This book was released on 2011-10-07 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our interest in the microbial biodegradation of xenobiotics has increased many folds in recent years to find out sustainable ways for environmental cleanup. Bioremediation and biotransformation processes harness the naturally occurring ability of microbes to degrade, transform or accumulate a wide range of organic pollutants. Major methodological breakthroughs in recent years through detailed genomic, metagenomic, proteomic, bioinformatic and other high-throughput analyses of environmentally relevant microorganisms have provided us unprecedented insights into key biodegradative pathways and the ability of organisms to adapt to changing environmental conditions. The degradation of a wide spectrum of organic pollutants and wastes discharged into the environment by anthropogenic activities is an emerging need today to promote sustainable development of our society with low environmental impact. Microbial processes play a major role in the removal of recalcitrant compounds taking advantage of the astonishing catabolic versatility of microorganisms to degrade or transform such compounds. New breakthroughs in sequencing, genomics, proteomics, bioinformatics and imaging are generating vital information which opens a new era providing new insights of metabolic and regulatory networks, as well as clues to the evolution of degradation pathways and to the molecular adaptation strategies to changing environmental conditions. Functional genomic and metagenomic approaches are increasing our understanding of the relative importance of different pathways and regulatory networks to carbon flux in particular environments and for particular compounds. New approaches will certainly accelerate the development of bioremediation technologies and biotransformation processes in coming years for natural attenuation of contaminated environments

This book was released on 2001 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: The extensive use of aromatic hydrocarbons in industrial processes, coupled with inadequate management strategies, has let to the widespread introduction of these compounds into our environment (89). Many of these xenobiotics are potentially toxic and this feature is often compounded by an inherent recalcitrance to degradation by physical processes. However, due to the existence of naturally occurring aromatic hydrocarbons in the environment, bacteria have evolved a wide array of enzymes and degradative pathways with the potential to transform these xenobiotics into harmless metabolic by-products. A significant factor in this degradative evolution has been the location of catabolic cassettes on promiscuous plasmids, allowing microorganisms to broaden their catabolic substrate range (85). Degradative pathways have also been shown to be chromosomally located (62). It is hoped that research into the aromatic hydrocarbon degradation pathways of various microorganisms will provide us with the necessary tools to establish feasible xenobiotic bioremediation strategies in the near future. One aromatic compound, styrene, whose microbial catabolism has been intensely investigated, is discussed here. Styrene, the simplest of all alkenylbenzenes, (Table1, Figure 1), is extensively used both as a starting material for synthetic polymers and as a solvent for polymer processing, and is consequently found in a variety of industrial effluents. It lacks true xenobiotic status however, as it is produced naturally by the degradation of cinnamic acid in decaying plant material and by fungal metabolic processes (86,93). Airborne, gaseous emissions are of particular concern due to malodorous properties of the compound and its potential toxic and carcinogenic effects. Personnel involved in the manufacture of glass-reinforced plastics and large-scale boat building are at greatest risk of exposure to styrene.

Download or read book Handbook on Biodegradation and Biological Treatment of Hazardous Organic Compounds written by M.H. van Agteren and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: The introduction of synthetic organic chemicals into the environment during the last few decades has given rise to major concern about the ecotoxicological effects and ultimate fate of these compounds. The pollutants that are considered to be most hazardous because of their intrinsic toxicity, high exposure level, or recalcitrant behavior in the environment have been placed on blacklists and other policy priority lists. The fate of synthetic compounds that enter the environment is mainly determined by their rate of biodegradation, which therefore also has a major effect on the degree of bioaccumulation and the risk of ecotoxicological effects. The degree and rate of biodegradation is also of critical importance for the feasibility of biological techniques to clean up contaminated sites and waste streams. The biodegradation of xenobiotics has thus been the subject of numerous studies, which resulted in thousands of publications in scientific journals, books, and conference proceedings. These studies led to a deeper understanding of the diversity of biodegradation processes. As a result, it has become possible to enhance the rate of degradation of recalcitrant pollutants during biological treatment and to design completely new treatment processes. At present, much work is being done to expand the range of pollutants to which biodegradation can be applied, and to make treatment techniques less expensive and better applicable for waste streams which are difficult to handle.
Download or read book Bioremediation and Sustainability written by Romeela Mohee and published by John Wiley & Sons. This book was released on 2012-03-27 with total page 439 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioremediation and Sustainability is an up-to-date and comprehensive treatment of research and applications for some of the most important low-cost, "green," emerging technologies in chemical and environmental engineering Sustainable development requires the development and promotion of environmental management and a constant search for green technologies to treat a wide range of aquatic and terrestrial habitats contaminated by increasing anthropogenic activities with the main sources of contaminants being the chemical industries. Bioremediation is a technique that uses living organisms in order to degrade or transform contaminants into their less toxic forms. It is based on the existence of microorganisms with the capacity to attack the compounds on the enzymatic level. Bioremediation is an increasingly popular low-cost alternative to conventional methods for treating wastes and contaminated media with the possibility to degrade these contaminants using natural microbial activity mediated by different consortia of microbes. Over the last few years, the scientific literature has revealed the progressive emergence of various bioremediation techniques. Bioremediation and Sustainability presents an up-to-date and comprehensive collection of chapters prepared in bioremediation technology research and applications. The strategies covered in this volume can be applied in situ or ex situ, depending on the site in which they will be applied. In situ is the treatment done in the site of the contamination, and ex situ involves the removal of soil or water to subsequent treatment. There is a wide variety of techniques that have been developed in the past and are covered in this volume, such as natural attenuation, bioaugmentation, biostimulation, biosorption, composting, phytoremediation, rhizoremediation, and bioleaching.
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.
