This book was released on 2022-02-10 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Metabolic engineering and biocatalysis aim to produce new value-added products from biological routes through careful and deliberate genetic engineering in different microbial chassis with suitable metabolic repertoire. Hitherto, the endeavor has largely been confined to the production of new products from glucose and a few other well characterized substrates. But, as the bioeconomy gains in importance and the world seeks to explore new sources of carbon as feedstocks, a possibility exists in developing alternative C2 compounds as feedstocks in contrast to the current reliance on C6 (glucose and fructose), C5 (xylose) and C3 (glycerol) substrates. Two potential C2 alternative substrates explored in this work are ethanol and ethylene glycol. Ethanol is a biofuel whose biotechnological potential has not been fully explored. In the first part of the book, the potential of using the NADH generated from a reconstructed ethanol utilization pathway to power a biotransformation reaction is explored in Escherichia coli. Experimental results indicate that ethanol utilization delivers higher biotransformation efficiency compared to state-of-the-art glucose dehydrogenase system, which confirmed theoretical predictions of relative efficiency of the two systems. Next, the book switches attention to ethylene glycol which could be derived as breakdown products of lignocellulosic waste or from plastic waste. Here, the proposal is to demonstrate the potential of an NADH generating ethylene glycol utilization pathway that terminates at glycolate to support biocatalytic reactions in E. coli. Subsequently, the two-step ethylene glycol utilization pathway would be extended to malate and 2-phosphoglycerate to help another biotechnology workhorse, Bacillus subtilis, to grow on ethylene glycol as the sole carbon source. Different connection points to central carbon metabolism would provide a natural experiment to decipher the relative efficiencies of activating tricarboxylic acid cycle and glycolysis in supporting cell growth, and illuminate insights into the relative efficiency and evolutionary importance of different branches of metabolism in B. subtilis. Finally, ethylene glycol utilization would be combined with product formation to help B. subtilis to synthesize green fluorescent protein using flux from the C2 alternative substrate. This system would provide a platform for examining the efficacy of different ethylene glycol utilization pathways and entry points in central carbon metabolism in synthesizing amino acids and proteins. Overall, this book hopes to explore the biotechnological potential of two alternative C2 substrates (ethanol and ethylene glycol) in biocatalysis and metabolic engineering from the substrate utilization perspective.
Download or read book Recent Advances in Biocatalysis and Metabolic Engineering for Biomanufacturing written by Eun Yeol Lee and published by MDPI. This book was released on 2019-09-23 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of biocatalysts, including enzymes and metabolically engineered cells, has attracted a great deal of attention in the chemical and bio-industry, because biocatalytic reactions can be conducted under environmentally-benign conditions and in more sustainable ways. The catalytic efficiency and chemo-, regio-, and stereo-selectivity of enzymes can be enhanced and modulated using protein engineering. Metabolic engineering seeks to enhance cellular biosynthetic productivity of target metabolites via controlling and redesigning metabolic pathways using multi-omics analysis, genome-scale modeling, metabolic flux control, and reconstruction of novel pathways. The aim of this book is to cover the recent advances in biocatalysis and metabolic engineering for biomanufacturing of biofuels, chemicals, biomaterials, and pharmaceuticals. Reviews and original research articles on the development of new strategies to improve the catalytic efficiency of enzymes, biosynthetic capability of cell factories, and their applications in production of various bioproducts and chemicals are included.

Download or read book Enzyme Biocatalysis written by Andrés Illanes and published by Springer Science & Business Media. This book was released on 2008-06-19 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was written with the purpose of providing a sound basis for the design of enzymatic reactions based on kinetic principles, but also to give an updated vision of the potentials and limitations of biocatalysis, especially with respect to recent app- cations in processes of organic synthesis. The ?rst ?ve chapters are structured in the form of a textbook, going from the basic principles of enzyme structure and fu- tion to reactor design for homogeneous systems with soluble enzymes and hete- geneous systems with immobilized enzymes. The last chapter of the book is divided into six sections that represent illustrative case studies of biocatalytic processes of industrial relevance or potential, written by experts in the respective ?elds. We sincerely hope that this book will represent an element in the toolbox of gr- uate students in applied biology and chemical and biochemical engineering and also of undergraduate students with formal training in organic chemistry, biochemistry, thermodynamics and chemical reaction kinetics. Beyond that, the book pretends also to illustrate the potential of biocatalytic processes with case studies in the ?eld of organic synthesis, which we hope will be of interest for the academia and prof- sionals involved in R&D&I. If some of our young readers are encouraged to engage or persevere in their work in biocatalysis this will certainly be our more precious reward.

