Available in PDF, EPUB and Kindle. Book excerpt: Phosphorus in Environmental Technology: Principles and Applications, provides a definitive and detailed presentation of state-of-the-art knowledge on the environmental behaviour of phosphorus and its applications to the treatment of waters and soils. Special attention is given to phosphorus removal for recovery technologies, a concept that has emerged over the past 5-6 years. The book features an all-encompassing approach: the fundamental science of phosphorus (chemistry, geochemistry, mineralogy, biology), key aspects of its environmental behaviour and mobility, industrial applications (treatment, removal, recovery) and the principles behind such applications, novel biotechnologies and, importantly, it also addresses socio-economic issues which often influence implementation and the ultimate success of any new technology. A detailed subject index helps the reader to find their way through the different scientific and technological aspects covered, making it an invaluable reference work for students, professionals and consultants dealing with phosphorus-related environmental technologies. State-of-the-art knowledge on the behaviour of phosphorus and its applications to environmental science and technology. Covers all aspects of phosphorus in the environment, engineered and biological systems; an interdisciplinary text.
Download or read book Soil and Sediment Remediation written by Piet Lens and published by IWA Publishing. This book was released on 2005-09-30 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil and Sediment Remediation discusses in detail a whole set of remediative technologies currently available to minimise their impact. Technologies for the treatment of soils and sediments in-situ (landfarming, bioscreens, bioventing, nutrient injection, phytoremediation) and ex-situ (landfarming, bio-heap treatment, soil suspension reactor) will be discussed. The microbiological, process technological and socio-economical aspects of these technologies will be addressed. Special attention will be given to novel biotechnological processes that utilise sulfur cycle conversions, e.g. sulfur and heavy metal removal from soils. Also the potential of phytoremediation will be highlighted. In addition, treatment schemes for the clean-up of polluted megasites, e.g. harbours and Manufactured Gaswork Plants (MGP), will be elaborated. The aim of Soil and Sediment Remediation is to introduce the reader in: the biogeochemical characteristics of soil and sediments- new techniques to study soil/sediment processes (molecular probes, microelectrodes, NMR) clean up technologies for soils polluted with organic (PAH, NAPL, solvents) or inorganic (heavy metals) pollutants- preventative and remediative strategies and technologies available in environmental engineering novel process applications and bioreactor designs for bioremediation the impact of soil pollution on society and its economic importance.

Available in PDF, EPUB and Kindle. Book excerpt: This book examines the key aspects that will define future sustainable energy systems: energy supply, energy storage, security and limited environmental impacts. It clearly explains the need for an integrated engineering approach to sustainable energies, based on mathematical, biogeophysical, and engineering arguments. Resilient and efficient alternatives are compared to non-sustainable options. This book results from the collaboration of 50 international contributors.
Download or read book Mechanisms of Adaptation written by J.R. Spkatch and published by Elsevier. This book was released on 2014-04-24 with total page 615 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Bacteria: Volume VII: Mechanisms of Adaptation explores the mechanisms of bacterial adaptations and covers topics ranging from bacterial spores, cysts, and stalks to nitrogen fixation, bacterial chemotaxis, bacteriophage growth, and the structure and biosynthesis of bacterial cell walls. The roles of appendages and surface layers in adaptation of bacteria to their environment are also considered, along with cell division in Escherichia coli. This volume is comprised of nine chapters and begins with a discussion on the structure, properties, formation, and regulation of spores, cysts, and stalks in actinomycetes, blue-green bacteria, myxobacteria, Bacillus, Azotobacter, and Caulobacter. The reader is then introduced to the biochemistry, regulation, genetics, and evolution of nitrogen fixing in organisms; the receptors involved in bacterial chemotaxis and the nature of the sensing mechanism; the outer membrane of gram-negative bacteria; and bacterial functions involved in nutrient detection and acquisition. The roles played by organelles and surface layers in the adaptation of bacteria to their environment are also examined. The final chapter deals with the regulation of, and coordination between, the multitude of events involved in cell division in Escherichia coli. This monograph will be a useful resource for microbiologists, bacteriologists, biochemists, and biologists.

Download or read book Rhizobiology Molecular Physiology of Plant Roots written by Soumya Mukherjee and published by Springer Nature. This book was released on 2021-12-07 with total page 499 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the recent advancements in the role of various biomolecules in regulating root growth and development. Rhizobiology is a dynamic sub discipline of plant science which collates investigations from various aspects like physiology, biochemistry, genetic analysis and plant–microbe interactions. The physiology and molecular mechanisms of root development have undergone significant advancements in the last couple of decades. Apart from the already known conventional phytohormones (IAA, GA, cytokinin, ethylene and ABA), certain novel biomolecules have been considered as potential growth regulators or hormones regulating plant growth and development. Root phenotyping and plasticity analysis with respect to the specific functional mutants of each biomolecule shall provide substantial information on the molecular pathways of root signaling. Special emphasis provides insights on the tolerance and modulatory mechanisms of root physiology in response to light burst, ROS generation, agravitrophic response, abiotic stress and biotic interactions.
