Molecular Wine Microbiology features rigorous scientific content written at a level comprehensible for wine professionals as well as advanced students. It includes information on production and spoilage issues, the microbial groups relevant for wine production and microbial wine safety. Microbiology has long been recognized as a key tool in studying wine production, however only recently have wine microbiology studies been addressed at a molecular level, increasing the understanding of how microbiology impacts not only the flavor quality of the wine, but also its safety. Understanding, at a molecular level, how a starter culture can impact ethanol, glycerol, volatile phenols, mannoproteins, biogenic amines or ochratoxin A of a wine are just some of the core points that must be considered in order to achieve maximium consumer acceptability while addressing safety concerns during processing and storage. While other books offer insights into the technological aspects of enology, this book is written by expert microbiologists, who explore the positive and negative impacts of gene function in the production of wine, from a microbiological point of view. Winner of the 2012 Jury Award in Enology from the International Organisation of Vine and Wine Presents the most current methods of studying the microbiology of wine Includes latest identification and typing methods, reducing identification time from days and weeks to minutes and hours Provides important knowledge about the impact of microbiological factors at the molecular level for reduction of wine spoilage and increased wine quality and safety

For centuries the transformation of grapes into wine has been the focus of much scientific research but it was not until the nineteenth century that the role of yeasts in alcoholic fermentation was discovered. Since this discovery the findings of chemists, biochemists and microbiologists have led to controlled conditions in winemaking, producing more varied and higher quality wines. Handbook of Enology Volume 1: The Microbiology of Wine and Vinifications uniquely combines scientific knowledge with the description of day-to-day work in the first stages of winemaking, from grape-picking to the end of the fermentation processes. It discusses the scientific basics and technological problems of wine-making and the resulting consequences for the practitioner, providing an authoritative and complete reference manual for both the winemaker and the student. This text will be invaluable to winemakers, students of enology or vinification and chemists interested in winemaking.

The "Microbiology" volume of the new revised and updated Handbook of Enology focuses on the vinification process. It describes how yeasts work and how they can be influenced to achieve better results. It continues to look at the metabolism of lactic acid bacterias and of acetic acid bacterias, and again, how can they be treated to avoid disasters in the winemaking process and how to achieve optimal results. The last chapters in the book deal with the use of sulfur-dioxide, the grape and its maturation process, harvest and pre-fermentation treatment, and the basis of red, white and speciality wine making. The result is the ultimate text and reference on the science and technology of the vinification process: understanding and dealing with yeasts and bacterias involved in the transformation from grape to wine. A must for all serious students and practitioners involved in winemaking.

Wine yeast and bacteria have been extensively characterized in terms of physiological and metabolic traits largely in pure culture analyses. Winemaking practices derived from this basic knowledge have undoubtedly improved wine quality. Phylogenetic studies and genome comparisons in extensive collections have revealed the processes of evolution and adaptation of the two main microbial species, Saccharomyces cerevisiae and Oenococcus oeni, present in wine. However, grapes and grape juice contain a variety of microorganisms and these principal agents of fermentation are in fact part of a complex microbial community that evolves dynamically in a special niche. Thanks to the new methods of analysis, the complexity of the microbiota can be measured in any sample of must or wine. In addition, there is greater appreciation of diversity within the main species present in wine. Intraspecific diversity has been evaluated in yeast and bacteria species and strains can be typed even in the mixture of selected or indigenous strains. Descriptions of microbial profiles in all the regions of the world suggest that the microbiota is a significant element of terroir or regional signature. It is no longer enough to simply describe what is present. It is important to consider evolution, physiology and metabolism taking into account microbial interactions within the community. Research in wine microbiology has also expanded our understanding of the participation and role of non-Saccharomyces organisms in winemaking, and refined knowledge on microbial spoilage. However, it is challenging to go from the simple description of these phenomena to their interpretation. The greatest difficulty lies in analyzing the functioning of the extraordinary complex system of yeast and bacteria present during different stages of the fermentation. Interactions in the very particular environment of fermenting grape induce alternations of relative populations’ dominances and declines with subsequent impacts on wine composition. Some mechanisms have been identified or suggested, but much remains to be done. The recent advent of inoculation with non-Saccharomyces in oenological practice, sometimes leading to inconstant results, reflects the profound gaps that exist in knowledge of the complexity of fermentation and wine microbial ecosystems. Understanding how the microbial community works is expected to provide a sound basis before using fermentation helpers and starters, taking into account the indigenous microbiota. It will also aid in monitoring and understanding native or uninoculated fermentations that rely on the complex interactions of grape, winery and fermentation biota for their aroma and flavor profile. The aim of this Research Topic was to bring together current knowledge on several key aspects of wine microorganism biology: i) Evolution / co-evolution of yeasts and bacteria in their process of domestication and adaptation to the oenological niche. ii) Mechanisms of interactions between species and strains, both on grapes and in grape must. iii) Metabolism and physiology of yeast and bacteria in interactions with each other and with the environment, considering to what extent expected objectives (typicity, lower alcohol, etc.,) can be reached by using selected strains. iv) Development of novel technologies or approaches for the assessment of changes in a dynamic microbial community and the linking of such changes to wine flavor and aroma properties. v) Diversity, ecology, physiology and metabolism of B. bruxellensis. Damage from this spoilage agent is not effectively prevented because we do not fully understand the biology of this species, particularly in interaction with other yeast and bacteria. Each chapter presents advances in these areas of study. Research in wine microbiology, particularly in the wine microbiome and its impacts on wine composition is enhancing our understanding of the complexities and dynamics of microbial food and beverage ecosystems.

