The Yeasts Yeast Technology

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.

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.

Basic research is here applied to solve practical problems and to bring the reader up-to-date on recent developments of most aspects of yeast-based industries. Main topics cover: the brewing and distilling industries, wine-making and the nature of winery yeasts, food yeasts, spoilage yeasts, non-saccharomyces yeasts, their substrates and products; the construction of improved industrial yeast strains by site-directed mutagenesis, production of heterologous proteins by genetically-engineered yeasts, and factors affecting yields of such proteins as well as the use of calorimetry in control systems for yeast fermentations. This sourcebook will prove useful to everybody involved in technical applications of yeasts.

V.3 - Yeast technology.

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
