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 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.

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.

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.

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.

This book gives a general overview of the biology and molecular biology of yeasts. Topics emphasized include yeast taxonomy (including evolution of yeasts), yeast ecology, with as much emphasis as possible on the relationship between the organisms and the environment, the structure and function of the yeast cell, its life cycle and metabolism, and the relationship between yeasts and mankind, including pathogenicity, traditional and current industrial and therapeutic uses and related topics. The contribution of yeasts to fundamental research in biology is discussed as an integral part of the subject.

It is well established that certain strains of yeasts are suitable for transforming grape sugars into alcohol, while other yeast strains are not suitable for grape fermentations. Recent progress has clearly demonstrated that the sensory profile of a wine is characteristic of each vine cultivated, and the quality and technological characteristics of the final product varies considerably due to the strains which have performed and/or dominated the fermentation process. Because of their technological properties, wine yeast strains differ significantly in their fermentation performance and in their contribution to the final bouquet and quality of wine, such as useful enzymatic activities and production of secondary compounds related both to wine organoleptic quality and human health. The wine industry is greatly interested in wine yeast strains with a range of specialized properties, but as the expression of these properties differs with the type and style of wine to be made, the actual trend is in the use of selected strains, which are more appropriate to optimize grape quality. Additionally, wine quality can be influenced by the potential growth and activity of undesirable yeast species, considered spoilage yeasts, which cause sluggish and stuck fermentation and detrimental taste and aroma in the wine.
