The pace of progress in fermentation microbiology and biotechnology is fast and furious, with new applications being implemented that are resulting in a spectrum of new products, from renewable energy to solvents and pharmaceuticals Fermentation Microbiology and Biotechnology, Second Edition builds on the foundation of the original seminal work, extending its reach to reflect the multidisciplinary and expansive nature of fermentation research and advancements. While retaining valuable information from the previous edition including a brief history of the industry, as well as an overview of instrumentation and fermentor design, fermentation kinetics, and flux control analysis, the second edition addresses numerous topics that have risen to prominence in the past few years. New chapters explore the diverse array of microbial biosynthetic pathways currently used by the fermentation and pharmaceutical industries for the production of primary and secondary metabolites such as amino acids, vitamins, antibiotics, immunosuppressants, and anti-tumor agents. The authors also examine recent advances in enzyme and co-factor engineering and cell immobilization with respect to both novel drug development and improved yields from microbial processes. Beyond pharmaceuticals, this volume considers the emerging role of fermentation in the conversion of renewable resources to fine chemicals, as well as its potential use in converting lignocellulosic waste to ethanol. In addition, readers will also discover new chapters devoted to discussions of industrial issues such as modeling and sensor technology, as well as supervision and control in the fermentation process. The text is packed with examples and case studies from the industry, carefully chosen to illuminate and reinforce principles and methodology discussed in the chapters. Organized and written in a concise and lucid manner that requires only a general background in microbiology, this volume meets the needs

The abundance of organic pollutants found in wastewater affect urban surface waters. Traditional wastewater management technologies focus on the removal of suspended solids, nutrients and bacteria, however, new pollutants such as synthetic or naturally occurring chemicals are often not monitored in the environment despite having the potential to enter the environment and cause adverse ecological and human health effects. Collectively referred to as "emerging contaminants," they are mostly derived from domestic activities and occur in trace concentrations ranging from pico to micrograms per liter. Environmental contaminants are resistant to conventional wastewater treatment processes and most of them remain unaffected, causing contamination of receiving water. This in turn leads to the need for advanced wastewater treatment processes capable of removing environmental contaminants to ensure safe fresh water sources. This book provides an up-to-date overview of the current bioremediation strategies, including their limitations, challenges and their potential application to remove environmental pollutants. It also introduces the latest trends and advances in environmental bioremediation, and presents the state-of-the-art in biological and chemical wastewater treatment processes. As such, it will appeal to researchers and policy-makers, as well as undergraduate and graduate environmental sciences students.

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.

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.
