This book was released on 2012-12-06 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: Autotrophic and methylotrophic microorganisms are able to grow at the expense of one-carbon compounds (e.g. carbon dioxide, formaldehyde) as the principal carbon sources for the synthesis of cell material, using light, inorganic compounds or one-carbon compounds as energy sources. The study of the special adaptations required in aerobic and anaerobic microorganisms to sustain an autotrophic or methylotrophic mode of life is a fascinating field of research for scientists from various disciplines. Current research efforts not only focus on fundamental aspects, i.e. metabolic pathways and their regulation, ecology, energy conversion and genetics, but also the possible application of these organisms, in waste water treatment, degradation of xenobiotics, single-cell protein production, as biocatalysts for the production of fine chemicals, draws strong attention. The aim of this series is to provide annual reviews on the biochemistry, physiology, ecology, genetics, and application of microbial autotrophs and methylotrophs. The scope of the series includes all aspects of the biology of these microbes, and will deal with phototrophic and chemolithotrophic prokaryotic autotrophs, carboxydobacteria, acetogenic-, methanogenic- and methylotrophic bacteria, as well as methylotrophic eukaryotes. The exciting advances made in recent years in the study of these organisms is reflected in the chapters of this first volume which have been written by experts in the field. We would like to express our sincere thanks to all the contributors for their stimulating and comprehensive chapters.

Download or read book Molecular Mechanisms in Yeast Carbon Metabolism written by Jure Piškur and published by Springer. This book was released on 2014-05-06 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This book has been written for students who are taking a course in bacterial metabolism. I hope, however, that scholars will also find it useful either as a help in teaching bacterial metabolism or as a review on the special aspects of metabolism in bacteria. The concept of this book results from my experience in teaching bacterial metabolism. In the first chapters the principal reactions of the energy and biosynthetic metabolism have been discussed using Escherichia coli as a model organism. Then the diversity of aerobic metabolism has been out lined. Following a brief description of the regulation of the level and the activity of enzymes in bacteria the characteristic features of fermentative, chemolithotrophic and phototrophic metabolism have been discussed. Finally, the last chapter has been devoted to nitrogen fixation. Throughout the text I have tried not only to describe metabolic pathways and enzyme reactions but also to elucidate the physiology of the microorganisms which carry out all these metabolic reactions. Two comments regarding the formulas used in this book are necessary.

Download or read book Size Limits of Very Small Microorganisms written by National Research Council and published by National Academies Press. This book was released on 1999-10-13 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: How small can a free-living organism be? On the surface, this question is straightforward-in principle, the smallest cells can be identified and measured. But understanding what factors determine this lower limit, and addressing the host of other questions that follow on from this knowledge, require a fundamental understanding of the chemistry and ecology of cellular life. The recent report of evidence for life in a martian meteorite and the prospect of searching for biological signatures in intelligently chosen samples from Mars and elsewhere bring a new immediacy to such questions. How do we recognize the morphological or chemical remnants of life in rocks deposited 4 billion years ago on another planet? Are the empirical limits on cell size identified by observation on Earth applicable to life wherever it may occur, or is minimum size a function of the particular chemistry of an individual planetary surface? These questions formed the focus of a workshop on the size limits of very small organisms, organized by the Steering .Group for the Workshop on Size Limits of Very Small Microorganisms and held on October 22 and 23, 1998. Eighteen invited panelists, representing fields ranging from cell biology and molecular genetics to paleontology and mineralogy, joined with an almost equal number of other participants in a wide-ranging exploration of minimum cell size and the challenge of interpreting micro- and nano-scale features of sedimentary rocks found on Earth or elsewhere in the solar system. This document contains the proceedings of that workshop. It includes position papers presented by the individual panelists, arranged by panel, along with a summary, for each of the four sessions, of extensive roundtable discussions that involved the panelists as well as other workshop participants.

