The Yeasts

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

This classic series covers the complete biology and biochemistry of the yeasts in six volumes. Volume 5 addresses the major areas of yeast technology relevant to the food, pharmaceutical, and biotechnology industries. * SPECIAL FEATURES: * Final volume of a comprehensive research level edited treatise covering biochemistry physiology, technology of yeasts. The book will cover the major areas of yeast technology relevant to the food, pharmaceutical and biotechnology industries. Yeast are highly versatile organisms, particularly suitable for industrial purposes - this book will be of interest to many.

This impressive volume presents 60 genera and 500 species of yeasts. The aims of The Yeasts is two-pronged -first, presenting and discussing a classification of yeasts including diagnoses of genera and descriptions of species, and second, providing methods for the identification of yeast strains. Knowledge of the basidioporogenous yeasts has increases considerably in recent years. These yeasts are now classified in two taxonomically different groups, the teliospore-forming yeasts and the Filobasidiaceae. There are also other basidiomycetous fungi, such as the Tremellales, with a yeast phase in their life cycle. The descriptions of the yeast states of several of these species have been included in this edition. The taxonomic system proposed is a large step in the evolution of a satisfactory classification. More than 1000 pages of information from 16 contributors -well laid out and easy to consult, classified for easy access. The Fourth Revised Edition, edited by C.P. Kurtzman and J. Fell, is due for publication in 1998.

The yeasts are a phylogenetically diverse group of fungi characterized by unicellular growth. Yeasts have been used for bread making and brewing beverages for millennia, and have become increasingly important in biotechnology for production of fuel alcohol, organic acids, enzymes, and various pharmacologically important chemicals. Other species are serious human, animal, and plant pathogens. Since publication of the 3rd edition of this book in 1984, numerous new species and genera have been described, many because of the application of new molecular biological methods. Molecular comparisons have now provided a phylogenetic distinction between the yeasts and other fungi, some of which have a unicellular growth phase. This book is the most definitive treatment of taxonomy and systematics of yeasts available and has been prepared by an international team of experts and is directed at taxonomists, ecologists, mycologists, microbiologists, clinicians, molecular geneticists, and biotechnologists.

As a group of microorganisms, yeasts have an enormous impact on food and bev- age production. Scientific and technological understanding of their roles in this p- duction began to emerge in the mid-1800s, starting with the pioneering studies of Pasteur in France and Hansen in Denmark on the microbiology of beer and wine fermentations. Since that time, researchers throughout the world have been engaged in a fascinating journey of discovery and development – learning about the great diversity of food and beverage commodities that are produced or impacted by yeast activity, about the diversity of yeast species associated with these activities, and about the diversity of biochemical, physiological and molecular mechanisms that underpin the many roles of yeasts in food and beverage production. Many excellent books have now been published on yeasts in food and beverage production, and it is reasonable to ask the question – why another book? There are two different approaches to describe and understand the role of yeasts in food and beverage production. One approach is to focus on the commodity and the technology of its processing (e. g. wine fermentation, fermentation of bakery products), and this is the direction that most books on food and beverage yeasts have taken, to date. A second approach is to focus on the yeasts, themselves, and their bi- ogy in the context of food and beverage habitats.

A Guide to the World of the Yeasts J. F. T. Spencer and D. M. Spencert As the well-known authority on yeasts, the late Professor Rose, frequently pointed out, it is impossible for one person to present, in a single volume, the details of the life, composiotion, habitats, relationships, and actual and potential uses to man kind of the 500 (at last count) known species of yeasts. This book confirms the truth of this statement. However, our aim is actually more modest than that, and this book is an attempt to introduce the general reader, and possibly some inter ested specialists, to the lives of the yeasts in their natural and more artificial habitats, their use by human beings, and to give some idea of the wonderfully complex activities within the yeast cell, the characteristics of the metabolism and molecular biology of yeasts, and the applications of these characteristics to life in the present-dayworld ofhuman existence. The book proceeds from a brief chapter on what is and is not known of the origins and early history of the yeasts, through a description of their classification, relationships, habitats and general life style, their external morphology and internal structures and mechanisms within their cells, the regulatory mechanisms controlling processes such as signal transmis sion, mating, cell fusion, and many others.

Mycological studies of yeasts are entering a new phase, with the sequencing of multiple fungal genomes informing our understanding of their ability to cause disease and interact with the host. At the same time, the ongoing use of traditional methods in many clinical mycology laboratories continues to provide information for the diagnosis and treatment of patients. This volume reviews various aspects of pathogenic yeasts and what is known about their molecular and cellular biology and virulence, in addition to looking at clinical and laboratory findings. As each chapter is written by a leading expert in the field, this book summarizes in one volume much of the latest research on several pathogenic yeasts, including Candida, Cryptococcus, Malassezia and yeasts of emerging importance. The importance of laboratory diagnosis, antifungal susceptibility testing, antifungal resistance and yeast diseases in animals are reviewed.

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
