The formation of atmospheric nitrogen gas by denitrifying bacteria may represent a significant nutrient sink in natural ecosystems. The rate of denitrification has often been difficult to measure in situ, however, and new methodologies should stimulate research on distribution of activity in space and time. The load of fertilizer nitrogen in modem agriculture has led to increasing nutrient reservoirs in recipient subsoils, aquifers, inland waters and coastal seas. By its conversion of nitrate to atmospheric nitrogen, bacterial denitrification is the only biological process to potentially reduce the impact of increasing nutrient loadings by fertilizer nitrogen in the environment. As part of a...
The 1st International Workshop on Acinetobacter was held on 6th September, 1986, in Manchester, England, in association with the 14th International Congress of Microbiology. That occasion was so well attended and productive that there were soon discussions about how, when and where the next meeting should be held. This time, however, there was sufficient confidence to think of a more substantial meeting and to plan for the proceedings to be published. It emerged that there was wide agreement that the time was ripe to take stock of the entire biology of Acinetobacter: its occurrence and taxonomy; its molecular biology, biochemistry and physiology; its clinical importance and its industrial an...
This book focuses on holistic approaches to sustainability in all sectors of building, infrastructure, and energy to achieve a best-balanced global energy, building, infrastructure, transportation, and water technology (EBITW) system using a series of innovative research and implementation solutions. The goal of this book is to define the context for proactive consideration of scientific theories and practical technical applications of sustainable development, following main seven themes: Renewable Energy Technology, Advanced Building Design Technology, Innovative Infrastructure and Transportation Engineering, Clean Water and Sanitation, Sustainable Urban and Rural Development, Clean Environment, and Sustainable Planet; which are very much interconnected to secure the global equilibrium. The book is prepared for a wide audience including researchers, field engineers, and students.
The six years that have passed since the publication of the first edition have brought significant advances in both biofilm research and biofilm engineering, which have matured to the extent that biofilm-based technologies are now being designed and implemented. As a result, many chapters have been updated and expanded with the addition of sections reflecting changes in the status quo in biofilm research and engineering. Emphasizing process analysis, engineering systems, biofilm applications, and mathematical modeling, Fundamentals of Biofilm Research, Second Edition provides the tools to unify and advance biofilm research as a whole. Retaining the goals of the first edition, this second edition serves as: A compendium of knowledge about biofilms and biofilm processes A set of instructions for designing and conducting biofilm experiments A set of instructions for making and using various tools useful in biofilm research A set of computational procedures useful in interpreting results of biofilm research A set of instructions for using the model of stratified biofilms for data interpretation, analysis, and biofilm activity prediction
Scientists from 24 countries who participated in the ~ Symposium on Candida and Candidamycosis, 24-28 April 1989, Antalya, Turkey, have made important contributions to a better understanding of Candida and its infections - by their presence, presentations and discussions in the meeting. The Turkish Microbiological Society, organizing the Symposium in the name of the Federation of European Microbiological Societies (FEMS), thanks all participants for realising this important meeting on such an important subject. In this book the full manuscripts of invited and free papers of the meeting are presented. The Editors extend their sincere thanks to all contributors of papers; to FEMS for encouraging and undertaking the arrangements for publication; to Ege University Publishing House for printing; to Plenum Publishing Company for publishing; and to all colleagues and friends who with their help contributed to this book. The Editors wish that this volume would contribute to a better understanding of Candida and its infections by colleagues working and/or interested in mycology and mycotic diseases.
The remarkable scientific story of how Earth became an oxygenated planet The air we breathe is twenty-one percent oxygen, an amount higher than on any other known world. While we may take our air for granted, Earth was not always an oxygenated planet. How did it become this way? Donald Canfield—one of the world's leading authorities on geochemistry, earth history, and the early oceans—covers this vast history, emphasizing its relationship to the evolution of life and the evolving chemistry of the Earth. Canfield guides readers through the various lines of scientific evidence, considers some of the wrong turns and dead ends along the way, and highlights the scientists and researchers who have made key discoveries in the field. Showing how Earth’s atmosphere developed over time, Oxygen takes readers on a remarkable journey through the history of the oxygenation of our planet.
Nitrogen constitutes 78% of the Earth’s atmosphere and inevitably occupies a predominant role in marine and terrestrial nutrient biogeochemistry and the global climate. Callous human activities, like the excessive industrial nitrogen fixation and the incessant burning of fossil fuels, have caused a massive acceleration of the nitrogen cycle, which has, in turn, led to an increasing trend in eutrophication, smog formation, acid rain, and emission of nitrous oxide, which is a potent greenhouse gas, 300 times more powerful in warming the Earth’s atmosphere than carbon dioxide. This book comprehensively reviews the biotransformation of nitrogen, its ecological significance and the consequences of human interference. It will appeal to environmentalists, ecologists, marine biologists, and microbiologists worldwide, and will serve as a valuable guide to graduates, post-graduates, research scholars, scientists, and professors.
State-of-the-art update on methods and protocols dealing with the detection, isolation and characterization of macromolecules and their hosting organisms that facilitate nitrification and related processes in the nitrogen cycle as well as the challenges of doing so in very diverse environments.

Advances in Microbial Ecology was established by the International Com mittee on Microbial Ecology (ICOME) to provide a means for in-depth, critical, and even provocative reviews to emphasize current trends in the rapidly expanding area of microbial ecology. Advances in Microbial Ecol ogy is now recognized as a major source of information and inspiration both for practicing and for prospective microbial ecologists. The majority of reviews published in Advances have been prepared by leaders in par ticular areas following invitations provided by the Editorial Board. Although the Board intends to continue its policy of soliciting reviews, individual microbial ecologists are encouraged to submit...
