Available in PDF, EPUB and Kindle. Book excerpt: As for the preceding four International Symposia on Nitrogen Fixation, held in Pullman, Washington USA (1974); Salamanca, Spain (1976); Madison, Wisconsin, USA (1978); and Canberra, Australia (1980), the 5th Symposium held from August 28 - September 3, 1983 in Noordwijkerhout, The Netherlands, received the gene rous support of the Charles F. Kettering Foundation Research Laboratory and the Tennessee Valley Authority. This support has helped research progress in this broad field of science by offering a forum both for the exchange of ideas and for scientific summary and discussion as captured over the last 10 years in each of the four books published previously. Although all previous meetings were well attended, the present conference was the largest so far. 550 scien tists from 60 different countries attended the "Leeuwenhorst Conference", re presenting the many different disciplines actively involved in research in this field: chemists, biochemists, molecular biologists, geneticists, microbiologists, plant physiologists, agriculturalists. A large number of them had to go through a difficult period to raise the necessary funds to attend. In addition, a parallel meeting of "policymakers" from Southeast Asia, Africa and South America was held under the auspices of Crosscurrents International Institute, Dayton, OR, USA and the United Nations University, Tokyo, Japan. These participants attended some of the scientific sessions to benefit from the vision of a number of scientists at the symposium.

Available in PDF, EPUB and Kindle. Book excerpt: This volume constitutes the proceedings of an international meeting held from June 28 to July 1, 1981, at Zif, Zentrum far Interdisziplin~re Forschung an der Universit~t Bielefeld, West Germany. The meeting was one of a continuing series organized through Zif on topics which transcend the boundaries of the traditional academic disciplines. The almost exponentially growing area of nitrogen fixation research fits this criterion completely. It is, however, so broad that we oriented and focused the meeting on just the chemical, biochemical, and genetic aspects to maximize the interaction among the participants and to produce a volume which would serve as a reference source for the involved researcher, the newly interested scientist and those with a more casual interest. The meeting was generously supported by Zif, the Westf~lisch Lippische Universit~tsgesellschaft, and the Fonds der Chemischen Industrie. We sincerely thank these organizations for their generosity and interest and for recognizing the importance of nitrogen fixation research for the future of mankind.

Download or read book Symbiotic Nitrogen Fixation written by P. Graham and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past three decades there has been a large amount of research on biological nitrogen fixation, in part stimulated by increasing world prices of nitrogen-containing fertilizers and environmental concerns. In the last several years, research on plant--microbe interactions, and symbiotic and asymbiotic nitrogen fixation has become truly interdisciplinary in nature, stimulated to some degree by the use of modern genetic techniques. These methodologies have allowed us to make detailed analyses of plant and bacterial genes involved in symbiotic processes and to follow the growth and persistence of the root-nodule bacteria and free-living nitrogen-fixing bacteria in soils. Through the efforts of a large number of researchers we now have a better understanding of the ecology of rhizobia, environmental parameters affecting the infection and nodulation process, the nature of specificity, the biochemistry of host plants and microsymbionts, and chemical signalling between symbiotic partners. This volume gives a summary of current research efforts and knowledge in the field of biological nitrogen fixation. Since the research field is diverse in nature, this book presents a collection of papers in the major research area of physiology and metabolism, genetics, evolution, taxonomy, ecology, and international programs.
Download or read book Nitrogen Fixation in Agriculture Forestry Ecology and the Environment written by Dietrich Werner and published by Springer Science & Business Media. This book was released on 2006-01-20 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainability has a major part to play in the global challenge of continued development of regions, countries, and continents all around the World and biological nitrogen fixation has a key role in this process. This volume begins with chapters specifically addressing crops of major global importance, such as soybeans, rice, and sugar cane. It continues with a second important focus, agroforestry, and describes the use and promise of both legume trees with their rhizobial symbionts and other nitrogen-fixing trees with their actinorhizal colonization. An over-arching theme of all chapters is the interaction of the plants and trees with microbes and this theme allows other aspects of soil microbiology, such as interactions with arbuscular mycorrhizal fungi and the impact of soil-stress factors on biological nitrogen fixation, to be addressed. Furthermore, a link to basic science occurs through the inclusion of chapters describing the biogeochemically important nitrogen cycle and its key relationships among nitrogen fixation, nitrification, and denitrification. The volume then provides an up-to-date view of the production of microbial inocula, especially those for legume crops.