Download or read book The Prokaryotes written by Edward F. DeLong and published by Springer. This book was released on 2014-10-13 with total page 567 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Prokaryotes is a comprehensive, multi-authored, peer reviewed reference work on Bacteria and Achaea. This fourth edition of The Prokaryotes is organized to cover all taxonomic diversity, using the family level to delineate chapters. Different from other resources, this new Springer product includes not only taxonomy, but also prokaryotic biology and technology of taxa in a broad context. Technological aspects highlight the usefulness of prokaryotes in processes and products, including biocontrol agents and as genetics tools. The content of the expanded fourth edition is divided into two parts: Part 1 contains review chapters dealing with the most important general concepts in molecular, applied and general prokaryote biology; Part 2 describes the known properties of specific taxonomic groups. Two completely new sections have been added to Part 1: bacterial communities and human bacteriology. The bacterial communities section reflects the growing realization that studies on pure cultures of bacteria have led to an incomplete picture of the microbial world for two fundamental reasons: the vast majority of bacteria in soil, water and associated with biological tissues are currently not culturable, and that an understanding of microbial ecology requires knowledge on how different bacterial species interact with each other in their natural environment. The new section on human microbiology deals with bacteria associated with healthy humans and bacterial pathogenesis. Each of the major human diseases caused by bacteria is reviewed, from identifying the pathogens by classical clinical and non-culturing techniques to the biochemical mechanisms of the disease process. The 4th edition of The Prokaryotes is the most complete resource on the biology of prokaryotes. The following volumes are published consecutively within the 4th Edition: Prokaryotic Biology and Symbiotic Associations Prokaryotic Communities and Ecophysiology Prokaryotic Physiology and Biochemistry Applied Bacteriology and Biotechnology Human Microbiology Actinobacteria Firmicutes Alphaproteobacteria and Betaproteobacteria Gammaproteobacteria Deltaproteobacteria and Epsilonproteobacteria Other Major Lineages of Bacteria and the Archaea

Available in PDF, EPUB and Kindle. Book excerpt: The practice of biotechnology, though different in style, scale and substance in globalizing science for development involves all countries. Investment in biotechnology in the industrialised, the developing, and the least developed countries, is now amongst the widely accepted avenues being used for economie development. The simple utilization of kefir technology, the detoxification of injurious chemical pesticides e.g. parathion, the genetic tailoring of new crops, and the production of a first of a kind of biopharmaceuticals illustrate the global scope and content of biotechnology research endeavour and effort. In the developing and least developed nations, and in which the 9 most populous countries· are encountered, problems concerning management of the environment, food security, conservation of human health resources and capacity building are important factors that influence the path to sustainable development. Long-term use of biotechnology in the agricultural, food, energy and health sectors is expected to yield a windfall of economic, environmental and social benefits. Already the prototypes of new medicines and of prescription fruit vaccines are available. Gene based agriculture and medieine is increasingly being adopted and accepted. Emerging trends and practices are reflected in the designing of more efficient bioprocesses, and in new research in enzyme and fermentation technology, in the bioconversion of agro industrial residues into bio-utility products, in animal healthcare, and in the bioremediation and medical biotechnologies. Indeed, with each new day, new horizons in biotechnology beckon.

This book was released on 2009-04-24 with total page 747 pages. Available in PDF, EPUB and Kindle. 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 Microbial Enzymes and Biotechnology written by W.M. Fogarty and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biotechnology is now one of the major growth areas in science and engineering and within this broad discipline enzyme technology is one of the areas earmarked for special and significant developments. This publication is the second edition of Microbial Enzymes and Biotechnol ogy which was originally published in 1983. In this edition the editors have attempted to bring together accounts (by the relevant experts) of the current status of the major areas of enzyme technology and specifically those areas of actual and/or potential commercial importance. Although the use of microbial enzymes may not have expanded at quite the rate expected a decade ago, there is nevertheless intense activity and considerable interest in the whole area of enzyme technology. Microbial enzymes have been used in industry for many centuries although it is only comparatively recently that detailed knowledge relating to their nature, properties and function has become more evident. Developments in the 1960s gave a major thrust to the use of microbial enzymes in industry. The commercial success of alkaline proteases and amyloglucosidases formed a bed-rock for subsequent research and development in the area.

Download or read book Bioreaction Engineering Principles written by Jens Nielsen and published by Springer. This book was released on 2012-12-06 with total page 537 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the second edition of the text "Bioreaction Engineering Principles" by Jens Nielsen and John Villadsen, originally published in 1994 by Plenum Press (now part of Kluwer). Time runs fast in Biotechnology, and when Kluwer Plenum stopped reprinting the first edition and asked us to make a second, revised edition we happily accepted. A text on bioreactions written in the early 1990's will not reflect the enormous development of experimental as well as theoretical aspects of cellular reactions during the past decade. In the preface to the first edition we admitted to be newcomers in the field. One of us (JV) has had 10 more years of job training in biotechnology, and the younger author (IN) has now received international recognition for his work with the hottest topics of "modem" biotechnology. Furthermore we are happy to have induced Gunnar Liden, professor of chemical reaction engineering at our sister university in Lund, Sweden to join us as co-author of the second edition. His contribution, especially on the chemical engineering aspects of "real" bioreactors has been of the greatest value. Chapter 8 of the present edition is largely unchanged from the first edition. We wish to thank professor Martin Hjortso from LSU for his substantial help with this chapter.
