This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the primary impediments to the implementation of bioremediation is uncertainty about success in the field. Soils and microbial populations are heterogeneous and it is difficult to extrapolate biodegradation rates from small samples to field scale. While biodegradation rates can be estimated from microcosm studies, in situ methods offer a more meaningful gauge of resident microbial activity. One method used to estimate biodegradation rates in the field is the newly developed Push-Pull technique. While this technique can be conducted on site, it is normally not possible to use target pollutants as the reactive substrates. Consequently, alternative, benign reactive tracers must be used. Ideally, these alternative, reactive tracers interrogate the same enzyme systems that are responsible for the biodegradation of the target pollutant. The objective of this study was to develop a reactive tracer system that could be used to assess toluene-dependent trichloroethylene (TCE) degradation. Our approach has been to determine whether a series of pure strains of toluene-oxidizing bacteria (Burkholderia cepacia G4, Pseudomonas putida F1, Pseudomonas putida mt2, Pseudomonas mendocina KR1), each with different toluene-oxidizing enzymes systems, are capable of cometabolically oxidizing a series of eleven potential alternative substrates. These substrates include simple alkenes, alkanes, and cyclic alkanes. The kinetics (Ks and Vmax) of the biotransformation of these compounds have been determined. While oxidation products were observed for a number of these substrates in connection with one or more of the test organisms, isobutylene was co-oxidized by all test organisms. Oxidation of isobutylene by each organism yielded kinetics constants comparable to the corresponding kinetics of TCE degradation. The enzyme system expressed by Burkholderia cepacia G4 catalyzed the epoxidation of isobutylene while the remaining enzyme systems catalyzed allylic alcohol formation. Isobutylene.

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.

DAVISON Oak Ridge National Laboratory MARK FINKELSTEIN National Renewable Energy Laboratory CHARLES E. WYMAN Oak Ridge National Laboratory The Eighteenth Symposium on Biotechnology for Fuels and Chemi cals continues to provide a forum for the presentation of research results and the exchange of ideas on advances in biotechnology for the produc tion of fuels and chemicals. Although the emphasis is on utilization of renewable resources, the scope of the Symposium is broader than this and includes bioconversion of fossil fuels and syngas and the new area of conversions in nonaqueous environments; these areas were discussed in Session 5 and in a Special Topic Discussion Group at the Symposium. In addition, recent developments in bioremediation were well represented in Session 6 and in the poster session. The Symposium involved both the development of new biological agents (such as enzymes or microbes) to carry out targeted conversions as well as bioprocess development. The first area covered improvements in enzymes as well as fundamental insights into substrate-enzyme inter actions and photosynthesis. The latter area focused on converting one material into another using biological agents through combinations of chemical engineering, biological sciences, and fermentation technology. This area also refers to an overall processing involving at least one bio logically catalyzed step in combination with other physical and/ or chemi cal processing operations. Agricultural crops, such as corn and corn fiber as well as woody biomass and lignocellulosic wastes, are emphasized for process feedstocks and their pretreatment investigated.

This book was released on 2013-03-14 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years public awareness of the long term toxic affects heavy metal ions in waters and wastewaters has increased significantly. Environmental agencies have been imposing more and more stringent discharge limits on industries involved in processes using metal ions. Numerous industries produce aqueous effluents con taining metal ions and particularly copper and cadmium. Copper sulfate is used on a large scale in the electroplating industries. In addition, copper salts are used as fungicides, timber preservatives, insecticides, paint corrosion inhibitors and in dyestuffs. Cadmium is used in the manufacture of nickel-cadmium batteries, as a corrosion inhibitor and control rods in the nuclear industry. The European Com munity has listed cadmium as one of the most dangerous metal due to its toxicity, persistence and bioaccumulation in List 1 of its Directive 76/464/EEC. Therefore, it is important that methods for the removal of these metal ions are found and that the mechanism of removal is characterized and understood. A number of adsorb ents have been identified which are capable of removing copper (Panday et aI. , 1985; Ho et aI. , 1996; Low and Lee, 1987; Low et aI. , 1993; Quek et aI. , 1998) and cadmium (Battacharya and Venkobachar, 1984; Namasivayam and Ranganathan, 1995; Periasamy and Namasivayam, 1994) from aqueous solutions. Sorption kin etic models have been proposed for some systems.
