In contrast to previous publications, this book consistently focuses on the biology of wine-associated microbes. An international board of expert wine researchers describes the relevant ecological, physiological and genetic aspects of wine microbiology.

The second edition of the book begins with the description of the diversity of wine-related microorganisms, followed by an outline of their primary and energy metabolism. Subsequently, important aspects of the secondary metabolism are dealt with, since these activities have an impact on wine quality and off-flavour formation. Then chapters about stimulating and inhibitory growth factors follow. This knowledge is helpful for the growth management of different microbial species. The next chapters focus on the application of the consolidated findings of molecular biology and regulation the functioning of regulatory cellular networks, leading to a better understanding of the phenotypic behaviour of the microbes in general and especially of the starter cultures as well as of stimulatory and inhibitory cell-cell interactions during wine making. In the last part of the book, a compilation of modern methods complete the understanding of microbial processes during the conversion of must towine.This broad range of topics about the biology of the microbes involved in the vinification process could be provided in one book only because of the input of many experts from different wine-growing countries.

Der "Fall Schwerte" hat internationales Aufsehen erregt: Im April 1995 erklarte der ehemalige Germanistik-Professor und Rektor der RWTH Aachen Hans Schwerte, dass er am Ende des Zweiten Weltkriegs seinen Namen gewechselt habe und im NS-Regime unter seinem ersten Namen Hans Ernst Schneider an fuhrender Stelle im "SS-Ahnenerbe" tatig gewesen sei. - Der Band stellt den Fall in mehrere Kontexte: a) den Kontext von Publizisten und Propagandisten im NS-Regime, b) den Kontext des Elitenwechsels in der fruhen Bundesrepublik, c) den Kontext der Geschichte der Germanistik, d) den Kontext von Berufungsvorgangen, e) den Kontext anderer belasteter Wissenschaftler nach 1945.

Soil microorganisms play a major role in the degradation and recycling of organic material. Microbes are involved in the food web and strongly contribute to soil fertility. In the past, attention was mainly directed towards free-living or particle-bound microorganisms, while the role of intestinal microbes of soil animals has been neglected.For the first time, "Intestinal Microorganisms of Termites and Other Invertebrates" focuses on the microbes in gut systems of soil animals. It starts with a profound overview of the biology of soil invertebrates. A major part deals with the gut microbiota of termites, the best investigated gut system of invertebrates. Termites are important soil processors in tropical and subtropical regions. Insight is given into the intestinal microbiota of further relevant primary litter decomposers, such as earthworms, springtails, millipeds, and woodlice. Novel techniques for studying intestinal microbes complete the volume.

Winemaking depends on a complex group of microorganisms such as yeasts, bacteria, and fungi, which colonize grapes, must and wine. Understanding their wine-relevant activities is essential to improving the selection and management of novel starter cultures and consequently wine quality. In contrast to previous publications, this book consistently focuses on the biology of wine-associated microbes. An international expert board of wine researchers describes the relevant systematic, ecological, physiological and genetic aspects of wine microbiology. The diversity of wine-related species, their energy, primary and secondary metabolism are important topics that have significant impacts on aroma production and off-flavour formation. The growth management of microbial species, stimulating and inhibitory growth factors and cell-cell interactions are also discussed; chapters on modern molecular and maintenance methods including rapid and real-time identification round off the book.

Microbial cell wall structures play a significant role in maintaining cells’ shape, as protecting layers against harmful agents, in cell adhesion and in positive and negative biological activities with host cells. All prokaryotes, whether they are bacteria or archaea, rely on their surface polymers for these multiple functions. Their surfaces serve as the indispensable primary interfaces between the cell and its surroundings, often mediating or catalyzing important interactions.Prokaryotic Cell Wall Compounds summarizes the current state of knowledge on the prokaryotic cell wall. Topics concerning bacterial and archaeal polymeric cell wall structures, biological activities, growth and inhibition, cell wall interactions and the applications of cell wall components, especially in the field of nanobiotechnology, are presented.
