Book Description
Yeasts are the active agents responsible for three of our most important foods - bread, wine, and beer - and for the almost universally used mind/ personality-altering drug, ethanol. Anthropologists have suggested that it was the production of ethanol that motivated primitive people to settle down and become farmers. The Earth is thought to be about 4. 5 billion years old. Fossil microorganisms have been found in Earth rock 3. 3 to 3. 5 billion years old. Microbes have been on Earth for that length of time carrying out their principal task of recycling organic matter as they still do today. Yeasts have most likely been on Earth for at least 2 billion years before humans arrived, and they playa key role in the conversion of sugars to alcohol and carbon dioxide. Early humans had no concept of either microorganisms or fermentation, yet the earliest historical records indicate that by 6000 B. C. they knew how to make bread, beer, and wine. Earliest humans were foragers who col lected and ate leaves, tubers, fruits, berries, nuts, and cereal seeds most of the day much as apes do today in the wild. Crushed fruits readily undergo natural fermentation by indigenous yeasts, and moist seeds germinate and develop amylases that produce fermentable sugars. Honey, the first con centrated sweet known to humans, also spontaneously ferments to alcohol if it is by chance diluted with rainwater. Thus, yeasts and other microbes have had a long history of 2 to 3.

Book Description
The Yeasts: A Taxonomic Study is a three-volume book that covers the taxonomic aspect of yeasts. The main goal of this book is to provide important information about the identification of yeasts. It also discusses the growth tests that can be used to identify different species of yeasts, and it examines how the more important species of yeasts provide information for the selection of species needed for biotechnology. • Volume 1 discusses the identification, classification and importance of yeasts in the field of biotechnology. • Volume 2 focuses on the identification and classification of ascomycetous yeasts. • Volume 3 deals with the identification and classification of basidiomycetous yeasts, along with the genus Prototheca. - High-quality photomicrographs and line drawings - Detailed phylogenetic trees - Up-to-date, clearly presented yeast taxonomy and systematic, easy-to-use reference sequence accession numbers to allow for correct identification

Book Description
Yeasts play a key role in the production of many foods and beverages. This role now extends beyond their widely recognized contributions to the production of alcoholic beverages and bread to include the production of many food ingredients and additives, novel uses as probiotic and biocontrol agents, their significant role as spoilage organisms, and their potential impact on food safety. Drawing upon the expertise of leading yeast researchers, this book provides a comprehensive account of the ecology, physiology, biochemistry, molecular biology, and genomics of the diverse range of yeast species associated with the production of foods and beverages.

Book Description
The purpose of this and future volumes of the Handbook of Genetics is to bring together a collection of relatively short, authoritative essays or annotated compilations of data on topics of significance to geneticists. Many of the essays will deal with various aspects of the biology of certain species selected because they are favorite subjects for genetic investigation in nature or the laboratory. Often there will be an encyclopedic amount of information available on such a species, with new papers appearing daily. Most of these will be written for specialists in a jargon that is be wildering to a novice, and sometimes even to a veteran geneticist working with evolutionarily distant organisms. For such readers what is needed is a written introduction to the morphology, life cycle, reproductive be havior, and culture methods for the species in question. What are its par ticular advantages (and disadvantages) for genetic study, and what have we learned from it? Where are the classic papers, the key bibliographies, and how does one get stocks of wild type or mutant strains? The chapters devoted to different species will contain information of this sort. Only a few hundreds of the millions of species available to biologists have been subjected to detailed genetic study. However, those that have make up a very heterogeneous sample of the living world.

Book Description
Since some food additives have been shown to be harmful to certain individuals, a common perception now is that all food additives are potentially dangerous. This had led to a large market for products making minimal use of additives. Tight regulatory control and labelling requirements provide further impetus for the development of these products. This book provides an authoritative and comprehensive review of the industrially important advances in the technology that allow food products to be manufactured with fewer of the additives that have been traditionally used. Also, many new natural and harmless ingredients and additives are becoming available. These are also covered to enable new product concepts to be considered. The first edition of this book was widely accepted as a key reference in this subject, and this new edition has been thoroughly revised throughout to reflect current trends and practice. The chapters on packaging, marine-derived ingredients, animal-derived ingredients and reduced-additive breadmaking have all been extensively revised and additional authors and co-authors have been recruited for the second edition. Topics such as active packaging, good manufacturing practice, HACCP and natural ingredients have been reviewed with regards to their effect on the technology of reduced-additive foods.

Book Description
Yeasts play a crucial role in the sensory quality of a wide range of foods. They can also be a major cause of food spoilage. Maximising their benefits whilst minimising their detrimental effects requires a thorough understanding of their complex characteristics and how these can best be manipulated by food processors.Yeasts in food begins by describing the enormous range of yeasts together with methods for detection, identification and analysis. It then discusses spoilage yeasts, methods of control and stress responses to food preservation techniques. Against this background, the bulk of the book looks at the role of yeasts in particular types of food. There are chapters on dairy products, meat, fruit, bread, soft drinks, alcoholic beverages, soy products, chocolate and coffee. Each chapter describes the diversity of yeasts associated with each type of food, their beneficial and detrimental effects on food quality, methods of analysis and quality control.With its distinguished editors and international team of over 30 contributors, Yeasts in food is a standard reference for the food industry in maximising the contribution of yeasts to food quality. - Describes the enormous range of yeasts together with methods for detection, identification and analysis - Discusses spoilage yeasts, methods of control and stress responses to food preservation techniques - Examines the beneficial and detrimental effects of yeasts in particular types of food, including dairy products, meat, fruit, bread, soft drinks, alcoholic beverages, soy products, chocolate and coffee

Book Description
When I undertook the production of the First Edition of this book it was my first foray into the world of book editing, and I had no idea of what I was undertaking! I was not entirely alone in this, as in asking me to produce such a book the commissioning Editor, Mr George Olley of Elsevier Ap plied Science Publishers, had pictured a text of perhaps 300 pages, but on seeing my list of chapter titles realized that we were talking about a - chapter, two-volume work. We eventually decided to go ahead with it, and the result was more successful than either of us had dared to hope could be It was therefore with rather mixed emotions that I contemplated the case. a second edition at the suggestion of Blackie Press, who had taken over the title from Elsevier. On the one hand, I was naturally flattered that the book was considered important enough to justify a second edition. On the other hand, I was very well aware that the task would be even greater this time.