Download or read book Advances in Biology and Ecology of Nitrogen Fixation written by Takuji Ohyama and published by BoD – Books on Demand. This book was released on 2014-01-29 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological nitrogen fixation has essential role in N cycle in global ecosystem. Several types of nitrogen fixing bacteria are recognized: the free-living bacteria in soil or water; symbiotic bacteria making root nodules in legumes or non-legumes; associative nitrogen fixing bacteria that resides outside the plant roots and provides fixed nitrogen to the plants; endophytic nitrogen fixing bacteria living in the roots, stems and leaves of plants. In this book there are 11 chapters related to biological nitrogen fixation, regulation of legume-rhizobium symbiosis, and agriculture and ecology of biological nitrogen fixation, including new models for autoregulation of nodulation in legumes, endophytic nitrogen fixation in sugarcane or forest trees, etc. Hopefully, this book will contribute to biological, ecological, and agricultural sciences.
Download or read book Microbiology of Tropical Soils and Plant Productivity written by Y.R. Dommergues and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is an established fact that we must continually increase and improve agricultural production if we are to meet even the minimum requirements of a growing popu lation for food, shelter, and fuel. In recent years, the introduction of new plant varieties and the extensive use of fertilizers have effectively increased crop yields, but intensifying agricultural methods has often led to depleting soil fertility. Two examples of the harmful consequences of intensive farming practices are the loss of up to 2.5 cm of topsoil every 15 years in the United States through erosion and the alarming rise in environmental pollution through widespread use of pesticides. Countless other processes affecting the activity of soil micro flora and the inter actions between microorganisms and plants may pose an equal danger to soil equilibrium, but their potential hazards are often overlooked because of an insufficient understanding of soil microbiology on the part of scientists. In the first published study of its kind, the authors of this book have attempted to address major aspects of the microbial activity of soil in the tropics. Tropical conditions serve as an ideal context for a discussion of soil microbiology, since biological processes in the soil are particularly active in tropical environments in comparison to other settings and in relation to physical and chemical processes.

Download or read book Sulfur written by A. Müller and published by Elsevier. This book was released on 2016-01-26 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sulfur: Its Significance for Chemistry, for the Geo-, Bio- and Cosmosphere and Technology focuses on the significance of sulfur for chemistry, geosphere, biosphere, cosmosphere, and technology. Topics covered range from the geochemistry and natural cycle of sulfur to the role of sulfur in "black powder". Organometallic sulfur compounds, thiolates, and the spectroscopic effects of sulfur chemistry are also discussed. Comprised of 21 chapters, this volume begins with an introduction to elemental sulfur and related homocyclic compounds and ions, focusing on their preparation, molecular and crystal structures, molecular spectra, and thermodynamic properties. Subsequent chapters deal with the origin and natural cycle of sulfur in the earth's crust; the role of sulfur in the reactions of exploding gunpowder; the use of sulfur in artwork; and developments in the field of organic sulfur chemistry. The catalytic properties of metal complexes of sulfur and sulfur-nitrogen compounds are also examined, along with the synthetic aspects of sulfido-complexes of molybdenum and tungsten. The final section is devoted to the role of sulfur in microbiology, biochemistry, and medicine. This monograph will be useful to students, practitioners, and researchers in the field of inorganic chemistry, as well as those who are interested in sulfur and its compounds.
Download or read book Catalysts for Nitrogen Fixation written by Barry E. Smith and published by Springer Science & Business Media. This book was released on 2013-03-20 with total page 351 pages. 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.
Download or read book Forest Ecosystems in the Alaskan Taiga written by K. van Cleve and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: The information presented in this book is the result of combined research efforts of scientists at the University of Alaska, Fairbanks, the Institute of Northern Forestry, USDA Forest Service, and the Systems Ecology Research Group, San Diego State University. The objective of the volume is to present a synthetic overview of structure and function of taiga forest ecosystems in interior Alaska. The data base for this work has appeared in earlier published articles including the special issue of the Canadian Journal of Forest Research Volume 13:5 (1983). Stimulus for this book was a conference held in Fairbanks from June 10-14, 1983. The papers presented at the conference were fore runners of the chapters in this book. We invited 19 scientists from North America and England to critique our research and synthesis efforts. Six of these people were asked to write introductory chapters for each section of the book. Formal presentation sessions, combined with field trips to research sites, introduced the invitees to the primary and secondary successional ecosystems with which we were dealing. A major wildfire, only 24 km from the University campus, was contained the week prior to the conference and one field trip provided graphic evidence of fire impact in subarctic forests. The conference conveners regretted that it was not possible to host a similar meeting during synthesis efforts in mid-January.
