Available in PDF, EPUB and Kindle. Book excerpt: Recent economic trends, especially the worldwide decline in oil prices, and an altered political climate in the United States have combined to bring about major reductions in research on renewable energy resources. Yet there is no escaping the "facts of life" with regard to these resources. The days of inexpensive fossil energy are clearly numbered, the credibility of nuclear energy has fallen to a new low, and fusion energy stands decades or more from practical realization. Sooner than we may wish ,we will have to turn to renewable raw materials - plant "biomass" and, especially, wood - as significant suppliers of energy for both industry and everyday needs. It is therefore especially important to have a single, comprehensive and current source of information on a key step in any process for the technological exploitation of woody materials, cellulose hydrolysis. Further more, it is essential that any such treatment be unbiased with respect to the two methods - chemical and biochemical - for the breakdown of cellulose to sugars. Researchers on cellulose hydrolysis have frequently been chided by persons from industry, especially those individuals concerned with determining the economic feasibility of various technological alternatives. They tell us that schemes for the utilization of wood and other such resources fly in the face of economic realities.

This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Cellulose is the most abundant biomolecule on Earth and is composed of chains of glucose, but its depolymerization for use in the production of renewable bioenergy and biomaterials is inefficient. To better understand the mechanisms of cellulose degradation by cellobiohydrolases, a class of enzymes that cleave cellulose into cellobiose dimers, we characterized accessory enzymes that act on cellulose in combination with Trichoderma reesei Cel7A, a cellobiohydrolase that targets the reducing ends of glucan chains in cellulose. The accessory enzymes studied include endo-1,4-[beta]-D-glucanase (Cel7B) from Trichoderma longibrachiatum and Cel6A, a cellobiohydrolase II. Cel7B randomly cleaves cellulose to produce additional binding sites for other cellulases, whereas Cel6A cleaves cellobiose units from the nonreducing ends of glucan chains in cellulose. By measuring reducing end production in reactions between cellulose from Acetobacter and these enzymes, we found that although the addition of Cel7B with Cel7A significantly enhances cellulose hydrolysis, the enzyme appears to act in an additive manner rather than a synergistic (multiplicative) one. Conversely, Cel6A appears to act synergistically with Cel7A at varying concentrations, resulting in more cellulose hydrolysis by the enzyme mixture than the sum of the two enzymes alone. Further experiments to test three-enzyme cocktails containing each of the previous enzymes indicate that combining all three cellulases increases synergy above that observed for each two-enzyme combination. These data will be used to develop biochemical models to help explain the single-molecule behaviors of these enzymes as they degrade cellulose alone or in concert, as observed using a newly developed SCATTIRSTORM microscope.

Available in PDF, EPUB and Kindle. Book excerpt: FROM THE AUTHOR'S PREFACE This book . . . is focused on the structure and function relationships of the four major hydrolytic enzymes, cellulases, cellobiohydrolases, b-glucosidases, and xylanases as it relates to their mechanism of action. It should be of interest to biotechnologists and industrial researchers interested in manipulating these enzymes to their full potential as catalysts for various current and new applications. It begins with an overview of the nature of cellulose and heteroxylan, followed by a description of the enzymes involved in its hydrolysis, their general structure, characteristics, and classification. Chapter 3 discusses how these various enzymes are integrated and associated for the efficient solubilization of cellulose and heteroxylan. This includes a review of the literature concerning the cellulosomes and other cellulolytic complexes. The chapter on production and purification provides an overview of this subject matter. . . . These first four chapters thus set the stage for the more comprehensive discussion of the mechanism of action of each of the primary hydrolases which follows. . . . [T]he data pertaining to the catalytic mechanism of both the retaining and inverting forms of these enzymes since such studies were initiated on cellulases . . . in 1954 is reviewed in Chapter 5. The book concludes with an overview of the mode of action of the enzymes and a discussion, citing a few examples, of how the modern methods of molecular biology, enzymology, and X-ray crystallography are being used to manipulate selected enzymes for a variety of biotechnological and industrial purposes. The information in this new book will be of value to scientists and researchers working in the areas of biochemistry, botany, crop science, ecology, microbiology and mycology, in addition to those in the forestry and forest product industries.
Download or read book Advances in Enzymic Hydrolysis of Cellulose and Related Materials written by Elwyn T. Reese and published by Elsevier. This book was released on 2013-10-22 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in Enzymic Hydrolysis of Cellulose and Related Materials documents the proceedings of a symposium held in March 1962. This book emphasizes the interests of contributors actively engaged in production and properties of the enzymes and cellulose decomposition. Despite the significance of enzymes, relatively little work has been done on this group of enzymes, which include cellulases, hemicellulases, xylanases, disaccharidases, and glycosidases. This compilation aims to have the biological aspects of celluloses and hemicelluloses recognized under the cellulose field, and the cellulases to be considered in future books about cellulose and wood. Other topics discussed in this selection include structural features of cellulose that influence its susceptibility to enzymatic hydrolysis; purification of cellulase and related enzymes; endwise degradation of cellulose; and applications for cellulases. This publication is beneficial to students and researchers conducting work on enzymes and cellulose decomposition.
Download or read book Recent Progress in Bioconversion of Lignocellulosics written by G.T. Tsao and published by Springer. This book was released on 2003-06-30 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume describes recent advances in the bioconversion of lignocellulosics. It starts with two articles on genetics and properties of cellulases and their re- tion kinetics and mechanisms. The cost of cellulases has been a hindrance to large scale use of enzymatic hydrolysis. Two articles on cellulase production by submerged fermentation and by solid state fementation are included to describe the state of the art in this area. Dilute acid hydrolysis of cellulose continues to be of interest as well as potentially useful. The most recent advances in this area is also covered. A great deal of progress has been made in genetic engineering for improved regulation of xylose fermentation by yeasts. An article on genetically engineered Saccharomyces for simulteaneous fermentation of glucose and xylose describes the importance advances made in production of fuel ethanol from lignocellulosic biomass. In recent years, there has been increasing interests in recycling and the reuse of scrap paper as well as environment considerations. A contribution is presented which describes the research perspectives in that area. Finally, recent advances in the use of lignocellulosic biomass for the p- duction of ethanol and organic acids are presented in two articles. Renewable resources are inevitably of great importance in the years to come. There is a never-ending search for better living conditions for human beings. The more resource materials can be recycled, the richer we will be.
