Available in PDF, EPUB and Kindle. Book excerpt: Carbon is the chemical scaffolding of life and civilization; indeed, the great cycle by which carbon moves through organisms, ground, water, and atmosphere has long been a kind of global respiration system that helps keep Earth in balance. And yet, when we hear the word today, it is more often than not in a crisis context. Journalist Roston evokes this essential element, from the Big Bang to modern civilization. Charting the science of carbon--how it was formed, how it came to Earth--he chronicles the often surprising ways mankind has used it over centuries, and the growing catastrophe of the industrial era, leading our current attempt to wrestle the Earth's geochemical cycle back from the brink. Blending the latest science with original reporting, Roston makes us aware of the seminal impact carbon has, and has had, on our lives.--From publisher description.

Available in PDF, EPUB and Kindle. Book excerpt: There are currently intense efforts devoted to understand plant respiration (from genes toecosystems) and its regulatory mechanisms; this is because respiratory CO2 productionrepresents a substantial carbon loss in crops and in natural ecosystems. Thus, in addition tomanipulating photosynthesis to increase plant biomass production, minimization ofrespiratory loss should be considered in plant science and engineering. However, respiratorymetabolic pathways are at the heart of energy and carbon skeleton production and therefore, itis an essential component of carbon metabolism sustaining key processes such asphotosynthesis. The overall goal of this book is to provide an insight in such interactions aswell as an up-to-date view on respiratory metabolism, taking advantage of recent advancesand concepts, from fluxomics to natural isotopic signal of plant CO2 efflux. It is thus a nonoverlapping,complement to Volume 18 in this series (Plant Respiration From Cell toEcosystem) which mostly deals with mitochondrial electron fluxes and plant-scale respiratorylosses.

This book was released on 1990-05-31 with total page 252 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.

Available in PDF, EPUB and Kindle. Book excerpt: Metabolic Ecology Most of ecology is about metabolism, the ways that organisms use energy and materials. The energy requirements of individuals (their metabolic rates) vary predictably with their body size and temperature. Ecological interactions are exchanges of energy and materials between organisms and their environments. Therefore, metabolic rate affects ecological processes at all levels: individuals, populations, communities and ecosystems. Each chapter focuses on a different process, level of organization, or kind of organism. It lays a conceptual foundation and presents empirical examples. Together, the chapters provide an integrated framework that holds the promise for a unified theory of ecology. The book is intended to be accessible to upper-level undergraduates and graduate students, but also of interest to senior scientists. Its easy-to-read chapters and clear illustrations can be used in lecture and seminar courses. This is an authoritative treatment that will inspire future generations to study metabolic ecology.

Download or read book Characterization of Carbon Metabolism in an Oleaginous Diatom Suitable for Commercial Production written by Jessica Campbell Traller and published by . This book was released on 2017 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: The realization of the environmental and economic impact that occurs from the release of carbon dioxide derived from fossil fuel has spurred technologies focused on renewable alternative energy production. The production of liquid based biofuel from microalgae has been one of the proposed solutions due to microalgae's high productivity per acre of land, its ability to accumulate large amounts of the precursor to biofuel, triacylglycerol, and its dependence on carbon dioxide, allowing for sequestration of anthropogenic CO2 from the atmosphere. The promise of microalgae as a feedstock for the large-scale commercial production of biofuel is impressive, however, there are significant advances in productivity still needed in order to make the solution economically and industrially feasible. For instance, the mechanisms that control triacylglycerol accumulation and cellular division in microalgae are still largely unknown. Moreover, most studies on these processes have been focused on model organisms for basic research, not on species that are industrially relevant. The immense diversity of algae as well as their complex evolutionary history indicates that molecular mechanisms controlling primary metabolism are not necessarily ubiquitous. Therefore, elucidation of carbon metabolism in a candidate species for commercial production is key for the biological comprehension within algal biofuel production. The main objective of this dissertation was to characterize primary carbon metabolism in the diatom Cyclotella cryptica, a species of microalgae with promise for large-scale industrial production. Chapter 1 investigated the neutral lipid accumulation response of C. cryptica through the comparison of two macronutrient starvation using imaging flow cytometry. Chapters 2 and 3 applied high-throughput sequencing technologies to identify the molecular and metabolic controls of triacylglycerol accumulation. The data presented in this dissertation will hopefully move this species and others closer to the economic feasibility of commercial scale algal biofuel by characterizing key areas of metabolism pertinent to triacylglycerol formation, providing genomic datasets necessary for the development of genetic engineering tools, and establishing a model for primary carbon metabolism in an industrially relevant species.

This book was released on 2017-03-15 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquatic microorganisms are tidily related to the carbon cycle in aquatic systems, especially in respect to its accumulation and emission to atmosphere. In one hand, the autotrophs are responsible for the carbon input to the ecosystems and trophic chain. On the other hand, the heterotrophs traditionally play a role in the carbon mineralization and, since microbial loop theory, may play a role to carbon flow through the organisms. However, it is not yet clear how the heterotrophs contribute to carbon retention and emission especially from tropical aquatic ecosystems. Most of the studies evaluating the role of microbes to carbon cycle in inland waters were performed in high latitudes and only a few studies in the tropical area. In the prospective of global changes where the warm tropical lakes and rivers become even warmer, it is important to understand how microorganisms behave and interact with carbon cycle in the Earth region with highest temperature and light availability. This research topic documented microbial responses to natural latitudinal gradients, spatial within and between ecosystems gradients, temporal approaches and temperature and nutrient manipulations in the water and in the sediment.

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.

Available in PDF, EPUB and Kindle. Book excerpt: To address the major role microorganisms play in the biogeochemical cycling of carbon and nutrients in the marine environment, the work presented in this dissertation uses a combination of geochemical and molecular biological techniques to investigate carbon and nitrogen metabolism in the planktonic microbial community of the deep ocean. A method was developed to isolate microbial DNA from the marine water column suitable for radiocarbon analysis, which was then applied to determine the sources of carbon fueling microbial production in the mesopelagic. Fresh organic matter delivered from sinking particles was confirmed as an important carbon source for free-living microbes, but the extent of autotrophic carbon fixation was also significant and variable with depth, highlighting the requirement for particle-delivered reduced nitrogen by the total microbial community in the deep ocean. Both findings stressed the importance of constraining particle-derived carbon and nitrogen flux to the deep ocean. The importance of methane as a carbon source in unique environments above cold methane seeps was examined using both stable carbon isotope measurements of microbial DNA and quantitative PCR of the gene encoding for particulate methane monooxygenase. The carbon isotope measurements showed that methane-carbon played an insignificant role in fueling planktonic microbial production in the deep water column just above methane seeps. The PCR measurements substantiated this result by showing that the methane oxidizing community represented only a small percentage of the microbial community in this environment. And finally, bacterial heterotrophic nitrate assimilation was studied and determined to increase with depth and/or nitrate concentration, but appeared to only be a possible nitrogen acquisition method for a small (> 1%) fraction of the bacterial community. Sequencing of the heterotrophic nitrate assimilation gene isolated from the marine environment further demonstrated that these genes were depth stratified. In addition both isotopic analyses and molecular biological techniques such as quantitative PCR indicated distinct differences between free-living and particle-attached microbial communities. Overall, future research efforts should be focused on expanding the current data set, constraining particle flux, and gaining a better understanding of microbial physiology, including in situ growth rates, in the subsurface marine environment.
