Download or read book Genomes and Genomics of Nitrogen fixing Organisms written by Rafael Palacios and published by Springer Science & Business Media. This book was released on 2005-06-15 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genomes and Genomics of Nitrogen-fixing Organisms This is Volume 3 of a seven-volume series on all aspects of Nitrogen Fixation. The series aims to be the definitive authority in the field and to act as a benchmark for some years to come. Rather than attempting to cram the whole field into a single volume, the subject matter is divided among seven volumes to allow authors the luxury of writing in depth with a comprehensive reference base. All authors are recognized practicing scientists in the area of their contribution, which ensures the high quality, relevance, and readability of the chapters. In establishing the rationale for, and the organization of, this book, we realized the need to divide it into two sections. The first section should be organism based and should review our current knowledge of the genomes of nitrogen-fixing organisms and what these nucleotide sequences tell us. The second section should then be technology based. It should review what technologies are available to mine the data inherent in the nucleotide sequences and how they are now being used to produce gene-function data from differential gene expression.
Download or read book Dehalococcoides Ethenogenes Strain 195 written by Xavier Maymó-Gatell and published by . This book was released on 1997 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tetrachioroethene (PCE) is a human carcinogen, and together with trichloroethane (TCE), is widely used. Due to improper handling, they are among the most frequently found groundwater pollutants. A purified, PCE-dechlorinating enrichment culture was developed. This non-methanogenic, non-acetogenic culture could grow with H2 as the electron donor, indicating that H2/PCE serves as an electron donor/acceptor for energy conservation and growth. A novel anaerobic bacterium which dechlorinates PCE to the non-toxic product ethene (ETH), "Dehalococcoides ethenogenes' strain 195, was isolated from this enrichment. This is the first pure culture capable of complete PCE dechlorination. 'D. ethenogenes' strain 195 is an irregular coccus with an optimal growth temperature of 35 deg C and pH of 6.8-7.5. Phylogenetic analysis indicates that it is a eubacterium which shows no affiliation to known groups. Electron donors tested other than H2 were not utilized nor were electron donors other than TCE, cis-dichloroethene (cis-DCE), 1,1-DCE, and dichloroethane, which could be freely interchanged and were dechlorinated to ETH. This organism could not grow on vinyl chloride or trans-DCE when provided as sole electron acceptors, but both were dechlorinated cometabolically by cells previously grown on PCE. The reduction of VC to ETH was the rate-limiting reaction to the complete dechlorination of PCE. PCE, TCE, cis-DCE, and 1,1-DCE inhibited ETH formation from VC when present, but, at low concentrations, their dechlorination coexisted with ETH production. Cultures grown on cis-DCE as sole electron acceptor could not dechlorinate PCE unless PCE and cis-DCE were added together.

This book was released on 2012-12-06 with total page 723 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of bacterial genetics has been restricted for many years to Escherichia coli and a few other genera of aerobic or facultatively anaerobic bacteria such as Pseudomonas, Bacillus, and Salmonella. The prevailing view up to recent times has been that anaerobic bacteria are interesting organisms but nothing is known about their genetics. To most microbiologists, anaerobic bacteria appeared as a sort of distant domain, reserved for occasional intrusions by taxonomists and medical microbiologists. By the mid-1970s, knowledge of the genetics and molecular biology of anaerobes began to emerge, and then developed rapidly. but also im This was the result of advances in molecular biology techniques, portantly because of improvements in basic techniques for culturing anaerobes and for understanding their biochemistry and other areas of in terest. Investigations in this field were also stimulated by a renewal of interest in their ecology, their role in pathology and in biotransformations, and in the search for alternative renewable sources of energy. The initial idea for this book came from Thomas D. Brock. When Dr. Brock requested my opinion about two years ago on the feasibility of publishing a book on the genetics of anaerobic bacteria, as a part of the Brock/Springer Series in Contemporary Bioscience, I answered positively but I was apprehen sive about assuming the role of editor. However, I was soon reassured by the enthusiastic commitment of those I approached to contribute. Eventually, thanks to the caring cooperation of the contributors, the task became relatively easy.

Available in PDF, EPUB and Kindle. Book excerpt: Since the general recognition of the Archaebacteria, research into the evolution, metabolism, molecular biology and ecological roles of these fastidious anaerobes has proceeded at an ever-increasing pace. All possess a very novel biochemistry and many exploit unique ecological niches. Methanogens, which convert one-and-two carbon compounds into the important atmospheric gas methane, are the largest group among the Archaebacteria. Of all microbial groups, methanogens provide perhaps the best opportunity to study evolution because of their phyologenetic diversity and unique biochemistry. Today, the analysis of methanogens is at a threshold. Molecular-biological studies of these microorganisms are revealing more and more processes unique to this group, and in turn, studies of methanogens are providing new perspectives to the broader fields of biochemistry and molecular biology. This volume is the first book to be published on methanogenesis, and it will provide the reader with a comprehensive view of the field and point to future trends.

Available in PDF, EPUB and Kindle. Book excerpt: Biological nitrogen fixation provides more than 50% of the total annual input of the essential element nitrogen to world agriculture. Thus, it is of immense agronomic importance and critical to food supplies, particularly in developing countries. This book, with chapters authored by internationally renowned experts, provides a comprehensive and detailed account of the fascinating history of the process - including the surprising discoveries of molybdenum-independent nitrogenases and superoxide-dependent nitrogenase; a review of Man's attempts to emulate the biological process - most successfully with the commercially dominant Haber-Bosch process; and the current state of the understanding art with respect to the enzymes - called nitrogenases - responsible for biological nitrogen fixation. The initial chapters use a historical approach to the biological and industrial processes, followed by an overview of assay methodologies. The next set of chapters focuses on the classical enzyme, the molybdenum nitrogenase, and details its biosynthesis, structure, composition, and mechanism of action as well as detailing both how variants of its two component proteins are constructed by recombinant DNA technology and how computational techniques are being applied. The sophisticated chemical modelling of the metal-containing clusters in the enzyme is reviewed next, followed by a description of the two molybdenum-independent nitrogenases - first, the vanadium-containing enzyme and then the iron-only nitrogenase - together with some thoughts as to why they exist! Then follows an up-to-date treatment of the clearly "non-classical" properties of the superoxide-dependent nitrogenase, which more closely resembles molybdenum-containing hydroxylases and related enzymes, like nitrate reductase, that it does the other nitrogenases. Each chapter contains an extensive list of references. This book is the self-contained first volume of a comprehensive seven-volume series. No other available work provides the up-to-date and in-depth coverage of this series and this volume. This book is intended to serve as an indispensable reference work for all scientists working in this area, including agriculture and the closely related metals-in-biology area; to assist students to enter this challenging area of research; and to provide science administrators easy access to vital relevant information.
