This book reviews the wide range of products and applications of solid state fermentation as well as the development of this cultivation technology over the last years. In this book, readers will also learn about the challenges of solid state fermentation, including process management, reactor design, scale-up and the formation of process-specific products. Solid fermentation is a traditional cultivation technique of food technology and involves all cultivations of microorganisms on a solid substrate without free liquid phase. In the course of development of Biotechnology it was replaced by liquid cultivation mainly in the western countries. Over the past few years, solid-state fermentation is now becoming more important and has moved more back into focus. Especially, it is suitable for the cultivation of filamentous organisms, like ascomycetes and basidiomycetes, but also for various yeasts and bacteria. The products and applications of solid-state fermentation are as diverse as the microorganisms. They range from enzyme production to the production of antibiotics and pigments to the use in environmental technology and energy production.
Structural Resilience in Sewer Reconstruction: From Theory to Practice provides engineers with a balanced mixture of theory and practice.

What happens to a chemical once it enters the natural environment? How do its physical and chemical properties influence its transport, persistence, and partitioning in the biosphere? How do natural forces influence its distribution? How are the answers to these questions useful in making toxicological and epidemiological forecasts? Environmental Chemodynamics, Second Edition introduces readers to the concepts, tools, and techniques currently used to answer these and other critical questions about the fate and transport of chemicals in the natural environment. Like its critically acclaimed predecessor, its main focus is on the mechanisms and rates of movement of chemicals across the air/soil, soil/water, and water/air interfaces, and on how natural processes work to mobilize chemicals near and across interfaces—information vital to performing human and ecological risk assessments. Also consistent with the first edition, Environmental Chemodynamics, Second Edition is organized to accommodate readers of every level of experience. The first section is devoted to theoretical underpinnings and includes discussions of mass balance, thermodynamics, transport science concepts, and more. The second section concentrates on practical aspects, including the movement between bed-sediment and water, movement between soil and air, and intraphase chemical behavior. This revised and updated edition of Louis J. Thibodeaux's 1979 classic features new or expanded coverage of:
This Second Edition of Environmental Chemodynamics also includes twice as many references and 50% more exercises and practice problems.

Thirty years ago, the UN report Our Common Future placed sustainable development firmly on the international agenda. The Imperatives of Sustainable Development takes the ethical foundations of Our Common Future and builds a model that emphasizes three equally important moral imperatives - satisfying human needs, ensuring social justice, and respecting environmental limits. This model suggests sustainability themes and assigns thresholds to them, thereby defining the space within which sustainable development can be achieved. The authors accept that there is no single pathway to the sustainable development space. Different countries face different challenges and must follow different pathways. This perspective is applied to all countries to determine whether the thresholds of the sustainability themes selected have been met, now and in the past. The authors build on the extensive literature on needs, equity, justice, environmental science, ecology, and economics, and show how the three moral imperatives can guide policymaking. The Imperatives of Sustainable Development synthesizes past reasoning, summarizes the present debate, and provides a clear direction for future thinking. This book will be essential reading for everyone interested in the future of sustainable development and in the complex environmental and social issues involved.

The book examines a new concern in water quality policy, namely aquatic micropollutants. Micropollutants are chemicals detected in small concentrations in waterbodies today, originating from pharmaceuticals, cosmetics, or detergents, among others. Since the regulation of micropollutants is a fairly new issue, it has been largely neglected in social sciences. However, the search for appropriate solutions is of high political relevance at both the national and international levels, with many open questions arising that concern the most adequate governance structures and steering mechanisms. Solutions suitable for classical, macro-pollutants, such as nutrients, do not necessarily apply to micropollutants because of the diversity of compounds and sources, and for technical, financial, and societal reasons. The book addresses this knowledge gap by investigating the steering mechanisms at hand and their prospect for problem solving. In this regard, the research provides a systematic depiction and comparison of policy designs in place for the reduction of micropollutants in the Rhine basin. Moreover, the study yields insights into the governance structures in place, into actors' responsibilities and constellations, and policy processes regarding micropollutants. The study is furthermore embedded into broader theoretical questions of policy research. More precisely, this research is a contribution to policy analysis that aims to achieve more optimal policy results by providing for a better understanding of the nature of policy designs and the social mechanisms behind the choice of them. Despite the intrinsic aim of policy analysis at contributing to more optimal policy outcomes, there remains a lack of research regarding analytical tools that enable an ex-ante assessment of policy designs' problem-solving abilities. To explore such a research path, this book proposes a novel index of policy comprehensiveness for quantifying the prospective performance of policy designs in alleviating an underlying policy issue, e.g. reducing pollutants in waters. Furthermore, the book uncovers the social mechanisms behind policymaking and turns to the question: In which social settings is it possible to achieve a comprehensive policy design? Compared to purely micro-level explanations, the advantage of the network approach is that it goes beyond the mere aggregation of policy actors' attributes by taking into consideration actors' interdependencies. In order to take the network approach seriously, the study systematically links the structure of a policy network with comprehensive policy designs. Network concepts, such as coalition structure, interconnectedness, and belief similarity, are employed from policy change research here in order to explore the link between structural network characteristics and comprehensive policy design. By studying how network structures affect policy design, the book critically examines the explanatory value of the network approach.
This volume reviews the drinking water treatments in which AOPs display a high application potential. Firstly it reveals the typical supply sources and limitations of conventional technologies and critically reviews natural organic matter characterization and removal techniques, focusing mainly on AOP treatments. It then explores using AOPs for simultaneous inactivation/disinfection of several types of microorganisms, including highly resistant Cryptosporidium protozoa. Lastly, it discusses relevant miscellaneous topics, like the most promising AOP solid catalysts, the regime change of Fenton-like processes toward continuous reactors, the application of chemometrics for process optimization, the impact on disinfection byproducts and the tracing of toxicity during AOP treatments. This work is a useful reference for researchers and students involved in water technologies, including analytical and environmental chemistry, chemical and environmental engineering, toxicology, biotechnology, and related fields. It is intended to encourage industrial and public-health scientists and decision-makers to accelerate the application of AOPs as technological alternatives for the improvement of drinking water treatment plants. |
