Book Description
The contamination of the environment by herbicides, pesticides, solvents, various industrial byproducts (including toxic metals, radionucleotides and metalloids) is of enormous economic and environmental significance. Biotechnology can be used to develop "green" or environmentally friendly solutions to these problems by harnessing the ability of bacteria to adapt metabolic pathways, or recruit new genes to metabolise harmful compounds into harmless byproducts. In addition to its role in cleaning-up the environment, biotechnology can be used for the production of novel compounds with both agricultural and industrial applications. Internationally acclaimed authors from diverse fields present comprehensive reviews of all aspects of Industrial and Environmental Biotechnology. Chapters concerned with environmental biotechnology cover two major categories of pollutants: organic compounds and metals. Organic pollutants include cyclic aromatic compounds, with/without nitrogenous or chloride substitutions while metal pollutants include copper, chromate, silver, arsenic and mercury. The genetic basis of bioremediation and the microbial processes involved are examined, and the current and/or potential applications of bioremediation are discussed. The use of biotechnology for industrial and agricultural applications includes a chapter on the use of enzymes as biocatalysts to synthesize novel opiate derivatives of medical value. The conversion of low-value molasses to higher value products by biotechnological methods and the use tissue culture methods to improve sugar cane and potatoes crop production is discussed.

Book Description
Identifying pathogens in food quickly and accurately is one of the most important requirements in food processing. The ideal detection method needs to combine such qualities as sensitivity, specificity, speed and suitability for on-line applications. Detecting pathogens in food brings together a distinguished international team of contributors to review the latest techniques in microbiological analysis and how they can best be used to ensure food safety.Part one looks at general issues, beginning with a review of the role of microbiological analysis in food safety management. There are also chapters on the critical issues of what to sample and how samples should be prepared to make analysis effective, as well as how to validate individual detection techniques and assure the quality of analytical laboratories. Part two discusses the range of detection techniques now available, beginning with traditional culture methods. There are chapters on electrical methods, ATP bioluminescence, microscopy techniques and the wide range of immunological methods such as ELISAs. Two chapters look at the exciting developments in genetic techniques, the use of biosensors and applied systematics.Detecting pathogens in food is a standard reference for all those concerned in ensuring the safety of food. - Reviews the latest techniques in microbiological analysis and how they can best be used to ensure food safety - Examines the role of microbiological analysis in food safety management and discusses the range of detection techniques available - Includes chapters on electrical methods, ATP bioluminescence, microscopy techniques and immunological methods such as ELISAs

Book Description
Recent and forecasted advances in microbiology, molecular biology, and analytical chemistry have made it timely to reassess the current paradigm of relying predominantly or exclusively on traditional bacterial indicators for all types of waterborne pathogens. Nonetheless, indicator approaches will still be required for the foreseeable future because it is not practical or feasible to monitor for the complete spectrum of microorganisms that may occur in water, and many known pathogens are difficult to detect directly and reliably in water samples. This comprehensive report recommends the development and use of a "tool box" approach by the U.S Environmental Protection Agency and others for assessing microbial water quality in which available indicator organisms (and/or pathogens in some cases) and detection method(s) are matched to the requirements of a particular application. The report further recommends the use of a phased, three-level monitoring framework to support the selection of indicators and indicator approaches.Â

Book Description
Globalization of the food supply has created conditions favorable for the emergence, reemergence, and spread of food-borne pathogens-compounding the challenge of anticipating, detecting, and effectively responding to food-borne threats to health. In the United States, food-borne agents affect 1 out of 6 individuals and cause approximately 48 million illnesses, 128,000 hospitalizations, and 3,000 deaths each year. This figure likely represents just the tip of the iceberg, because it fails to account for the broad array of food-borne illnesses or for their wide-ranging repercussions for consumers, government, and the food industry-both domestically and internationally. A One Health approach to food safety may hold the promise of harnessing and integrating the expertise and resources from across the spectrum of multiple health domains including the human and veterinary medical and plant pathology communities with those of the wildlife and aquatic health and ecology communities. The IOM's Forum on Microbial Threats hosted a public workshop on December 13 and 14, 2011 that examined issues critical to the protection of the nation's food supply. The workshop explored existing knowledge and unanswered questions on the nature and extent of food-borne threats to health. Participants discussed the globalization of the U.S. food supply and the burden of illness associated with foodborne threats to health; considered the spectrum of food-borne threats as well as illustrative case studies; reviewed existing research, policies, and practices to prevent and mitigate foodborne threats; and, identified opportunities to reduce future threats to the nation's food supply through the use of a "One Health" approach to food safety. Improving Food Safety Through a One Health Approach: Workshop Summary covers the events of the workshop and explains the recommendations for future related workshops.

Book Description
Rapid multiplex detection of pathogens in the environment and in our food is a key factor for the prevention and effective treatment of infectious diseases. Biosensing technologies combining the high selectivity of biomolecular recognition and the sensitivity of modern signal detection platforms are a prospective option for automated analyses. They allow rapid detection of single molecules as well as cellular substances. This book, including 12 chapters from 50 authors, introduces the principles of identification of specific pathogen biomarkers along with different biosensor-based technologies applied for pathogen detection.

Book Description
The genus Salmonella comprises an important number of bacterial species able to colonize and infect numerous animal species and humans. Although more than a hundred years passed since its discovery, Salmonella still represents a redoubtable and successful microorganism, difficult to deal with. Whether we discuss about typhoid fever or food poisoning, the public health and financial consequences are practically incalculable. The costs attributable to Salmonella contamination of meat, eggs, and vegetables are also very high worldwide. Antimicrobial resistance in Salmonella isolates is an emerging threat not only in humans, and special measures should be addressed to this global problem. The book Current Topics in Salmonella and Salmonellosis contains a series of reviews about all-important issues concerning these subjects. It comprises 14 chapters grouped in 4 sections emphasizing new insights into pathogenesis, bacterial detection and antibiotic resistance, infections in animals, risk factors, and control strategies. The new genomic data and the exhaustive presentation of molecular pathogenesis bring novelty to the book and can help to improve our knowledge about Salmonella-induced diseases.

Book Description
Developments such as the increasing globalization of the food industry, constant innovations in technologies and products, and changes in the susceptibility of populations to disease have all highlighted the problem of emerging pathogens, either newly discovered through more sensitive analytical methods, linked for the first time to disease in humans, or newly associated with a particular food. Designed for microbiologists and quality assurance professionals and for government and academic food safety scientists, this timely reference discusses ways of identifying emerging pathogens and includes chapters on individual pathogens, their epidemiology, methods of detection, and means of control.