Download or read book Metabolism of One Carbon C1 and Methylated Compounds in SAR11 Bacteria written by Jing Sun and published by . This book was released on 2014 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: SAR11 Alphaproteobacteria are the most abundant aerobic chemoheterotrophs in ocean surface waters. Previous studies have indicated SAR11 cells play an important role in marine carbon cycling and consume up to half of some common dissolved organic compounds, such as amino acids. During sequencing of the first SAR11 genome, genes for the oxidation of one carbon (C1) and methylated compounds were observed, which is very uncommon in proteobacteria, with the exception of methylotrophic species. The goal of this research was to study the metabolism of C1 and methylated compounds in SAR11, and to explore the implications of this for understanding the cycling of dissolved organic matter (DOM) in the oceans. Metabolic reconstruction from genome sequences and physiological experiments showed that SAR11 can utilize a variety of C1 and methylated compounds. The data showed that SAR11 strain HTCC1062 can oxidize methanol, formaldehyde, methylamine and methyl groups from glycine betaine (GBT), trimethylamine (TMA), trimethylamine N-oxide (TMAO), and dimethylsulfoniopropionate (DMSP). Interestingly, in addition to demethylating DMSP, strain HTCC1062 cleaved DMSP to the climatically active gas dimethyl sulfide (DMS) using a novel DMSP lyase. We propose that SAR11 cleaves DMSP to DMS when intracellular DMSP concentrations rise above a threshold, but below that threshold DMSP is channeled through the demethylation pathway to produce methanethiol that is used as a source of sulfur for growth. Investigation of transcriptional responses to five C1 compounds and methylated compounds revealed only a single case in which a gene was upregulated. The gene annotated as monomeric sarcosine oxidase (SAR11_1304) was upregulated in response to TMAO addition. SAR11_1304 was cloned and overexpressed in Escherichia. coli, and in vitro enzymatic assays showed that this protein has TMAO demethylase and dimethylamine monooxygenase activity, indicating it functions in the degradation pathway for TMAO. Overall, the data presented here reveal diverse metabolism in SAR11 for utilization of a variety of C1 and methylated compounds. This research provides insight into the metabolism of SAR11 and enhances understanding of the broad success of this ecologically significant organism. This work also indicates a surprisingly large role for C1 and methylated compounds in marine systems, and shows that broad insights into carbon cycling by marine microbes can be obtained by physiological experimentation based on genome predictions.
Download or read book Molecular Basis of Microbial One Carbon Metabolism 2008 Gordon Research Conference July 20 25 2008 written by and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: One-carbon (C-1) compounds play a central role in microbial metabolism. C-1 compounds include methane, carbon monoxide, CO2, and methanol as well as coenzyme-bound one-carbon compounds (methyl-B12, CH3-H4folate, etc). Such compounds are of broad global importance because several C-1 compounds (e.g., CH4) are important energy sources, some (e.g., CO2 and CH4) are potent greenhouse gases, and others (e.g., CH2Cl2) are xenobiotics. They are central in pathways of energy metabolism and carbon fixation by microbes and many are of industrial interest. Research on the pathways of one-carbon metabolism has added greatly to our understanding of evolution, structural biology, enzyme mechanisms, gene regulation, ecology, and applied biology. The 2008 meeting will include recent important findings in the following areas: (a) genomics, metagenomics, and proteomic studies that have expanded our understanding of autotrophy and C-1 metabolism and the evolution of these pathways; (b) redox regulation of carbon cycles and the interrelationship between the carbon cycle and other biogeochemical cycles (sulfur, nitrogen, oxygen); (c) novel pathways for carbon assimilation; (d) biotechnology related to C-1 metabolism; (e) novel enzyme mechanisms including channeling of C-1 intermediates during metabolism; and (f) the relationship between metal homeostasis and the global carbon cycle. The conference has a diverse and gender-balanced slate of speakers and session leaders. The wide variety of disciplines brought to the study of C-1 metabolism make the field an excellent one in which to train young researchers.
