The purpose ofthis brief Foreword is to make you, the reader, hungry for the scientific feast that follows. These two volumes on the prokary otes offer a truly unique scientific menu-a comprehensive assembly of articles, exhibiting the biochemical depth and remarkable physiological and morphological diversity of prokaryote life. The size of the volumes might initially discourage the unprepared mind from being attracted to the study of prokaryote life, for this landmark assemblage thoroughly documents the wealth of present knowledge. But in confronting the reader with the state of the art, the Handbook also defines where new work needs to be done on well-studied bacteria as well as on unusual or poorly studied organisms. There are basically two ways of doing research with microbes. A classical approach is first to define the phenomenon to be studied and then to select the organism accordingly. Another way is to choose a specific organism and go where it leads. The pursuit of an unusual microbe brings out the latent hunter in all of us. The intellectual chal lenges of the chase frequently test our ingenuity to the limit. Sometimes the quarry repeatedly escapes, but the final capture is indeed a wonder ful experience. For many of us, these simple rewards are sufficiently gratifying so that we have chosen to spend our scientific lives studying these unusual creatures.

Microbiology of Foods 6: Microbial Ecology of Food Commodities was written by the ICMSF, compris ing 19 scientists from II countries, plus 12 consultants and 12 chapter contributors. This book brings up to date Microbial Ecology of Foods, Volume 2: Food Commodities (1980, Academic Press), taking account of developments in food processing and packaging, new ranges of products, and foodborne pathogens that have emerged since 1980. The overall structure of each of the chapters has been retained, viz. they cover: (i) the important properties of the food commodity that affect its microbial content; (ii) the initial microbial flora at slaughter or harvest; (iii) the effect of harvesting, transportation, processing and storage on the microbial content; and (iv) the means of controlling processes and the microbial content. The section on Choice of Case has not been included in this 2nd edition, reflecting the changed emphasis in ensuring the microbi ological safety of foods. At the time of publication of Microbial Ecology of Foods, Volume 2: Food Commodities, control of food safety was largely by inspection and compliance with hygiene regulations, coupled with end-product testing. Such testing was put on a sound statistical basis through sampling plans introduced in Microorganisms in Foods 2: Sampling for Microbiological Analysis: Principles and Specific Applications (2nd edition 1986, University of Toronto Press).

Hypersaline environments are the principal habitats of petroleum deposition. They are also of intense evolutionary and ecological interest. This book presents a cross-disciplinary examination of the variety of halophilic microorganisms and their roles in modifying the ecology and geochemistry of hypersaline environments. The book also covers in detail the various inland and coastal habitats where halophilic microorganisms thrive. Geographically, hypersaline environments extend from the tropics to the poles, and from the terrestrial to the submarine. Organisms capable of living in such environments have faced unique evolutionary challenges.

Concern over the depletion of world energy resources and the increase in the cost of nitrogen fertilizer has prompted considerable interest and research in biological nitrogen fixation. This volume discusses the most recent advances in the field, with chapters written by experts on the ecology, physiology, biochemistry and genetics of biological nitrogen fixation. Grain legumes, rice, sugar cane, sorghum and millet are all covered in the book. Some of the chapters particularly focus on the genetics and molecular biology of nitrogen fixing bacteria, and summarize the biotechnological strategies that are being applied in the hope of rendering plants self-sufficient with regard to nitrogen fertilization.

Advances in Aquatic Microbiology Volume 1 describes the characteristics of ecological niches for individual microorganisms and the intensities of individual microbiological processes in the course of turnover of various substances in reservoirs. This volume follows Volume 1 of Advances in Microbiology of the Sea book. The opening chapter presents insight to the tradition of Russian limnological microbiology followed by a discussion on conversion of inorganic nitrogen to organic nitrogen, and the microorganisms responsible for assimilatory reactions. The book considers aspects of the reduction of atmospheric dinitrogen and nitrate to ammonia and the incorporation of ammonia into organic compounds. Such considerations will relate particularly to those organisms of significance in aquatic environments. The relations between prey and predator and their significance in the investigation both the behavior of the microorganisms themselves and the prey-predator situation in general are also discussed. Chapter 4 examines how viruses, bacteria, and fungi affect the blue-green algae and the development and regulation of algal blooms. The final two chapters summarize studies in freshwater sediment microbiology and the role of bacteria in water pollution monitoring. This book caters primarily to aquatic microbiologists, but limnological microbiologists, aquatic researchers, scientists, teachers, and students with courses in aquatic microbiology will find this book invaluable.