Much has happened in the brewing industry since the last edition of this book was published in 1996. In particular, there has been substantial con solidation of larger brewing companies as major multinational concerns, and at the other end of the spectrum the microbrewing scene in various parts of the world has become established as a sustainable enterprise. For those involved in the scientific and technical aspects of fermented bever age production the changes have been no less daunting. The complete genome sequence of Saccharomyces cerevisiae has been determined and studies are underway in numerous laboratories throughout the world to unravel the expression of the genome (transcriptomics and proteomics) and understand exactly "how a yeast works. " This will undoubtedly con tribute to our understanding of yeast fermentation and flavor generation in a revolutionary way because it will enable the simultaneous monitor ing of all genes in the organism during the fermentation. In Chapters 2 and 3 of this volume Colin Slaughter and John Hammond bring the reader up-to-date in this rapidly moving area and cover the remarkable achievements of modern biochemistry and molecular biology. lain Campbell has also revised the systematics of culture and wild yeasts in Chapter 7. The other major technical change since the last edition of this book is the introduction of molecular characterization and detection of microor ganisms based largely, but not exclusively, on the polymerase chain reac tion (PCR) for amplification of specific DNA fragments.

Understanding the relationship between a microorganism and its environment is essential to the successful manipulation of industrial, biochemical, and medical processes. In Environmental Microbiology: Methods and Protocols, highly practiced experimentalists who often have perfected the methods they write about describe readily reproducible techniques for determining most of the important factors governing microorganisms and their habitats. Presented in step-by-step detail, these cutting-edge methods range from those for the study of marine organisms, to those for investigating microorganisms occurring in groundwater, to the biodiversity found in remote environments. The protocols for studying fermented milks are significant for investigators concerned with milk as an item of food for infants, small children, and even adults. Additional methods for the recovery and determination of nucleic acids and other compounds affecting, and affected by, microorganisms, are provided for certain enzymes produced by plant pathogens and for obtaining microbial species tolerant of such inhibitors as heavy metals. Review articles discuss the endophytic bacterium Bacillus mojavensis, the engineering of bacteria to enhance their ability to carry out bioremediation of aromatic compounds, and the use of chemical shift reagents and Na-NMR to study sodium gradients in microorganisms. The protocols follow the successful Methods in Molecular BiologyTM series format, each one offering step-by-step laboratory instructions, an introduction outlining the principle behind the technique, lists of equipment and reagents, and tips on troubleshooting and avoiding known pitfalls. State-of-the-art and highly practical, Environmental Microbiology: Methods and Protocols offers microbiological researchers a powerful set of techniques for investigating and understanding microorganisms in their native environments.

The pace of progress in fermentation microbiology and biotechnology is fast and furious, with new applications being implemented that are resulting in a spectrum of new products, from renewable energy to solvents and pharmaceuticals Fermentation Microbiology and Biotechnology, Second Edition builds on the foundation of the original seminal work, extending its reach to reflect the multidisciplinary and expansive nature of fermentation research and advancements. While retaining valuable information from the previous edition including a brief history of the industry, as well as an overview of instrumentation and fermentor design, fermentation kinetics, and flux control analysis, the second edition addresses numerous topics that have risen to prominence in the past few years. New chapters explore the diverse array of microbial biosynthetic pathways currently used by the fermentation and pharmaceutical industries for the production of primary and secondary metabolites such as amino acids, vitamins, antibiotics, immunosuppressants, and anti-tumor agents. The authors also examine recent advances in enzyme and co-factor engineering and cell immobilization with respect to both novel drug development and improved yields from microbial processes. Beyond pharmaceuticals, this volume considers the emerging role of fermentation in the conversion of renewable resources to fine chemicals, as well as its potential use in converting lignocellulosic waste to ethanol. In addition, readers will also discover new chapters devoted to discussions of industrial issues such as modeling and sensor technology, as well as supervision and control in the fermentation process. The text is packed with examples and case studies from the industry, carefully chosen to illuminate and reinforce principles and methodology discussed in the chapters. Organized and written in a concise and lucid manner that requires only a general background in microbiology, this volume meets the needs

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.
