Microorganisms in Foods 8
by International Commission on Microbiological Specifications for FoodsMicroorganisms in Foods 8: Use of Data for Assessing Process Control and Product Acceptance is written by the International Commission on Microbiological Specifications for Foods with assistance from a limited number of consultants. The purpose of this book is to provide guidance on appropriate testing of food processing environments, processing lines, and finished product to enhance the safety and microbiological quality of the food supply. Microorganisms in Foods 8 consists of two parts. Part I, Principles of Using Data in Microbial Control, builds on the principles of Microorganisms in Foods 7: Microbiological Testing in Food Safety Management (2002), which illustrates how HACCP and Good Hygienic Practices (GHP) provide greater assurance of safety than microbiological testing, but also identifies circumstances where microbiological testing may play a useful role. Part II, Specific Applications to Commodities, provides practical examples of criteria and other tests and is an updated and expanded version of Part II of Microorganisms in Foods 2: Sampling for Microbiological Analysis: Principles and Specific Applications (2nd ed. 1986). Part II also builds on the 2nd edition of Microorganisms in Foods 6: Microbial Ecology of Food Commodities (2005) by identifying appropriate tests to evaluation the effectiveness of controls.

Microorganisms in Saline Environments: Strategies and Functions (Soil Biology #56)
by Ajit Varma Bhoopander GiriThis book gathers the latest findings on the microbial ecology of saline habitats, plant-microbe interactions under saline conditions, and saline soil reclamation for agricultural use. The content is divided into four main parts: Part I outlines the definition of salinity, its genesis and impacts, and microbial diversity in saline habitats. Part II deals with impact of salinity on microbial and plant life/health. Part III highlights plant – microbe interactions in saline environments, and Part IV describes strategies for mitigation and reclamation of saline soils. The salinization of arable land is steadily increasing in many parts of the world. An excessive concentration of soluble salts (salinity) in soils or irrigation water adversely affects plant growth and survival. This problem is exacerbated in arid and semiarid areas due to their low precipitation and high evaporation rates. In turn, poor management practices and policies for using river water for the irrigation of agriculture crops often lead to the secondary salinization of soils.Considering the growing demands of a constantly expanding population, understanding the microbial ecology and interactions under saline conditions and their implications for sustainable agriculture is of utmost importance. Providing both an essential review of the status quo and a future outlook, this book represents a valuable asset for researchers, environmentalists and students working in microbiology and agriculture..
Microorganisms in Sustainable Agriculture and Biotechnology
by Bhavdish Narain Johri Anil Prakash T. SatyanarayanaThis review of recent developments in our understanding of the role of microbes in sustainable agriculture and biotechnology covers a research area with enormous untapped potential. Chemical fertilizers, pesticides, herbicides and other agricultural inputs derived from fossil fuels have increased agricultural production, yet growing awareness and concern over their adverse effects on soil productivity and environmental quality cannot be ignored. The high cost of these products, the difficulties of meeting demand for them, and their harmful environmental legacy have encouraged scientists to develop alternative strategies to raise productivity, with microbes playing a central role in these efforts. One application is the use of soil microbes as bioinoculants for supplying nutrients and/or stimulating plant growth. Some rhizospheric microbes are known to synthesize plant growth-promoters, siderophores and antibiotics, as well as aiding phosphorous uptake. The last 40 years have seen rapid strides made in our appreciation of the diversity of environmental microbes and their possible benefits to sustainable agriculture and production. The advent of powerful new methodologies in microbial genetics, molecular biology and biotechnology has only quickened the pace of developments. The vital part played by microbes in sustaining our planet's ecosystems only adds urgency to this enquiry. Culture-dependent microbes already contribute much to human life, yet the latent potential of vast numbers of uncultured--and thus untouched--microbes, is enormous. Culture-independent metagenomic approaches employed in a variety of natural habitats have alerted us to the sheer diversity of these microbes, and resulted in the characterization of novel genes and gene products. Several new antibiotics and biocatalysts have been discovered among environmental genomes and some products have already been commercialized. Meanwhile, dozens of industrial products currently formulated in large quantities from petrochemicals, such as ethanol, butanol, organic acids, and amino acids, are equally obtainable through microbial fermentation. Edited by a trio of recognized authorities on the subject, this survey of a fast-moving field--with so many benefits within reach--will be required reading for all those investigating ways to harness the power of microorganisms in making both agriculture and biotechnology more sustainable.

