Most bioactive compounds have antioxidant activity, particularly tocochromanols, phenolics (flavonoids and phenolic acids), methylxantines and capsaicinoids. Some of these compounds have also other properties important for human health. For example, vitamin E protects against oxidative stress, but it is also known for its "non-antioxidant" functions, including cell signalling and antiproliferation. Selenium compounds and indoleamins are the components of the antioxidant enzymes. Selenium makes vitamin E acquisition easier and controls its physiological functions. In taking part in enzymatic reactions and protecting the cell against free radicals, selenium shows immunomodulative, antiphlogistic, and antiviral activity. Capsaicinoids possess not only antioxidant, but also antibacterial, analgesic, weight-reducing and thermoregulation properties. Studies have also demonstrated their gastroprotective and anticancer properties. Analytical Methods in the Determination of Bioactive Compounds and Elements in Food explores both the influence of particular compounds on human health and the methods used for their determination. Chapters describe various aspects of food and plant analysis, including chromatographic and non-chromatographic approaches as well as hyphenated techniques. Readers of this book will gain a comprehensive understanding of the important groups of bioactive compounds relevant to human health.

This book provides a comprehensive examination of the role of gut microbiome/microflora in nutrition, metabolism, disease prevention and health issues, including farm animal health and food value, and human gastrointestinal health and immunity. Indigenous microbiotas, particularly the gut microflora/microbiome, are an essential component in the modern concept of human and animal health. The diet and lifestyle of the host and environment have direct impact on gut microflora and the patterns of gut microbial colonization associated with health and diseases have been documented. Contributing authors cover the impact of gut microbiome in farm animal health, and explore the possibility of modulating the human gut microbiome with better animal products to prevent human diseases, including endemic and emerging diseases such as obesity, cancer and cardiac diseases. Dieting plan and control methods are examined, with attention paid to balance dieting with natural food and drink components. In addition, the role of gut microbiota in enteric microbial colonization and infections in farm animals is also discussed. The volume also explores the possibility of improving human health by modulating the microbiome with better food, including bio-active foods and appropriate forms of intake. Throughout the chapters, authors examine cutting edge research and technology, as well as future directions for better practices regarding emerging issues, such as the safety and production of organic food.

This book addresses the shelf life of foods, a key factor in determining how food is distributed and consequently where and when different food products are available for consumption. Shelf life is determined by several factors, including microbiological, chemical, physical, and organoleptic deterioration. Often these factors are interrelated and interdependent. The editors of this volume focus specifically on the microbial factors related to shelf life of perishable foods and food commodities. This allows for more detailed coverage of foodborne bacterial pathogens and spoilage microorganisms of concern. The initial part of the book covers the why and how of shelf life determination as well as the specific microbial pathogens and spoilage microorganisms of concern for perishable foods. Contributors address topics such as the techniques utilized for determination of shelf life, the frequency of shelf life testing for different products, the interpretation of data to make shelf life determinations, and management of shelf life of food products from the perspective of the food producer, distributor, retailer, and regulator. Three key areas impacting shelf life are addressed in detail: sanitation, processing, and packaging. The sanitation chapter explains the necessary components of cleaning and sanitizing to assure a hygienic processing environment and why that is critical to shelf life control. Traditional processing procedures are reviewed and advanced processing technologies are explored. Materials used in food packaging and the utilization of traditional and activated food packaging by product type are covered in detail. The latter two chapters of the book delve into newer techniques of analysis and explore the microbiome of food products. Implications of microbial ecology and microbial quantification in food products are discussed in chapters on genomics and in the changing dogma of meat shelf life. The primary audience for this work includes food industry quality and food safety technicians, managers, directors, and executives responsible for shelf life. Academicians and governmental researchers involved in research and teaching about food safety and quality will also find the material relevant and useful.

This book represents the proceedings of a Satellite Symposium of the XIth International Congress of Biochemistry on "Control of Membrane Fluidity" which was held on July 7, 1979 at the Charles H. Best Institute, University of Toronto, Toronto, Canada. The meeting was organized by M. Kates and A. Kuksis and was supported by the International Congress of Biochemistry. The purpose of the meeting was to review recent progress in many different areas of investigation bearing on the role of lipids in the structural and functional property of the cell membrane commonly referred to as fluidity. The aim was to emphasize the factors controlling membrane fluidity as studied in appropriate in vitro and in vivo experiments. The Symposium included invited review papers and short papers offered by discussants. In assem. bling the book no distinction has been made between the two types of presentations, nor has any significance been attached to the chronological order of their presentation in the Symposium. As a result it was possible to provide a much more coherent and continuous presentation than that available at the meeting."

