    Cation Flux Across Biomembranes documents the proceedings of a symposium on ""Cation Flux across Biomembranes"" sponsored by the Japan Bioenergetics Group, held September 10-13, 1978 at the Inter-University Seminar House of Kansai in Kobe, Japan. The symposium brought together 80 of the leading investigators concerned with ATP-utilizing and ATP-generating systems associated with cation fluxes across membranes to discuss biochemical mechanisms in depth and their relation to cation transport functions. The papers presented focused on three types of membrane systems. The first two membrane systems are classified as ATP-utilizing systems. These include the plasma membrane, associated with the ATP dependent Na+-K+ transport system, which draws upon most of the cell's energy for cation fluxes; and the sarcoplasmic recticulum membrane associated with Ca++ transport, which plays a key role in excitation-contracti... coupling in muscle. The third type of membrane system falls under ATP-generating systems. These include the inner membranes of mitochondria, chloroplasts, and bacteria associated with H+ fluxes generated by oxidation-reduction reactions, and their coupling to secondary ion flows and oxidative and photosynthetic phosphorylation. H+ transport associated with the photoreaction cycle of bacteriorhodopsin, the light energy converted in halobacteria was also considered.

    Inhibition and Destruction of the Microbial Cell focuses on the effects of various classes of toxic chemical agents on microbial cell. This book is organized into 14 chapters that cover the topics from two points of view: the agent and the target (the microbial cell). The introductory chapters are devoted to the inhibitory effects of elevating temperature and to the lethal effect of environmental thermal energy supply restriction on growing bacteria. A chapter focuses on the effect of various classes of antibacterial compounds, such as 4-amino-quinaldinium and 8-hydroxyquinoline derivatives, chlorhexidine, amidines, halogens, dyes, and nitrofurans. The subsequent chapters examine the effects of other chemical agents on microorganisms, including toxic gases, solutes, ions, and radiations. The book goes on examining the inhibition and destruction of specific microorganisms, such as Pseudomonas aeruginosa, Enterobacteriaceae, Mycobacteria, Cocci, bacterial spores, molds, yeasts, and viruses. The last chapter discusses the effect of the cultural prehistory of microorganisms upon their response to inhibition and destruction. This book is an invaluable resource for graduate research workers and scientists in pure and applied microbiology. This will also be a good reference for undergraduates reading specialized courses at honors level in microbiology or applied courses in food science and agriculture.

    Environmental and consumer activists have for a long time blamed pesticides, fertilizers and other aspects of intensive farming for causing environmental degradation and human disease. Yet, as the authors in this book show, intensive farming has enabled growth in food production at a rate greater than population growth, thereby ensuring that people are better fed than ever before, whilst simultaneously limiting the effect of farming on the environment.The authors debunk numerous pervasive myths, including:Myth: Pesticides are bad for the environment and bad for human healthFact: Synthetic pesticides enable the production of large quantities of fresh fruit and vegetables, which means that people are better protected against cancer. In addition, the synthetic pesticides themselves are often less toxic than natural pesticides. Overall, synthetic pesticides present a net gain in health terms.Myth: Antibiotic resistance in animals is spreading to humans.Fact: The use of antibiotics in young animals keeps meat prices low and does not materially contribute to antibiotic resistance in humans.Myth: Nitrate fertilizers are a threat to human health.Fact: Nitrate fertilizers are probably beneficial to human health.Myth: Genetically modified organisms (GMOs) are bad for the environment and bad for our health.Fact: Many environmental problems associated with agriculture can be reduced by using GMOs, which have the potential to improve yields and quality which simultaneously reducing associated inputs, such as fertilizers, herbicides and pesticides. Commercially produced GM foodcrops have no known impacts on human health and future GM foodcrops are likely to have health benefits (enabling such things as low-fat chips/french fries and non-allergenic peanuts).Myth: Instances of food poisoning would be reduced if we had more regulations.Fact: Instances of food poisoning in the UK may have been exacerbated by over-cautious government regulation.Myth: Subsidies are needed to order to ensure that food and fish are produced in environmentally sound ways.Fact: Subsidies to fisheries and farming have caused widespread environmental degradation.Myth: Packaging and transporting food is environmentally unfriendly.Fact: Packaging enhances the shelf life of products and reduces wastage during transport. Transporting food allows society to take advantage of different environmental and socio-economic conditions that exist in different places.

    • Inglés
    Warmed-Over Flavor of Meat discusses related problems and issues on warmed-over flavor (WOF) of meat that contributes to a decrease in sale, meat consumption, and production expansion. WOF is old, stale, rancid, and painty flavor and odor of meat, apparently caused by the catalytic oxidation of unsaturated fatty acids. Comprised of 10 chapters, the book initially describes the mechanisms of metals’ role in the promotion of lipid oxidation. The text also discusses the content and distribution of iron in meat and the evidence concerning the ability of the various forms of iron in meat to promote oxidative degradation of lipids. The subsequent chapters describe the oxidative deterioration in muscle foods and the free radical processes pertinent to autoxidation of foods. A chapter presents evidence for and against heme catalysis of lipid oxidation and the antioxidant role of nitrite in cured meats. The book also considers sensory and instrumental analysis of volatiles and undesirable flavors related to WOF and the isolation and separation of heteroatomic compounds associated with beef flavor. The remaining chapters describe several methodologies for retarding or preventing WOF in meat, focusing on the practical procedure of the Maillard reaction. Lastly, sources of natural antioxidants for meat product preservation are considered. Food scientists, researchers, and manufacturers will find this book invaluable.