Microparticle Dynamics in Electrostatic and Flow Fields (Springer Theses)
by Sheng ChenThis thesis proposes new approaches for modelling contacting interactions and electrostatic interactions between microparticles in the framework of the discrete element method and presents a systematic investigation on the agglomeration, migration and deposition of microparticles in presence of electrostatic and flow fields. It reports an exponential-form scaling for the size distribution of early-stage agglomerates in homogeneous isotropic turbulence and formulate the agglomeration and deagglomeration rates. The evolution of spherical clouds of charged particles that migrate under the action of an external electrostatic field is then investigated. Scaling laws of cloud radius and particle number density are obtained by solving a continuum convection equation. Finally, it investigates the deposition of charged particles on a flat plane and fibers. A dimensionless adhesion parameter is constructed to predict the structure of deposits. The temporal evolution of the deposit structure, particle capture efficiency, and the pressure drop are displayed with varying values of Coulomb repulsion and adhesion magnitudes.

Microphysics of Magnetic Reconnection in Near-Earth Space: Spacecraft Observations and Numerical Simulations (Springer Theses)
by Giulia CozzaniThis book presents recent advances in the physics of magnetic reconnection, investigated via both in situ spacecraft observations and fully kinetic numerical simulations. Magnetic reconnection is a fundamental process in plasma physics during which the topological reconfiguration of the magnetic field leads to energy conversion and particle energization. The book focuses on the physics of the electron diffusion region (EDR), a crucial region where the electrons are decoupled from the magnetic field and efficiently accelerated by the electric field. By using recent, high-resolution measurements provided by NASA’s Magnetospheric MultiScale Mission (MMS), the book investigates the structure of the EDR at the Earth’s magnetopause. The presented analysis provides evidence for an inhomogeneous and patchy EDR structure. The structure of the EDR appears to be more complex than the in laminar picture suggested by previous observations and simulations. Then, electrons dynamics in the EDR is studied using a novel, fully kinetic Eulerian Vlasov–Darwin model that has been implemented in the Vlasov–DArwin numerical code (ViDA), explained in detail in the book. Lastly, the book covers the testing of this new code, and investigates the contributions of the different terms in the generalized Ohm’s law within the EDR, highlighting the role of the electron inertia term.

Microplastic in the Environment: Pattern and Process (Environmental Contamination Remediation and Management)
by Michael S. BankThis open access book examines global plastic pollution, an issue that has become a critical societal challenge with implications for environmental and public health. This volume provides a comprehensive, holistic analysis on the plastic cycle and its subsequent effects on biota, food security, and human exposure. Importantly, global environmental change and its associated, systems-level processes, including atmospheric deposition, ecosystem complexity, UV exposure, wind patterns, water stratification, ocean circulation, etc., are all important direct and indirect factors governing the fate, transport and biotic and abiotic processing of plastic particles across ecosystem types. Furthermore, the distribution of plastic in the ocean is not independent of terrestrial ecosystem dynamics, since much of the plastic in marine ecosystems originates from land and should therefore be evaluated in the context of the larger plastic cycle. Changes in species size, distribution, habitat, and food web complexity, due to global environmental change, will likely alter trophic transfer dynamics and the ecological effects of nano- and microplastics. The fate and transport dynamics of plastic particles are influenced by their size, form, shape, polymer type, additives, and overall ecosystem conditions. In addition to the risks that plastics pose to the total environment, the potential impacts on human health and exposure routes, including seafood consumption, and air and drinking water need to be assessed in a comprehensive and quantitative manner. Here I present a holistic and interdisciplinary book volume designed to advance the understanding of plastic cycling in the environment with an emphasis on sources, fate and transport, ecotoxicology, climate change effects, food security, microbiology, sustainability, human exposure and public policy.

by Maulin P. Shah Günay Yıldız TöreThis book systematically summarizes the occurrence and source of MPs through various municipal and industrial wastewaters. It covers the type of MPs, its effects on human health and climate, and emerging detection and treatment methods. Plastics are one of the refractory pollutants produced in many and varied forms using chemistry and materials science. Microplastics (MPs), which are formed as a result of plastics breaking down into small pieces, are a new indicator that indicates that the plastic footprint of humans is growing today and this has become a risk for the general living health and sustainable environment. Depending on the point of use, they are either directly released to the air, water, and soil, or they break down into secondary MPs in the environment where they are discharged. Especially by means of domestic wastewater, plenty of MPs enter the sewage system on a daily basis. Therefore, wastewater treatment plants (WWTPs) draw attention as an important source of MP pollution in coastal or surface waters such as sea, lake, and river. There is still a limited number of studies on MPs in the literature and it has become the focus of many researchers around the world. This book mainly focuses on the behavior of microplastics in the wastewaters. The book has 12 chapters and throughout each chapter, it presents the fate and effect of MPs, quantitative and qualitative analyses of MPs in wastewaters and treatment of MPs through conventional and advanced wastewater treatment technologies, effects of MPs on human health and climate change and also evaluates the legal restrictions for MPs pollution in the environment and will also be examined in all details.
