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.

Available in PDF, EPUB and Kindle. Book excerpt: This volume reviews basic research into the biochemistry and genetics of lignocellulose biodegradation; the breakdown of cellulose containing products utilizing microorganisms. This topic has received much attention of late because of possibilities for the biotechnology industry and because it is hoped that advances in the field will make a contribution to the energy crisis by utilizing biomass. However, there remains a good deal of basic research still to be done before full exploitation can be achieved.

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 Ecology of Saprotrophic Basidiomycetes written by Lynne Boddy and published by Elsevier. This book was released on 2007-12-29 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: The breadth and depth of understanding of many areas concerning basidiomycetes has increased dramatically since the premier publication of Frankland et al., Decomposer Basidiomycetes: their Biology and Ecology. New vistas have opened up with the advent of powerful computing, modeling and molecular approaches helping to greatly increase the general understanding of the ecology of basidiomycetes. This is tantamount to understanding the role of fungi in natural ecosystems because they are major agents of decomposition and nutrient cycling. These remarkable advances have been incorporated into this volume that discusses all aspects of saprotrophic basidiomycete ecology.

Download or read book Biodegradation written by W.B. Betts and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two major problems encountered as we approach a new century are the availability of resources for chemicals and energy, and environmental pollution. This book highlights the importance of biotransformation as a solution to these problems and considers traditionally separate areas as one interdependent discipline, in terms of the underlying mechanistic biochemistry and the research techniques employed. The provision of resources has largely centred around non-renewable materials, especially oil. Diminishing reserves of these, together with uncertainties of supply and cost have stimulated great interest in renewable resources. These are largely lignocellulosic materials (e.g. wood and straw) which are available through natural biomass turnover, farming and forestry and from wastes generated by industrial processes. An excellent example is that of kraft lignin, a by-product of pulp and paper production, amounting to 60 million tonnes per annum and which is largely wasted by burning or landfilling. This aromatic polymer has enormous potential as a feedstock to the chemical industry. Environmental pollution is no longer accepted as inevitable for a technological society. Over the past decade there has been a tremendous increase in awareness of the effects of pollution and public pressure has influenced both industry and government. However, to be realistic, it is not possible to replace all processes generating polluting wastes with clean alternatives. Instead, treatments of pollution, both at source and after an incident, are alternatives in many instances and a great deal of emphasis is currently being placed on these.

Download or read book The Rumen Microbial Ecosystem written by P.N. Hobson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 741 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Preface to the first edition of this book explained the reasons for the publication of a comprehensive text on the rumen and rumen microbes in 1988. The microbes of the ruminant's forestomach and those in related organs in other animals and birds provide the means by which herbivorous animals can digest and obtain nutriment from vegetation. In turn, humans have relied, and still do rely, on herbivores for much of their food, clothing and motive power. Herbivores also form the food of carnivorous animals and birds in the wild. The importance of the rumen microorganisms is thus apparent. But, while a knowledge of rumen organisms is not strictly neces sary for the normal, practical feeding of farm animals, in recent years there has been much more emphasis on increasing the productivity of domesti cated animals and in rearing farm animals on unusual feedstuffs. Here, a knowledge of the reactions of the rumen flora, and the limits to these reactions, can be invaluable. In addition, anaerobic rumen-type microor ganisms are found in the intestines of omnivores, including humans, and can be implicated in diseases of humans and animals. They are also found in soils and natural waters, where they playa part in causing pollution and also in reducing it, while the same organisms confined in artificial systems are essential for the purification of sewage and other polluting and toxic wastes.
