The second edition of Microorganisms in Foods 6: Microbial Ecology of Food Commodities is intended for those primarily in applied aspects of food microbiology. For 17 commodity areas it describes the initial microbial flora and the prevalence of pathogens, the microbiological consequences of processing, typical spoilage patterns, episodes implicating those commodities with foodborne illness, and measures to control pathogens and limit spoilage. The control measures are presented in a standardized format in line with international developments in risk management. A comprehensive index has also been added. Microorganisms in Foods 5, 7, and the second edition of Microorganisms in Foods 6 are for anyone using microbiological testing and/or engaged in setting Microbiological Criteria, whether for the purpose of Governmental Food Inspection and Control or in Industry, and for those identifying the most effective use of microbiological testing in the food chain. The contents are essential reading for food processors, food microbiologists, food technologists, veterinarians, public health workers and regulatory officials. For students in Food Science and Technology they offer a wealth of information on Food Microbiology and Food Safety Management, with many references for further study. The information has been prepared by the International Commission on Microbiological Specifications for Foods (ICMSF). The ICMSF was formed in response to the need for internationally acceptable and authoritative decisions on microbiological limits for foods moving in international commerce. Currently the membership consists of eighteen food microbiologists from eleven countries, drawn from governmental laboratories in public health, agriculture, and food technology, from universities and from the food industry.

The rhizosphere in soil environments refers to the narrow zone of soil influenced by the root and exudates. Microbial populations in the rhizosphere can be 10 - 100 times larger than the populations in the bulk soil. Therefore, the rhizosphere is bathed in root exudates and microbial metabolites and the chemistry and biology at the soil-root interface is governed by biotic (plant roots, microbes) and abiotic (physical and chemical) interactions. The research on biotic and abiotic interactions in the rhizosphere should, thus, be an issue of intense interest for years to come. This bo

As a result of various human activities, such as increase in human population, decrease in arable land due to soil degradation, urbanization, industrialization and associated increase in the demand for livestock products, dramatic changes are occurring in the global ruminant livestock sector. These changes include shift in the size of regional livestock populations and in the types of management and feeding systems under which ruminant livestock are held, and increased demand of a wider range of quality attributes from animal agriculture, not just of the products themselves but also of the methods used in their production. The livestock sector will need to respond to newchallengesofincreasinglivestockproductivitywhileprotectingenvironmentand human health and conserving biodiversity and natural resources. The micro-organisms in the digestive tracts of ruminant livestock have a profound influence on the conversion of feed into end products, which can impact on the imal and the environment. As the livestock sector grows particularly in developing countries, there will be an increasing need to understand these processes for better management and use of both feed and other natural resources that under pin the development of sustainable feeding systems.

Microbial Diversity offers the first comprehensive, in-depth treatment of microbial diversity for undergraduate and graduate students. Using a global approach, it illustrates the impact of microorganisms on ecological and earth system phenomena. Beginning with a detailed treatment of key concepts and methods, including the nature of microbial species, and the use of microscopic, culture, molecular and phylogenetic systematic methods, it then focuses on environmental evolution, biochemical cycling and species interactions. The text's extensive art program, including its 4-color images of microbes, will be available to instructors on CD-ROM, as well as on the web. The website will also feature an interactive microbe area. Combining molecular, genetic and microbial diversity, this textbook presents recent advances in this growing field and connects diversity with ecology and evolution. Microbial Diversity will be a vital resource, as well as an essential text for classroom use.

Decomposition of organic matter is a major ecosystem process involving an array of different organisms, including bacteria, fungi and invertebrates. The main objective of this book is to provide students and laboratory instructors at universities and professional ecologists with a broad range of established methods to study plant litter decomposition. Detailed protocols for direct use in the field or laboratory are presented in an easy to follow step-by-step format. A short introduction to each protocol reviews the ecological significance and principles of the technique and points to key references. Although most methods are described for freshwater ecosystems, many will work equally well in the presented or slightly modified form for studies in marine and terrestrial environments.

The ?rst 30 cm of the earth’s surface represents a fragile and valuable ecos- tem, thanks to which terrestrial plants, and indirectly animals and humans, can live. The microbial activity occurring in soil is largely responsible for its physical and nutritional quality. Among the micro-organisms living in soil, the arbuscular mycorrhizal (AM) fungi play a major role. They are present in all types of soil, everywhere on the planet, living in symbiotic association with the roots of most plant species. They have co-evolved with plants for 400 million years, improving their nutrition and resistance to v- ious types of stress. Present practices in conventional agriculture, which introduce great amounts of chemicals, have eliminated or underexploited the AM symbiosis. The rational exploitation of AM fungi in sustainable agriculture, to help minimize the use of chemical fertilizers and pesticides, has been hampered by several biological characteristics of these mic- organisms: they cannot be grown in the absence of a plant host and their genetic structure is very complex. Despite these limitations, biologists have made important progress in understanding better the functioning of AM fungi. An in vitro technique has been developed using mycorrhizal root organ cultures, which made it possible to investigate the genetics, cell biology and physiology of AM fungi. We can now be objective enough to critically evaluate the impacts the in vitro technique has had to improve our knowledge on mycorrhizal symbiosis.

The importance of combating infectious diseases has received international attention, providing the opportunity for a multidisciplinary approach that combines medicine with other scientific and technological capabilities, notably information technology, nanotechnology, and biotechnology. In fact, it has been predicted that the future will bring a merging of these technologies with the cognitive and behavioral sciences—major forces that have the potential to balance the world’s inequities. The scientific community and world leaders must work together to use knowledge and its applications to improve the condition of the planet. The connection between infectious diseases and the oceans provides a paradigm for this perspective. A stark global context indisputably frames all human health issues in the twenty-first century: the world wide movement of people and goods. Throughout the past half century, international travel has skyrocketed; there are more than 500 million international arrivals per year. The greatest increase has taken place since the mid-1990s. The world has become integrated and global; consequently, the notion that it is possible to successfully eradicate a disease from the face of the planet has become simplistic. Infectious disease is a moving target and climate shifts will affect any disease that has an environmentally sensitive stage or vector. Recognizing signals from climate models and incorporating them into health measures can provide new opportunities for proactive—rather than reactive—approaches to public health. Thus, careful attention to the role of the oceans in human health can offer new avenues of research that will provide new means of predicting and preventing those diseases that are rooted in the environment. In this volume, pathogens in the sea are reviewed by Colin Munn, who provides a broader perspective for the topic of pathogenic microorganisms associated with the world oceans.
