Download or read book Overflow Metabolism written by Alexei Vazquez and published by Academic Press. This book was released on 2017-10-16 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Overflow Metabolism: From Yeast to Marathon Runners provides an overview of overflow metabolism, reviewing the major phenomenological aspects as observed in different organisms, followed by a critical analysis of proposed theories to explain overflow metabolism. In our ideal view of metabolism, we think of catabolism and anabolism. In catabolism nutrients break down to carbon dioxide and water to generate biochemical energy. In anabolism nutrients break down to generate building blocks for cell biosynthesis. Yet, when cells are pushed to high metabolic rates they exhibit incomplete catabolism of nutrients, with a lower energy yield and excretion of metabolic byproducts. This phenomenon, characterized by the excretion of metabolic byproducts that could otherwise be used for catabolism or anabolism, is generally known as overflow metabolism. Overflow metabolism is a ubiquitous phenotype that has been conserved during evolution. Examples are the acetate switch in the bacterium E. coli, Crabtree effect in unicellular eukaryote yeasts, the lactate switch in sports medicine, and the Warburg effect in cancer. Several theories have been proposed to explain this seemingly wasteful phenotype. Yet, there is no consensus about what determines overflow metabolism and whether it offers any selective advantage. - Includes examples of overflow metabolism and major phenomenological features - Features a critical view of proposed theories to explain overflow metabolism - Provides a summary of our preview work, proposing molecular crowding as the cause of overflow metabolism, together with new unpublished results

Download or read book Microbial Life History written by Steven A. Frank and published by Princeton University Press. This book was released on 2022-08-16 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: A powerful framework for understanding how natural selection shapes adaptation and biological design Design and diversity are the two great challenges in the study of life. Microbial Life History draws on the latest advances in microbiology to describe the fundamental forces of biological design and apply these evolutionary processes to a broad diversity of traits in microbial metabolism and biochemistry. Emphasizing how to formulate and test hypotheses of adaptation, Steven Frank provides a new foundation for exploring the evolutionary forces of design. He discusses the economic principles of marginal valuations, trade-offs, and payoffs in risky and random environments; the social aspects of conflict and cooperation; the demographic aspects of age and spatial heterogeneity; and the engineering control theory principles by which systems adjust to environments. Frank then applies these evolutionary principles to the biochemistry of microbial metabolism, providing the first comprehensive link between the forces that shape biological design and cellular energetics. Tracing how natural selection sculpts metabolism, Microbial Life History provides new perspectives on the life histories of organisms, from growth rate and survival to dispersal and defense against attack. Along the way, this incisive book addresses the conceptual and philosophical challenges confronting evolutionary biologists and other practitioners who study biological design and seek to apply its lessons.

Download or read book Dynamics of the Chemostat written by Abdelhamid Ajbar and published by CRC Press. This book was released on 2011-08-09 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: A ubiquitous tool in mathematical biology and chemical engineering, the chemostat often produces instabilities that pose safety hazards and adversely affect the optimization of bioreactive systems. Singularity theory and bifurcation diagrams together offer a useful framework for addressing these issues. Based on the authors’ extensive work in this field, Dynamics of the Chemostat: A Bifurcation Theory Approach explores the use of bifurcation theory to analyze the static and dynamic behavior of the chemostat. Introduction The authors first survey the major work that has been carried out on the stability of continuous bioreactors. They next present the modeling approaches used for bioreactive systems, the different kinetic expressions for growth rates, and tools, such as multiplicity, bifurcation, and singularity theory, for analyzing nonlinear systems. Application The text moves on to the static and dynamic behavior of the basic unstructured model of the chemostat for constant and variable yield coefficients as well as in the presence of wall attachment. It then covers the dynamics of interacting species, including pure and simple microbial competition, biodegradation of mixed substrates, dynamics of plasmid-bearing and plasmid-free recombinant cultures, and dynamics of predator–prey interactions. The authors also examine dynamics of the chemostat with product formation for various growth models, provide examples of bifurcation theory for studying the operability and dynamics of continuous bioreactor models, and apply elementary concepts of bifurcation theory to analyze the dynamics of a periodically forced bioreactor. Using singularity theory and bifurcation techniques, this book presents a cohesive mathematical framework for analyzing and modeling the macro- and microscopic interactions occurring in chemostats. The text includes models that describe the intracellular and operating elements of the bioreactive system. It also explains the mathematical theory behind the models.

Download or read book Metabolic Regulation and Metabolic Engineering for Biofuel and Biochemical Production written by Kazuyuki Shimizu and published by CRC Press. This book was released on 2017-07-12 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: The global warming problem is becoming critical year by year, causing climate disaster all over the world, where it has been believed that the CO2 gas emitted from the factories and the burning of fossil fuels may be one of the reasons of global warming. Moreover, the global stock of fossil fuels is limited, and may run out soon within several tens of years. Although wind, geo-thermal, and tide energies have been considered as clean energy sources, those depend on the land or sea locations and subject to the climate change. Biofuel and biochemical production from renewable bio-resources has thus been paid recent attention from environmental protection and energy production points of view, where the current chemical and energy producing plants can be also utilized with slight modification. The so-called 1st generation biofuels have been produced from corn starch and sugarcane in particular in USA and Brazil. However, this causes the problem of the so-called "food and energy issues" as the production scale increases. The 2nd generation biofuel production from lingo-cellulosic biomass or wastes has thus been paid recent attention. However, it requires energy intensive pretreatment for the degradation of lingo-cellulosic biomass, and the fermentation is slow due to low growth rate, and thus the productivity of biofuels and bio-chemicals is low. The 3rd generation biofuel production from photosynthetic organisms such as cyanobacteria and algae has been also paid attention, because such organisms can grow with only sun light and CO2 in the air, but the cell growth rate and thus the productivity of the fuels is significantly low. The main part or core of such production processes is the fermentation by micro-organisms. In particular, it is critical to properly understand the cell metabolism followed by the efficient metabolic engineering. The book gives comprehensive explanation of the cell metabolism and the metabolic regulation mechanisms of a variety of micro-organisms. Then the efficient metabolic engineering approaches are explained to properly design the microbial cell factories for the efficient cell growth and biofuel and biochemical production.