The increased demand due to anthropogenic activity leads to emerging contaminants, resulting in a substantial environmental hazard. The long-term presence and exposure of contaminants lead to severe negative impacts on the environment, humans, and other life forms. Hence, emerging contaminants in the environment is a worldwide concern, and new technologies to mitigate these contaminants are being developed. This book covers the source, occurrence, toxicity, and detection techniques of a wide range of emerging contaminants. This collection also discusses the scope and applications of diverse techniques, including Bio/Phyto and Nano-remediation technologies, to mitigate the emerging contaminants; along with their sustainability issue and prospects. As a result, this book appears to provide insight into several modern and environmentally friendly waste management options, the possibility to minimize and lessen the effects of contaminants, and striving to lower toxicological endpoints to assure environmental safety. This book delivers the most recent advancements by prominent specialists in environmental sciences to academics, researchers, students, and practitioners interested in the identification and eradication of emerging pollutants from the environment.

It is widely acknowledged that life has adapted to its environment, but the precise mechanism remains unknown since Natural Selection, Descent with Modification and Survival of the Fittest are metaphors that cannot be scientifically tested. In this unique text, invertebrate and vertebrate biologists illuminate the effects of physiologic stress on epigenetic responses in the process of evolutionary adaptation from unicellular organisms to invertebrates and vertebrates, respectively. This book offers a novel perspective on the mechanisms underlying evolution. Capacities for morphologic alterations and epigenetic adaptations subject to environmental stresses are demonstrated in both unicellular and multicellular organisms. Furthermore, the underlying cellular-molecular mechanisms that mediate stress for adaptation will be elucidated wherever possible. These include examples of 'reverse evolution' by Professor Guex for Ammonites and for mammals by Professor Torday and Dr. Miller. This provides empiric evidence that the conventional way of thinking about evolution as unidirectional is incorrect, leaving open the possibility that it is determined by cell-cell interactions, not sexual selection and reproductive strategy. Rather, the process of evolution can be productively traced through the conservation of an identifiable set of First Principles of Physiology that began with the unicellular form and have been consistently maintained, as reflected by the return to the unicellular state over the course of the life cycle.

During the past five years increased awareness of environmental contamination by nitroaromatic compounds has led to a dramatic increase in research on their biodegradation. The resulting discoveries have markedly extended our understanding of degradation mecha nisms and pathways in bacteria and fungi. Futhermore, this new basic knowledge promises the development of field applications of biodegradation systems for nitroaromatic com pounds. In May of 1994, an International Symposium on the Biodegradation of Nitro aromatic Compounds was held in Las Vegas, Nevada. This symposium brought together the scientists at the frontiers of research into the biodegradation of nitro aromatic compounds. The invited speakers were asked to review their area of expertise and write a critical, comprehensive synthesis of their work and related work by others. This book is the result of their efforts. The emphasis of the reviews is on basic research in biodegradation and biotransfor mation. Therefore, the reactions of nitroaromatic compounds in plants, animals, bacteria, fungi, soil, and even nonbiological systems are considered. The goal of the work is to provide the reader with an appreciation of the tremendous range of possibilities for metabolism of aromatic nitro compounds and the experimental approaches used to understand them. This volume should be of interest to biochemists, microbiologists, engineers, toxicologists, and anyone interested in the behavior of synthetic chemicals in the environment or in living systems. Furthermore, a variety of commercial applications can be envisioned for some of the reactions described here."

Algae are simple, primitive, heterogeneous, autotrophic, eukaryotic or prokaryotic organisms that lead a symbiotic, parasitic or free-living mode of life. Microalgae and macroalgae possess great potential in various fields of application. Microalgae are ubiquitous and extremely diverse microorganisms that can accumulate toxic contaminants and heavy metals from wastewater, making them a superior candidate to become a powerful nanofactory. Algae were discovered to reduce the presence of metal ions, and afterwards aid in the biosynthesis of nanoparticles. Since algae-mediated biogenic nanoparticles are eco-friendly, cost-effective, high-yielding, speedy and energy-efficient, a large number of studies have been published on them in the last few years. This book focuses on recent progress on the utilization of algae for the synthesis of nanoparticles, their characterization and the possible mechanisms involved. Bioprospecting Algae for Nanosized Materials describes the synthesis of algal nanomaterials and its application in various fields for sustainable development. This book outlines the procedures to prepare phyconanomaterials, techniques to utilize the nanomaterials, and applications in agriculture, environment and medicine.

