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.

Download or read book Lignocellulose Biotechnology written by Ramesh Chander Kuhad and published by I. K. International Pvt Ltd. This book was released on 2007 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: The agricultural and forestry processing wastes (lignocellulosics) are an important material resource and energy source. However, if untreated they can pose a danger to the environment and potentially valuable resources. Microorganisms contribute significantly to solving the problem of biomass degradation, its recycling and conservation. In the recent years, an increasing interest shown by the textile, food, feed & pulp, and paper industries in the microbial and enzymatic processes has triggered in-depth studies of lignocellulolytic microorganisms and their enzymes. Moreover, the advent of recombinant DNA technology in the late 1970s further paved the way for developing technologies based on lignocellulolytic microbes and enzymes. Lignocellulose Biotechnology presents a comprehensive review of the research directed towards environmentally friendly agricultural and forest by-products. The book comprises 22 chapters, divided in four sections. It deals with a wide range of topics including biodiversity of lignocellulose degrading microorganisms and their enzymes, molecular biology of biodegradation of lignin, characterization of lignocellulolytic enzymes, bioconversion of plant biomass to produce enzymes, animal feed, bioethanol and industrial applications of lignocellulolytic enzymes. The chapters dealing with industrial applications also address current biotechnological approaches in lignocellulose bioconversion to value added products. This book is essential for students, researchers, scientists, and engineers working in the fields of environmental microbiology, environmental biotechnology, life sciences, waste management, and biomaterials.

This book was released on 2012-12-06 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume comprises the papers presented at the Session on Wood Products Pathology during the 2nd International Congress on Plant Pathology on 10th - 12th September 1973 in Minneapolis/USA. The topics were dealt with under four heads, viz. Interaction of Microorganisms during Wood Decay, Bacterial Degradation of Wood, Decay of Resistant Wood and Enzymatic Mechanisms of Deterioration Process, followed by a Discussion Session on Extension: an obli gation of all Wood Products Pathologists •. Thanks to the cooperation of the authors all the papers could be compiled in this volume. The conference gave an unique possibility to discuss in depth the principles of wood decay by microorganisms from the various angles. The chapters give detailed information on the current progress and problems in wood products pathology. They are therefore collected together in this volume so that people interested in this field will have immediate access to the material and ideas presented. The topic of this Session, the degradation of wood by fungi and bacteria, has become more and more important during the last years. Wood is the only renewable natural resource and raw material of man so that it must be preserved against unwanted deterioration. On the other hand, its natural decomposition does not lead to any harmful products but only to carbondioxide and water. Both aspects have been dealt with in this volume.

Download or read book The Structure Biosynthesis and Degradation of Wood written by F. Loewus and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest trees constitute one of the major resources of the world and their utilization, either for structural purposes or for the materials which they yield, dates back to antiquity. Over the centuries, the exploitation of this resource has become progressively more sophisticated, and, in many parts of the world has led to the development of highly complex forest-based industries. The research and development work which led to these industrial uses fostered the formation of numerous technical societies and associations, which, through their meetings and publi cations, have facilitated communication and the exchange of ideas. Over the years, there have been numerous symposia devoted to wood and the many facets of its properties and utilization. However, rarely has the emphasis in such symposia been placed upon the living tree and the changes which it undergoes in relation to its ultimate utilization. Hence the Phytochemical Society of North America arranged the symposium, "The Structure, Biosynthesis, and Degradation of Wood", held at the University of British Columbia in August, 1976. the contributions to which form the basis of the present volume.

Download or read book Biology of Composts written by Mukesh K. Meghvansi and published by Springer Nature. This book was released on 2020-04-09 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights the latest findings on fundamental aspects of composting, the interaction of various microorganisms, and the underlying mechanisms. In addition to addressing modern tools and techniques used for composting research, it provides an overview of potential composting applications in both agriculture and environmental reclamation. Composting is the process of organic waste decomposition, mediated by microorganisms. The end-product is called ‘compost’ and can be used as a supplement to improve soil fertility. As the municipal waste generated in most developing countries contains a substantial amount of organic matter suitable for composting, this technology offers a win-win opportunity for stakeholders in terms of disposing of organic waste and providing organic fertilizers for agriculture. In addition, using compost reduces the dependency on harmful chemical fertilizers, and represents a sustainable and environmentally friendly alternative.
