships, in food processing environments, and in drinking and industrial water treatment systems. They are highly complex biological communities whose detailed structure and functioning is only gradually being unravelled, with the development of increasingly sophisticated technology for their study. Biofilms almost always have a negative impact on human affairs (flocs in sewage treatment plants are a major exception) and a lot of research is being carried out to gain a better understanding of them, so that we will be in a better position to control them. This volume, with contributions by international experts from widely diverse areas of this field, presents a state-of-the-art picture of where we are at present in terms of our knowledge of biofilms, the techniques being used to study them, and possible strategies for controlling their growth more successfully. It should provide a valuable reference source for information on biofilms and their control for many years to come.

This book was released on 2013-06-29 with total page 666 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume, unlike the three preceding it, represents the collected papers from an experiment with an "electronic symposium". Co-participators in this symposium included The George Washington University, The Smithsonian Institution, Clark Atlanta University, the Agriculture Research Service of the United States Department of Agriculture, The University of Georgia, Morris Brown College, Spellman College, Morehouse College, North Carolina State University at Raleigh, The United States Food and Drug Administration, and the Forest Service of the United States Department of Agriculture among others. This unusual "electronic symposium" concept was developed by members of the Program, Planning and Organizing Committee as an alternative to the more costly convention-type symposium. As before, leading scientists in specific topic areas were invited to participate. Topic Session chairpersons were encouraged to arrange their own method of communication by telephone, electronic mail, or conference call, and report their findings back to the symposium center at The George Washington University. Additional papers were accepted from individuals and laboratories who are actively involved in relevant areas of research and study. Participation was also arranged for internationally established scientists. International authors are represented herein from Nigeria, Italy, Spain, Brazil and Argentina. Our goal was to present a research composite volume that reflected current developments, informed reviews, new and recently developing areas of the present state of knowledge as it relates to these proceeding topics. All of the reports included in this volume have undergone scientific, technical and editorial peer review.

Download or read book Effect of Quarum Sensing on the Biofilm Formation and Microbially Induced Corrosion for Sulfate Reducing Bacteria written by Vaibhav Handa and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Bacterial Biofilms written by Tony Romeo and published by Springer Science & Business Media. This book was released on 2008-02-26 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout the biological world, bacteria thrive predominantly in surface-attached, matrix-enclosed, multicellular communities or biofilms, as opposed to isolated planktonic cells. This choice of lifestyle is not trivial, as it involves major shifts in the use of genetic information and cellular energy, and has profound consequences for bacterial physiology and survival. Growth within a biofilm can thwart immune function and antibiotic therapy and thereby complicate the treatment of infectious diseases, especially chronic and foreign device-associated infections. Modern studies of many important biofilms have advanced well beyond the descriptive stage, and have begun to provide molecular details of the structural, biochemical, and genetic processes that drive biofilm formation and its dispersion. There is much diversity in the details of biofilm development among various species, but there are also commonalities. In most species, environmental and nutritional conditions greatly influence biofilm development. Similar kinds of adhesive molecules often promote biofilm formation in diverse species. Signaling and regulatory processes that drive biofilm development are often conserved, especially among related bacteria. Knowledge of such processes holds great promise for efforts to control biofilm growth and combat biofilm-associated infections. This volume focuses on the biology of biofilms that affect human disease, although it is by no means comprehensive. It opens with chapters that provide the reader with current perspectives on biofilm development, physiology, environmental, and regulatory effects, the role of quorum sensing, and resistance/phenotypic persistence to antimicrobial agents during biofilm growth.