This open access book offers the first comprehensive account of the pan-genome concept and its manifold implications. The realization that the genetic repertoire of a biological species always encompasses more than the genome of each individual is one of the earliest examples of big data in biology that opened biology to the unbounded. The study of genetic variation observed within a species challenges existing views and has profound consequences for our understanding of the fundamental mechanisms underpinning bacterial biology and evolution. The underlying rationale extends well beyond the initial prokaryotic focus to all kingdoms of life and evolves into similar concepts for metagenomes, phenomes and epigenomes. The book's respective chapters address a range of topics, from the serendipitous emergence of the pan-genome concept and its impacts on the fields of microbiology, vaccinology and antimicrobial resistance, to the study of microbial communities, bioinformatic applications and mathematical models that tie in with complex systems and economic theory. Given its scope, the book will appeal to a broad readership interested in population dynamics, evolutionary biology and genomics.

Achieving environmental sustainability with rapid industrialization is a major challenge of current scenario worldwide. As globally evident, industries are the key economic drivers, but are also the major polluters as untreated/partially treated effluents discharged from the industries is usually thrown into the aquatic resources and also dumped unattended. Industrial effluents are considered as the major sources of environmental pollution as these contains highly toxic and hazardous pollutants, which reaches far off areas due to the medium of dispersion and thus, create ecological nuisance and health hazards in living beings. Hence, there is an urgent to find ecofriendly solution to deal with industrial waste, and develop sustainable methods for treating/detoxifying wastewater before its release into the environment. Being a low cost and eco-friendly clean technology, bioremediation can be a sustainable alternative to conventional remediation technologies for treatment and management of industrial wastes to protect public health and environment. Therefore, this book (Volume I) covers the bioremediation of different industrial wastes viz. tannery wastewater, pulp and paper mill wastewater, distillery wastewater, acid mine tailing wastes, and many more; which are lacking in a comprehensive manner in previous literature at one place. A separate chapter dedicated to major industries and type of waste produced by them is also included. This book will appeal to students, researchers, scientists, industry persons and professionals in field of microbiology, biotechnology, environmental sciences, eco-toxicology, environmental remediation and waste management and other relevant areas, who aspire to work on the biodegradation and bioremediation of industrial wastes for environmental safety.

Given its scope, this book will appeal not only to researchers, teachers and students around the globe, but also to general readers.

Plastic is one of the widely used polymers around the globe since its discovery. It is highly impossible to think the ease of life without the aid of plastic. Every year billion tons of plastic waste gets accumulated in the environment and leads to death of both marine and terrestrial animals. Plastic is very durable and needs around 1000 years to degrade under the natural environment. The present book illustrates the importance and significance of the bioremediation to tackle the problem of plastic waste. Previously, we have reported elite rhizobacterial isolates (Lysinibacillus fusiformis strain VASB14/WL and Bacillus cereus strain VASB1/TS) of Avicennia marina Vierh (Forsk.) from the West Coast of India with the potential to degrade plastic (polythene). The present book attempted to address the bioremediation scenario of plastic waste (including micro plastic) using microbes with bacteria in particular. Various strategies used to tackle with the plastic waste were highlighted with case studies of plastic waste management, including in vitro, in situ and ex situ with a special reference to biodegradation technology. After the biodegradation of the plastic using microbes, the generated plastic (polythene) degradation products (PE-DPs) were also documented using GC-MS technique followed by their deleterious effect on both animal and plant systems. The book also enhances the awareness of the plastic-free society and also suggests some alternative materials to be used instead of plastic. Lastly, the book suggests/recommends the strategies to be followed by the lawmakers in the government organizations/non-government organizations/social organizations to frame the regulations and guidelines to implement at mass level to reduce the generation of plastic waste.

Emulsifiers, also known as surfactants, are often added to processed foods to improve stability, texture, or shelf life. These additives are regulated by national agencies, such as the FDA, or multi-national authorities, such as the EEC or WHO. The amphiphilic molecules function by assisting the dispersion of mutually insoluble phases and stabilizing the resulting colloids, emulsions, and foams. Emulsifiers can interact with other food components such as carbohydrates, proteins, water, and ions to produce complexes and mesophases. These interactions may enhance or disrupt structures and affect functional properties of finished foods. In dairy processing, small molecule emulsifiers may displace dairy proteins from oil/water and air/water interfaces, which affects stability and properties of the foams and emulsions. In baked products, emulsifiers contribute to secondary functionalities, such as dough strengthening and anti-staling. Synthetic food emulsifiers suffer from the stigma of chemical names on a product's ingredient statement. Modern consumers are seeking products that are "all natural." Fortunately, there are a number of natural ingredients that are surface-active, such as lecithin, milk proteins, and some protein-containing hydrocolloids. Mayonnaise, for example, is stabilized by egg yolk. This book can serve as both a guide for professionals in the food industry to provide an understanding of emulsifier functionality, and a stimulus for further innovation. Students of food science will find this to be a valuable resource.
