Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the diversity of yeasts in aquatic and terrestrial ecosystems, including the association of yeasts with insects, invertebrate and vertebrate animals. It offers an overview of the knowledge accumulated in the course of more than 60 years of research and is closely connected with the volume Yeasts in Natural Ecosystems: Ecology by the same editors. In view of the rapid decline of many natural habitats due to anthropogenic activities and climate change, the need to study biodiversity is pressing. Rising temperatures threaten species inhabiting cold and aquatic environments, and species in terrestrial ecosystems are endangered by habitat fragmentation or loss. Most of our knowledge of intrinsic properties (autoecology) of yeasts reported throughout this book is derived from laboratory experiments with pure cultures. Accordingly, the importance of culture collections for ecological studies is highlighted by presenting an overview of worldwide available yeast strains and their origins. All of the chapters were written by leading international yeast research experts, and will appeal to researchers and advanced students in the field of microbial diversity.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents an up-to-date review of the ecology of yeast communities in natural ecosystems. It focuses on their biological interactions, including mutualism, parasitism, commensalism and antagonistic interactions, and is closely connected with the volume Yeasts in Natural Ecosystems: Diversity by the same editors. Yeasts are the smallest eukaryotic organisms successfully growing under a wide range of environmental conditions. They constantly modify the environment through their own metabolic activities. Although yeasts are among the earlier colonizers of nutrient-rich substrates, their role in ecosystem processes is not limited to the consumption and transformation of simple sugars. They also engage in close relationships with animals, plants and other fungi in the environment as mutualists, competitors, parasites and pathogens. This book reviews the diversity of biological interactions and roles of yeasts in ecosystems and summarises recent concepts and tools developed in community ecology. All of the chapters were written by leading international yeast research experts, and will appeal to researchers and advanced students in the field of microbial ecology.

Available in PDF, EPUB and Kindle. Book excerpt: This book brings together and updates the latest information on the diversity of yeasts, their molecular features and their applications in the welfare of mankind. Yeasts are eukaryotic microfungi widely found in natural environments, including those with extreme conditions such as low temperatures, low oxygen levels and low water availability. To date, approximately 2,000 of the estimated 30,000 to 45,000 species of yeast on Earth, belonging to around 200 genera have been described. Although there are a few that are opportunistic human and animal pathogens, the vast majority of yeasts are beneficial, playing an important role in the food chain and in the carbon, nitrogen and sulphur cycles. In addition, yeasts such as Saccharomyces cerevisiae, Hansenula polymorpha and Pichia pastoris are used in expressing foreign genes to produce proteins of pharmaceutical interest. A landmark in biotechnology was reached in 1996 with the completion of sequencing of the entire S. cerevisiae genome, and it has now become a central player in the development of an entirely new approach to biological research and synthetic biology. The sequencing of genomes of several yeasts including Schizosaccharomyces pombe, Candida albicans and Cryptococcus neofromans has also recently been completed. candida albicans="" and="" p/pp

Download or read book Cold adapted Yeasts written by Pietro Buzzini and published by Springer Science & Business Media. This book was released on 2013-10-07 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: Yeasts are a versatile group of eukaryotic microorganisms, exhibiting heterogeneous nutritional profiles and an extraordinary ability to survive in a wide range of natural and man-associated ecosystems, including cold habitats. Cold-adapted yeasts inhabit numerous low-temperature environments where they are subjected to seasonal or permanent cold conditions. Hence, they have evolved a number of adaptation strategies with regard to growth and reproduction, metabolic activities, survival and protection. Due to their distinctive ability to thrive successfully at low and even subzero temperatures, cold-adapted yeasts are increasingly attracting attention in basic science and industry for their enormous biotechnological potential. This book presents our current understanding of the diversity and ecology of cold-adapted yeasts in worldwide cold ecosystems, their adaptation strategies, and their biotechnological significance. Special emphasis is placed on the exploitation of cold-adapted yeasts as a source of cold-active enzymes and biopolymers, as well as their benefits for food microbiology, bioremediation and biocontrol. Further, aspects of food biodeterioration are considered.

This book was released on 2022-03-15 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since ancient times, yeasts have been used for brewing and breadmaking processes. They now represent a flagship organism for alcoholic fermentation processes. The ubiquity of some yeast species also offers microbiologists a heterologous gene-expression platform, making them a model organism for studying eukaryotes. Yeasts: from Nature to Bioprocesses brings together information about the origin and evolution of yeasts, their ecological relationships, and the main taxonomic groups into a single volume. The book initially explores six significant yeast genera in detailed chapters. The book then delves into the main biotechnological processes in which both prospected and engineered yeasts are successfully employed. Yeasts: from Nature to Bioprocesses, therefore, elucidates the leading role of these single-cell organisms for industrial microbiology in environmental, health, social, and economic terms. This book is a comprehensive, multidisciplinary resource for general readers as well as scholars of all levels who want to know all about yeast microbiology and their industrial applications.

