This volume scopes several aspects of non-conventional yeast research prepared by the leading specialists in the field. An introduction on taxonomy and systematics enhances the reader’s knowledge on yeasts beyond established ones such as Saccharomyces cerevisiae. Biotechnological approaches that involve fungal utilization of unusual substrates, production of biofuels and useful chemicals as citric acid, glutathione or erythritol are discussed. Further, strategies for metabolic engineering based on knowledge on regulation of gene expression as well as sensing and signaling pathways are presented. The book targets researchers and advanced students working in Microbiology, Microbial Biotechnology and Biochemistry.

This is the first book to extensively and exclusively cover nonconventional yeasts - all yeasts other than S. cerevisiae and S. pombe. In addition to useful background information, the author includes detailed protocols allowing the investigation of basic and applied aspects for a wide range of these organisms. Due to the increasing importance of nonconventional yeasts in biotechnological applications, this book should become the standard reference for both pure and applied scientists working in the fields of microbiology and biochemistry.

I belie ve that the book would provide an overview of the recent developments in the domain of yeast research with some new ideas, which could serve as an inspiration and challenge for researchers in this field. Ne w Delhi Prof. Asis Datta Dec. 24, 2007 F ormer Vice-chancellor, JNU Director, NCPGR (New Delhi) Pr eface Yeasts are eukaryotic unicellular microfungi that are widely distributed in the natural environments. Although yeasts are not as ubiquitous as bacteria in the na- ral environments, they have been isolated from terrestrial, aquatic and atmospheric environments. Yeast communities have been found in association with plants, a- mals and insects. Several species of yeasts have also been isolated from specialized or extreme environments like those with low water potential (e. g. high sugar/salt concentrations), low temperature (e. g. yeasts isolated from Antarctica), and low oxygen availability (e. g. intestinal tracts of animals). Around 1500 species of yeasts belonging to over 100 genera have been described so far. It is estimated that only 1% of the extant yeasts on earth have been described till date. Therefore, global efforts are underway to recover new yeast species from a variety of normal and extreme environments. Yeasts play an important role in food chains, and carbon, nitrogen and sulphur cycles. Yeasts can be genetically manipulated by hybridization, mutation, rare m- ing, cytoduction, spheroplast fusion, single chromosomal transfer and transfor- tion using recombinant technology. Yeasts (e. g.

This book provides a comprehensive overview on biotechnological applications of unicellular and multicellular fungi in a variety of industrial branches. Targeted genetic and metabolic engineering of fungi allows production of native and transgenic enzymes and proteins in industrial scales. Those most prominently find application in biorefineries for the production of value-added chemicals and biofuels, in the pharmaceutical industry as well as in biomedicine. Each chapter is dedicated to applications and potential beneficial use of particular strains of yeasts and filamentous fungi and their produced biomolecules. The book targets researchers from both academia and industry and graduate students working in microbial biotechnology.

Most information on yeasts derives from experiments with the conventional yeasts Saccaromyces cerevisiae and Schizossaccharomyces pombe, the complete nuclear and mitochondrial genome of which has also been sequenced. For all other non-conventional yeasts, investigations are in progress and the rapid development of molecular techniques has allowed an insight also into a variety of non-conventional yeasts. In this bench manual, over 70 practical protocols using 15 different non-conventional yeast species and in addition several protocols of general use are described in detail. All of these experiments on the genetics, biochemistry and biotechnology of yeasts have been contributed by renowned laboratories and have been reproduced many times. The reliable protocols are thus ideally suited also for undergraduate and graduate practical courses.

Yeast is one of the oldest domesticated organisms and has both industrial and domestic applications. In addition, it is very widely used as a eukaryotic model organism in biological research and has offered valuable knowledge of genetics and basic cellular processes. In fact, studies in yeast have offered insight in mechanisms underlying ageing and diseases such as Alzheimers, Parkinsons and cancer. Yeast is also widely used in the lab as a tool for many technologies such as two-hybrid analysis, high throughput protein purification and localization and gene expression profiling. The broad range of uses and applications of this organism undoubtedly shows that it is invalubale in research, technology and industry. Written by one of the world's experts in yeast, this book offers insight in yeast biology and its use in studying cellular mechanisms.

Yeast - Industrial Applications is a book that covers applications and utilities of yeasts in food, chemical, energy, and environmental industries collected in 12 chapters. The use of yeasts in the production of metabolites, enzymatic applications, fermented foods, microorganism controls, bioethanol production, and bioremediation of contaminated environments is covered showing results, methodologies, and processes and describing the specific role of yeasts in them. The traditional yeast Saccharomyces cerevisiae is complemented in many applications with the use of less known non-Saccharomyces yeasts that now are being used extensively in industry. This book compiles the experience and know-how of researchers and professors from international universities and research centers.
