Book Description
Yeast is one of the most studied laboratory organisms and represents one of the most central models to understand how any eukaryote cell works. On the other hand, yeast fermentations have for millennia provided us with a variety of biotech products, like wine, beer, vitamins, and recently also with pharmaceutically active heterologous products and biofuels. A central biochemical activity in the yeast cell is the metabolism of carbon compounds, providing energy for the whole cell, and precursors for any of the final fermentation products. A complex set of genes and regulatory pathways controls the metabolism of carbon compounds, from nutrient sensing, signal transduction, transcription regulation and post-transcriptional events. Recent advances in comparative genomics and development of post-genomic tools have provided further insights into the network of genes and enzymes, and molecular mechanisms which are responsible for a balanced metabolism of carbon compounds in the yeast cell, and which could be manipulated in the laboratory to increase the yield and quality of yeast biotech products. This book provides a dozen of most comprehensive reviews on the recent developments and achievements in the field of yeast carbon metabolism, from academic studies on gene expression to biotechnology relevant topics.

Book Description
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.

Book Description
This textbook aims to describe the fascinating area of eukaryotic gene regulation for graduate students in all areas of the biomedical sciences. Gene expression is essential in shaping the various phenotypes of cells and tissues and as such, regulation of gene expression is a fundamental aspect of nearly all processes in physiology, both in healthy and in diseased states. This pivotal role for the regulation of gene expression makes this textbook essential reading for students of all the biomedical sciences, in order to be better prepared for their specialized disciplines. A complete understanding of transcription factors and the processes that alter their activity is a major goal of modern life science research. The availability of the whole human genome sequence (and that of other eukaryotic genomes) and the consequent development of next-generation sequencing technologies have significantly changed nearly all areas of the biological sciences. For example, the genome-wide location of histone modifications and transcription factor binding sites, such as provided by the ENCODE consortium, has greatly improved our understanding of gene regulation. Therefore, the focus of this book is the description of the post-genome understanding of gene regulation. The purpose of this book is to provide, in a condensed form, an overview on the present understanding of the mechanisms of gene regulation. The authors are not aiming to compete with comprehensive treatises, but rather focus on the essentials. Therefore, the authors have favored a high figure-to-text ratio following the rule stating that “a picture tells more than thousand words”. The content of the book is based on the lecture course, which is given by Prof. Carlberg since 2001 at the University of Eastern Finland in Kuopio. The book is subdivided into 4 sections and 13 chapters. Following the Introduction there are three sections, which take a view on gene regulation from the perspective of transcription factors, chromatin and non-coding RNA, respectively. Besides its value as a textbook, Mechanisms of Gene Regulation will be a useful reference for individuals working in biomedical laboratories.

Book Description
The processes by which the budding yeast Saccharomyces cerevisiae metabolizes carbon sources by both fermentation and respiration have been studied for more than a century. Yeast metabolism has been used both industrially, for the production of important molecules such as ethanol, and as a model for basic scientific research. Applied scientists have studied yeast metabolism to create and optimize novel metabolic phenotypes not naturally found in Saccharomyces yeasts. In parallel, basic scientists have used yeast as a model to understand fundamental processes such as evolutionary adaptation, as well as the pathways of carbon metabolism themselves. There are many unanswered questions in both of these fields, some of which I have addressed in this work. With respect to the industrial importance of yeast, I asked whether there are naturally existing Saccharomyces yeasts that can metabolize the five-carbon sugars important for lignocellulosic ethanol production (such as xylose), and, if so, what is the genetic basis for their phenotypes? Having characterized natural genetic variation in xylose metabolism, I also wanted to understand something more fundamental about how carbon metabolism can adapt, including the molecular nature of adaptations to selection on a limiting carbon source. Specifically, I asked what is the niche breadth of, and are there genetic trade-offs in, yeast that have been evolved under glucose-limitation? I have used a combination of classical genetics, physiology, and high-throughput genomics to answer these two questions. I have discovered novel xylose-utilizing Saccharomyces yeasts and have shed considerable light on the genetic basis for their phenotypes. In addition, I have discovered at least one trade-off for adaptation to limiting glucose, namely that amplification of the hexose-transporter genes HXT6 and HXT7 causes reduced fitness in carbon-rich environments. These two projects highlight two major spheres of Saccharomyces research, and they provide key answers to outstanding questions in both fields.