This book was released on 2013-03-09 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Guide to the World of the Yeasts J. F. T. Spencer and D. M. Spencert As the well-known authority on yeasts, the late Professor Rose, frequently pointed out, it is impossible for one person to present, in a single volume, the details of the life, composiotion, habitats, relationships, and actual and potential uses to man kind of the 500 (at last count) known species of yeasts. This book confirms the truth of this statement. However, our aim is actually more modest than that, and this book is an attempt to introduce the general reader, and possibly some inter ested specialists, to the lives of the yeasts in their natural and more artificial habitats, their use by human beings, and to give some idea of the wonderfully complex activities within the yeast cell, the characteristics of the metabolism and molecular biology of yeasts, and the applications of these characteristics to life in the present-dayworld ofhuman existence. The book proceeds from a brief chapter on what is and is not known of the origins and early history of the yeasts, through a description of their classification, relationships, habitats and general life style, their external morphology and internal structures and mechanisms within their cells, the regulatory mechanisms controlling processes such as signal transmis sion, mating, cell fusion, and many others.

Book excerpt: 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.

Download or read book Exploring the Drosophila yeast Mutualism in Natural Contexts written by Allison Quan and published by . This book was released on 2018 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mutualisms are among the most ubiquitous interactions in nature yet the general rules governing them have remained elusive. The natural mutualism between fruit flies and yeast, two common model organisms in molecular biology, is a particularly useful relationship for investigating these parameters. Drosophila feed on yeasts throughout their entire lifecycle and nonmotile yeasts depend on Drosophila to vector them to new, sugar-rich substrates. In the laboratory, Drosophila melanogaster can discriminate between and prefer different strains of Saccharomyces cerevisiae. However, in nature, Drosophila are associated with a variety of yeast species in addition to S. cerevisiae. The efforts detailed in this thesis are focused on characterizing the natural associations between wild Drosophila and yeast and testing the relevance of the fine-scale specificity between flies and yeast observed in the laboratory under more natural contexts. First, I present a detailed dissection of the associations between Drosophila and natural yeasts over two harvest seasons in organic wineries. Using targeted, amplicon sequencing methods, I found that the fungal communities vectored by Drosophila in wineries are distinct between winery microhabitats. However, the structure in these fungal communities is not a direct result of Drosophila behavior. Instead, a diversity of yeast species, even those that are not commonly associated with flies, are adequate partners in the fly-yeast mutualism at a wide range of relevant temperatures. While many yeast species can stimulate oviposition in Drosophila, ovipositional responses vary depending on the volatile profile emitted by a particular yeast species. Using gas chromatography-mass spectrometry and synthetic compounds, I found that a minimal blend of isoamyl acetate, acetic acid, 2-phenylethyl ester, and ethanol is sufficient for stimulating oviposition. However, the strength of the oviposition response is dependent on the volatile composition of the overall blend. Flies initially locate yeast through olfaction and a large portion of D. melanogaster odorant receptors are dedicated to detecting yeast metabolites. Kelly Schiabor, a former graduate student in the lab, demonstrated a correlation between two allelic variants of the odorant receptor 22 (Or22) in D. melanogaster and sensitivity to the volatiles produced by yeast grown under different nitrogen conditions. In collaboration with Carolyn Elya, another graduate student in the lab, I tested the hypothesis that the chimeric allele of Or22 confers heightened sensitivity to yeast grown on sugar-rich but nitrogen-limited substrates (YVN), a nutrient composition much like a natural, fruity substrate. Through extensive genotyping of natural populations, bidirectional crosses between chimeric and non-chimeric lines, and functional allele replacement of a non-chimeric Or22 allele with a chimeric allele, we found that Or22 alone cannot account for behavioral sensitivity to YVN. Even so, the signs of selection at the Or22 locus across wild D. melanogaster populations suggest that this receptor confers some kind of adaptive function in wild flies. Because wineries are not purely natural ecosystems, I next characterized the fly-yeast mutualism in Hawaiian Drosophila. The Hawaiian Drosophila are a diverse species group that has radiated across the Hawaiian Islands and exhibit very specific host plant adaptations. It has been hypothesized that the microbial communities on host plants, rather than host plants themselves, mediate host plant discrimination in Hawaiian Drosophila. I characterized the fungal communities associated with three closely related species of Hawaiian Drosophila and their respective host plants but found no clear association between the fungi associated with flies and host plants. However, the yeast species isolated from host plants and flies produce distinct volatile profiles, suggesting that different yeast species would affect the overall volatile bouquet of a plant substrate. Unfortunately, direct behavioral assays were not possible because the Hawaiian Drosophila-yeast system is limited by sample size and the ability to rear healthy fly populations in the laboratory. Nonetheless, the role of fungi in Hawaiian Drosophila host plant discrimination remains an ecologically significant question and an open area of investigation given the appropriate resources. Initially, the range of suitable yeast species in the fly-yeast mutualism was a surprising observation of these studies. However, this flexibility is clearly beneficial to the fitness of both flies and yeast from an evolutionary standpoint, as both organisms exist in dynamic environments. Even though their mutualism is nonspecific, both flies and yeast have continually coevolved conserved mechanisms and fine-tuned behaviors for ensuring a close association with each other.
