Available in PDF, EPUB and Kindle. Book excerpt: Microorganisms have simultaneously served and assaulted man throughout history. Man is totally dependent on some microbes for life processes, while remaining subject to the destructive capacities of others in diseases not yet conquered.Microbes can be marshaled to aid in solving many important global problems including food shortages, resource recovery and reuse, energy shortages, and pollution. Microbiology is particularly suited to make important contributions to human needs in developing countries, yet it has received comparatively little attention. The range of possible applications covers uses by individuals and industries in rural settings, villages, and cities.This book covers examples of microbial processes that may be useful in developing countries. Although many of these processes may not have a direct and immediate use, their scope and diversity should serve to indicate the strong potential for microbial applications.

Download or read book Nitrogen in the Environment Sources Problems and Management written by R.F. Follett and published by Gulf Professional Publishing. This book was released on 2001-12-03 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen in the Environment: Sources, Problems, and Management is the first volume to provide a holistic perspective and comprehensive treatment of nitrogen from field, to ecosystem, to treatment of urban and rural drinking water supplies, while also including a historical overview, human health impacts and policy considerations. It provides a worldwide perspective on nitrogen and agriculture. Nitrogen is one of the most critical elements required in agricultural systems for the production of crops for feed, food and fiber. The ever-increasing world population requires increasing use of nitrogen in agriculture to supply human needs for dietary protein. Worldwide demand for nitrogen will increase as a direct response to increasing population. Strategies and perspectives are considered to improve nitrogen-use efficiency. Issues of nitrogen in crop and human nutrition, and transport and transformations along the continuum from farm field to ground water, watersheds, streams, rivers, and coastal marine environments are discussed. Described are aerial transport of nitrogen from livestock and agricultural systems and the potential for deposition and impacts. The current status of nitrogen in the environment in selected terrestrial and coastal environments and crop and forest ecosystems and development of emerging technologies to minimize nitrogen impacts on the environment are addressed. The nitrogen cycle provides a framework for assessing broad scale or even global strategies to improve nitrogen use efficiency. Growing human populations are the driving force that requires increased nitrogen inputs. These increasing inputs into the food-production system directly result in increased livestock and human-excretory nitrogen contribution into the environment. The scope of this book is diverse, covering a range of topics and issues from furthering our understanding of nitrogen in the environment to policy considerations at both farm and national scales.

Download or read book Phytochemical Diversity and Redundancy in Ecological Interactions written by John T. Romeo and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diversity within and among living organisms is both a biological impera tive and a biological conundrum. Phenotypic and genotypic diversity is the critical currency ofecological interactions and the evolution of life. Thus, it is not unexpected to find vast phytochemical diversity among plants. However, among the most compelling questions which arise among those interested in ecological phytochemistry is the extent, nature, and reasons for the diversity of chemieals in plants. The idea that natural products (secondary metabolites) are accidents of metabolism and have no biological function is an old one which has resurfaced recently under a new term "redundancy. " Redundancy in the broader sense can be viewed as duplication of effort. The co-occurrence of several classes of phytochemieals in a given plant may be redundancy. Is there unnecessary duplication of chemical defense systems and ifso, why? What selective forces have produced this result? On the other hand, why does the same compound often have multiple functions? At a symposium of the Phytochemical Society of North America held in August 1995, in Sault Ste. Marie, Ontario, Canada, the topic "Phytochernical Redundancy in Ecological Interactions" was discussed. The chapters in this volume are based on that symposium. They both stimulate thought and provide some working hypotheses for future research. It is being increasingly recognized that functional diversity and multiplicity of function of natural products is the norm rather than the exception.

Download or read book Process Control for Biological Nutrient Removal Processes in Fluidized Beds Treating Low Carbon to Nitrogen Municipal Wastewater written by Joseph Donohue and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional wastewater treatment techniques - utilizing microorganisms to remove organics and nutrients (i.e. nitrogen and phosphorus) from a water stream and partially incorporate them into their cell structure - struggle to adapt with increased urbanization due to land and infrastructure requirements. The circulating fluidized-bed bioreactor (CFBBR) was developed as a way to provide biological treatment in an urbanized area by cultivating high-density bacteria on an inert media. The technology operates as a pre-anoxic nitrification/denitrification wastewater treatment process. The system is initially loaded with media, providing a platform for microbial growth. Internal recycle streams in the system provide the energy to fluidize the media - increasing mass transfer and accelerating microbial growth and pollutant removal rates. A pilot-scale CFBBR unit operated in Guangzhou, China, at an organic loading rate of 0.50 kg COD/day and a nitrogen loading rate of 0.075 kg N/day, was able to achieve a 93% reduction in carbon and an 88% reduction in nitrogen. In addition, an innovative sensor network was constructed from open source hardware to monitor and adjust dissolved oxygen (DO) levels inside a 15 L lab-scale partial nitrification fluidized-bed. The treatment strategy for this biological process was to create reactor conditions that favour nitrifying bacteria that convert ammonia to nitrite, called ammonia oxidizing bacteria (AOB), over nitrifying bacteria that convert nitrite to nitrate, called nitrite oxidizing bacteria (NOB). The CFBBR, by virtue of its unique abilities to control biofilm thickness and accordingly biological solids retention time, offers significant advantages over other emerging nitrogen removal processes. The control system was designed to automatically adjust the air flow to the bioreactor to maintain a DO level of approximately 1 mg/L, conditions that favour AOBs activity over NOBs. The unit operated continuously for 40 days as the bioreactor was fed with 200 mg/L of synthetic ammonia wastewater (devoid of carbon) to a maximum nitrogen loading rate of 6 g NH4-N/day. The control system was able to maintain an ambient DO level of 1.30 mg/L. At this loading rate, the effluent nitrate concentration was approximately 5% of the influent feed - indicating low NOB populations in the reactor.

Available in PDF, EPUB and Kindle. Book excerpt: The globally important nature of wetland ecosystems has led to their increased protection and restoration as well as their use in engineered systems. Underpinning the beneficial functions of wetlands are a unique suite of physical, chemical, and biological processes that regulate elemental cycling in soils and the water column. This book provides an in-depth coverage of these wetland biogeochemical processes related to the cycling of macroelements including carbon, nitrogen, phosphorus, and sulfur, secondary and trace elements, and toxic organic compounds. In this synthesis, the authors combine more than 100 years of experience studying wetlands and biogeochemistry to look inside the black box of elemental transformations in wetland ecosystems. This new edition is updated throughout to include more topics and provide an integrated view of the coupled nature of biogeochemical cycles in wetland systems. The influence of the elemental cycles is discussed at a range of scales in the context of environmental change including climate, sea level rise, and water quality. Frequent examples of key methods and major case studies are also included to help the reader extend the basic theories for application in their own system. Some of the major topics discussed are: Flooded soil and sediment characteristics Aerobic-anaerobic interfaces Redox chemistry in flooded soil and sediment systems Anaerobic microbial metabolism Plant adaptations to reducing conditions Regulators of organic matter decomposition and accretion Major nutrient sources and sinks Greenhouse gas production and emission Elemental flux processes Remediation of contaminated soils and sediments Coupled C-N-P-S processes Consequences of environmental change in wetlands# The book provides the foundation for a basic understanding of key biogeochemical processes and its applications to solve real world problems. It is detailed, but also assists the reader with box inserts, artfully designed diagrams, and summary tables all supported by numerous current references. This book is an excellent resource for senior undergraduates and graduate students studying ecosystem biogeochemistry with a focus in wetlands and aquatic systems.
