This book was released on 2012-12-06 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: The oil crisis during the 1970s turned interest towards the utilization of renewable resources and towards lignocellulosics in particular. The 1970s were also the cradle period of biotechnology, and the years when biotechnical utilization of lignocellulosic waste from agriculture and forestry gained priori ty. This was a logical conclusion since one of nature's most important biologi cal reactions is the conversion of wood and other lignocellulosic materials to carbon dioxide, water and humic substances. However, while biotechnology in other areas like medicine and pharmacology concerned production of expen sive products on a small scale, biotechnical utilization and conversion of ligno cellulosics meant production of inexpensive products on a large scale. Biotechnical utilization of lignocellulosic materials is therefore a very difficult task, and the commercial utilization of this technology has not progressed as rapidly as one would have desired. One reason for this was the lack of basic knowledge of enzyme mechanisms involved in the degradation and conversion of wood, other lignocellulosics and their individual components. There are also risks associated with initiating a technical development before a stable platform of knowledge is available. Several of the projects started with en thusiasm have therefore suffered some loss of interest. Also contributing to this failing interest is the fact that the oil crisis at the time was not a real one. At present, nobody predicts a rapid exhaustion of the oil resources and fuel production from lignocellulosics is no longer a high priority.

Book Synopsis Biodegradation of Cellulose by : Anthony J. Clarke
Download or read book Biodegradation of Cellulose written by Anthony J. Clarke and published by CRC Press. This book was released on 1996-08-27 with total page 294 pages. 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.

Book Synopsis Biochemistry of microbial degradation by : Colin Ratledge
Download or read book Biochemistry of microbial degradation written by Colin Ratledge and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 598 pages. Available in PDF, EPUB and Kindle. Book excerpt: Life on the planet depends on microbial activity. The recycling of carbon, nitrogen, sulphur, oxygen, phosphate and all the other elements that constitute living matter are continuously in flux: microorganisms participate in key steps in these processes and without them life would cease within a few short years. The comparatively recent advent of man-made chemicals has now challenged the environment: where degradation does not occur, accumulation must perforce take place. Surprisingly though, even the most recalcitrant of molecules are gradually broken down and very few materials are truly impervious to microbial attack. Microorganisms, by their rapid growth rates, have the most rapid turn-over of their DNA of all living cells. Consequently they can evolve altered genes and therefore produce novel enzymes for handling "foreign" compounds - the xenobiotics - in a manner not seen with such effect in other organisms. Evolution, with the production of micro-organisms able to degrade molecules hitherto intractable to breakdown, is therefore a continuing event. Now, through the agency of genetic manipulation, it is possible to accelerate this process of natural evolution in a very directed manner. The time-scale before a new microorganism emerges that can utilize a recalcitrant molecule has now been considerably shortened by the application of well-understood genetic principles into microbiology. However, before these principles can be successfully used, it is essential that we understand the mechanism by which molecules are degraded, otherwise we shall not know where best to direct these efforts.
Book Synopsis Microbiology of Solid Waste by : Anna C. Palmisano
Download or read book Microbiology of Solid Waste written by Anna C. Palmisano and published by CRC Press. This book was released on 2020-07-09 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest in solid waste disposal has been growing since the early 1960s, when researchers emphasized the potential for solid waste to harbor pathogenic microorganisms. Since then, society has become more interested in the environmental impacts of solid waste treatment and disposal, and how biological processes are used to minimize these impacts. This new text provides a basic understanding of the unique microbial ecosystems associated with the decomposition of municipal solid waste (MSW). It addresses the challenges of sampling and assaying microbial activities in MSW and describes preferred methods. The decomposition of MSW under anaerobic conditions in landfills and digestors is described, as well as under aerobioconditions during composting. The Microbiology of Solid Wastes discusses the need to consider MSW as an integrated system of collection, recycling, treatment, and disposal. A better understanding of solid waste microbiology will contribute to safe and economical solid waste management. Microbiologists, environmental engineers, and solid waste managers will all find this a useful reference.
Book Synopsis Contribution of Oxidative Enzymes to the Degradation of Cellulose by Filamentous Fungi by : William Templeton Beeson

This book was released on 2011 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cost of cellulose degrading enzymes is still a major barrier to the economical production of liquid fuels from lignocellulose. Fungi play a central role in the degradation of plant biomass in terrestrial environments. They use a wide variety of secreted enzymes to break down biopolymers present in the plant cell wall. Here I report on the mechanisms of cellulose degradation used by Neurospora crassa, a model genetic organism, and Myceliopthora thermophila, a thermophilic fungus. Enzymes important for the degradation process were identified using a combination of transcriptomics, proteomics, genetics, and biochemistry. A key result from this work is that, in N. crassa and many other fungi, oxidative enzymes play a critical role in the depolymerization of cellulose. In contrast to the accepted models of oxidative cellulose degradation, via non-specific hydroxyl radical species, I found that in N. crassa, an oxidoreductase and several copper oxidases bind to cellulose and hydroxylate the substrate at specific positions leading to cleavage of the glycosidic bonds. This mode of action is orthogonal to that of traditional hydrolases and if used optimally in conjunction with other cellulases, could reduce the required enzyme loading for lignocellulose saccharification by 2-4 fold.
