Book excerpt: Methyl tertiary butyl ether (MTBE), a widely used gasoline oxygenate, has been added to gasoline over the past 25 years to increase the octane rating and reduce air pollution from vehicle emissions. tertiary butyl alcohol (TBA) has also been used as a gasoline oxygenate and is a key intermediate in the biodegradation of MTBE. The frequent detection of these compounds as ground water contaminants has raised public health concerns and addresses the need for their remediation. This research focuses on the characterization of the physiology and enzymology of microorganisms able to grow on MTBE and TBA. In this study, we isolated and characterized two aerobic bacterial strains able to utilize TBA as a sole source of carbon and energy. Strains, Hydrogenophaga G2B2 and Aquincola S1B1 rapidly oxidized TBA, but were unable to grow on MTBE or oxidize MTBE after growth on TBA. Using a novel approach combining a fluorinated analog of TBA, 2-trifluoromethyl-2-propanol (TFMP), with 19F-nuclear magnetic resonance (19F-NMR) spectroscopy, we also report the detection of the initial TBA biodegradation pathway intermediates 2-methyl-1,2-propanediol (2M12PD) and 2-hydroxyisobutyric acid (2HIBA) with both strains S1B1 and G2B2. We also demonstrated the cometabolic oxidation of MTBE by a defined co-culture containing Pseudomonas mendocina KR1 and our isolate Aquincola S1B1. MTBE degradation was achieved through the n-alkane dependent cometabolic oxidation of MTBE by strain KR1 with the subsequent assimilation of TBA by strain S1B1. We also report the identification of polypeptides induced after the growth of strain S1B1 on TBA. Our initial results suggest that these proteins are enzymes associated with TBA oxidation in this strain. Our final study examined the biodegradation of MTBE by the MTBE-metabolizing strain Methylibium petroleiphilum PM1. Our results demonstrated that the MTBE biodegradation pathway of strain PM1 includes the intermediates TBA, 2M12PD, and 2HIBA. Furthermore, our.

Book Synopsis Compound-specific Stable Isotope Analysis by : Maik A Jochmann
Download or read book Compound-specific Stable Isotope Analysis written by Maik A Jochmann and published by Royal Society of Chemistry. This book was released on 2015-11-09 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of Compound-specific Stable Isotope Analysis (CSIA) is increasing in many areas of science and technology for source allocation, authentication, and characterization of transformation reactions. Until now, there have been no textbooks available for students with an analytical chemical background or basic introductory books emphasising the instrumentation and theory. This book is the first to focus solely on stable isotope analysis of individual compounds in sometimes complex mixtures. It acts as both a lecture companion for students and a consultant for advanced scientists in fields including forensic and environmental science. The book starts with a brief history of the field before going on to explain stable isotopes from scratch. The different ways to express isotope abundances are introduced together with isotope effects and isotopic fractionation. A detailed account of the required technical equipment and general procedures for CSIA is provided. This includes sections on derivatization and the use of microextraction techniques in GC-IRMS. The very important topic of referencing and calibration in CSIA is clearly described. This differs from approaches used in quantitative analysis and is often difficult for the newcomer to comprehend. Examples of successful applications of CSIA in food authenticity, forensics, archaeology, doping control, environmental science, and extraterrestrial materials are included. Applications in isotope data treatment and presentation are also discussed and emphasis is placed on the general conclusions that can be drawn from the uses of CSIA. Further instrumental developments in the field are highlighted and selected experiments are introduced that may act as a basis for a short practical course at graduate level.

Book Synopsis The Biological Fractionation of Isotopes by : Eric Galimov
Download or read book The Biological Fractionation of Isotopes written by Eric Galimov and published by Elsevier. This book was released on 2012-12-02 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Biological Fractionation of Isotopes focuses on the biological fractionation of isotopes and presents calculations of the thermodynamic isotopic beta factor for polyatomic carbon compounds. This book provides experimental and theoretical evidence of the phenomenon of thermodynamically ordered distribution of isotopes in biological systems. This book consists of 12 chapters and opens with an overview of the causes of fractionation of isotopes, along with concepts such as isotopic composition and isotopic effects. The discussion then turns to the isotopic composition of the carbon of organisms; a method of calculating the thermodynamic isotopic factors of polyatomic compounds; and results of experimental investigations of intermolecular and intramolecular isotopic effects. A theoretical model of biological fractionation of isotopes is also described. The following chapters explore the regularities of the biological distribution of isotopes and present the results of some biochemical experiments, including the enzymatic decarboxylation of pyruvate and microbiological oxidation of ethanol to acetic acid. In addition, the geologic aspects of thermodynamically ordered isotopic distributions in biological products are analyzed. This monograph will be of interest to biologists, geochemists, analytical chemists, and geologists.

Book Synopsis Organic Chemicals in the Environment by : Alasdair H. Neilson
Download or read book Organic Chemicals in the Environment written by Alasdair H. Neilson and published by CRC Press. This book was released on 2012-09-05 with total page 1051 pages. Available in PDF, EPUB and Kindle. Book excerpt: Addressing the persistent environmental threat of organic chemicals with a fresh approach to degradation and transformation processes, Organic Chemicals in the Environment: Mechanisms of Degradation and Transformation, Second Edition examines a wide range of compounds as well as abiotic and microbiological reactions mediated by microorganisms. The book emphasizes the pathways used and the broad classes of enzymes involved. It provides an overview of experimental procedures with detailed coverage of the organic compounds that are considered to be xenobiotics. The book begins by providing a broad perspective on abiotic and biotic reactions, including the significance of a range of environmental determinants. The following chapters briefly introduce experimental procedures and emphasize those procedures for establishing the structure of metabolites using isotopes and physical methods. Next, the authors outline details of biochemical reactions involved in the biodegradation of the major groups of aliphatic, carbocyclic aromatic, and heterocyclic compounds. They end with coverage of bioremediation that has attracted increasing concern because of the hazard presented by the disposal of unwanted chemicals or by-products from their manufacture. Broad and comprehensive, this book provides a cohesive treatment of the subject. It contains an extensive set of literature references and numerous illustrative figures. The authors use a mechanistic approach with emphasis on the pathways, and the principles that emerge provide a guide not only for specific compounds but also for those having a more remote structural resemblance.
Book Synopsis Alternatives for Managing the Nation's Complex Contaminated Groundwater Sites by : National Research Council
Download or read book Alternatives for Managing the Nation's Complex Contaminated Groundwater Sites written by National Research Council and published by National Academies Press. This book was released on 2013-02-27 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: Across the United States, thousands of hazardous waste sites are contaminated with chemicals that prevent the underlying groundwater from meeting drinking water standards. These include Superfund sites and other facilities that handle and dispose of hazardous waste, active and inactive dry cleaners, and leaking underground storage tanks; many are at federal facilities such as military installations. While many sites have been closed over the past 30 years through cleanup programs run by the U.S. Department of Defense, the U.S. EPA, and other state and federal agencies, the remaining caseload is much more difficult to address because the nature of the contamination and subsurface conditions make it difficult to achieve drinking water standards in the affected groundwater. Alternatives for Managing the Nation's Complex Contaminated Groundwater Sites estimates that at least 126,000 sites across the U.S. still have contaminated groundwater, and their closure is expected to cost at least $110 billion to $127 billion. About 10 percent of these sites are considered "complex," meaning restoration is unlikely to be achieved in the next 50 to 100 years due to technological limitations. At sites where contaminant concentrations have plateaued at levels above cleanup goals despite active efforts, the report recommends evaluating whether the sites should transition to long-term management, where risks would be monitored and harmful exposures prevented, but at reduced costs.
