This book was released on 2002 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pesticides have played a significant role in increasing food production, and in view of growing worldwide food demand. Nevertheless; some of them have been classified as persistent toxic chemicals. This has resulted in serious concern about environmental contamination. Once a pesticide or toxic chemical find its way in the environment, a major part of it comes in contact with soil. There are several possible sources of pesticide contamination; at manufacturing, storage, or user sites. The most serious examples of pesticide contamination are typically the result of poor production and waste management practices of pesticide manufacturing, formulation, and application facilities. Improper storage, handling, and also have resulted in pesticide contamination at these sites and at landfills. Today, many remediation technologies are used to remove the pesticides from the soil. One of the soil treatment methods is enhanced biodegradation. Bioremediation of the soil has often proven to be a cheap solution for contaminated soil problem. This research was conducted to investigate the effectiveness of biologically produced surfactants (biosurfactants) on the biodegradation of pesticide-contaminated soil and evaluate the potential for biosurfactant-enhanced bioavailability of pesticide in soil. In order to determine the effectiveness of biosurfactants on pesticides, sophorolipid and rhamnolipid type biosurfactants were used. These biosurfactants were chosen since they are well characterized and their stimulating effect on the biodegradation of hydrophobic substrates was described in the literature. In this study, endosulfan and trifluralin were selected as pesticides. The study was performed in two stages in laboratory conditions. In the first part of the experiment, degradation of endosulfan-contaminated soil was studied by the presence of sophorolipid and in the second part of the experiment; rhamnolipid (JBR 425) was used on the removal of trifluralin-contaminated soil. Throughout the experiment, three different concentrations of sophorolipid and rhamnolipid were applied to soil which, are 0.98, 9.75 and 195 ppm for sophorolipid and 1.6, 100 and 1000 ppm for rhamnolipid. The effectiveness of synthetic or microbial surfactants on biodegradation of chemicals has been investigated by many researchers. However, studies about the biosurfactant enhanced soil remediation for the pesticide contaminants are limited. Besides that, the outcome of surfactant applications has been highly system-specific, conflicting results reported in the literature. Therefore, despite the general trends outlined in literature, the effect of biosurfactants on the biodegradation of organic compounds is poorly understood. Opposed effects are frequently observed. This study is the first M.Sc. thesis study about the use of biosurfactant enhanced bioremediation of pesticides in Turkey. The results from first part of our study obtained from sophorolipid, were not satisfactory since the degradation patterns for endosulfan were not affected by the presence of sophorolipid. According to the second experiment results, removal of trifluralin ranged from 24-35 %, with the increase in rhamnolipid concentrations. Addition of rhamnolipid (JBR 425) into the soil was found to increase the degradation rate of trifluralin by 13 % as compared to the control soil column. Additional time would probably increase the rate of degradation and bioavailability, as a result of providing the adaptation of microorganisms in contaminated soil media and formation of more bioavailable metabolites.

This book was released on 2018-11-02 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comprehensive collection of various in situ and ex-situ soil remediation regimes that employ natural or genetically modified microbes, plants, and animals for the biodegradation of toxic compounds or hazardous waste into simpler non-toxic products. These techniques are demonstrated to be functionally effective in connection with physical, chemical, and biological strategies. Soil and water contamination through heavy metals, hydrocarbons and radioactive wastes is of global concern, as these factors have cumulative effects on the environment and human health through food-chain contamination. The book discusses the utilization of algae, plants, plant-associated bacteria, fungi (endophytic or rhizospheric) and certain lower animals for the sustainable bioremediation of organic and inorganic pollutants. In addition, it explores a number of more recent techniques like biochar and biofilms for carbon sequestration, soil conditioning and remediation, and water remediation. It highlights a number of recent advances in nanobioremediation, an emerging technology based on biosynthetic nanoparticles. Lastly, it presents illustrative case studies and highlights the successful treatment of polluted soils by means of these strategies.

Download or read book Biosurfactants written by Ramkrishna Sen and published by Springer Science & Business Media. This book was released on 2010-12-31 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: The microbial world has given us many surprises including microbes that grow under extremely harsh conditions (122C at 40 MPa), novel metabolisms such as the uranium and perchlorate reduction, and novel chemicals that can be used to control diseases. We continually face new and difficult problems such as the need to transition to more carbon-neutral energy sources and to find eco-friendly chemicals and to find new drugs to treat disease. Will it be possible to tap into the seemingly limitless potential of microbial activity to solve our current and future problems?The answer to this question is probably yes. We are already looking to the microbial world to provide new energy sources, green chemicals to replace those made from petroleum, and new drugs to fight disease. To help us along these paths, we are deciphering how microorganisms interact with each other. We know that microbial populations interact and communicate with each other. The language that microbes use is chemical where small molecules are exchanged among different microbial cells. Sometimes, these chemicals suppress activities of competitors and could be used as antibiotics or may have other therapeutic uses. Other times, the chemicals stimulate complex responses in microbial populations such as fruiting body or biofilm formation. By understanding the conversation that microbes are having among themselves, e. g.

Download or read book Bioaugmentation for the Remediation of Pesticide contaminated Soil with Microorganisms Directly Enriched in Soil Or Compost written by Sang-Jun Kim and published by . This book was released on 2003 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: EPTC (s-ethyl-N, N'-dipropylthiocarbamate) and atrazine (2-chloro-4-ethylamino-6-isopropylamino-1,3,5-triazine) are commonly used herbicides. Atrazine, especially, can be found in soils and waters at unacceptable concentrations. Developing an effective inoculum to bioaugment degradation of EPTC and atrazine in contaminated environments is required for bioremediation of such sites. Microorganisms capable of EPTC or atrazine degradation were directly enriched in soils (hereafter called ACTIVATED soils). The most probable number method revealed that the number of EPTC-degraders in a Brookston soil increased by about 3 logs of magnitude after a single treatment with EPTC at a rate of 20 mg/kg soil. In a Wooster soil, microorganisms utilizing atrazine as their sole carbon or nitrogen source increased by 3 logs and 1 log of magnitude, respectively, after three treatments of atrazine at a rate of 4 mg/kg soil. EPTC or atrazine degradation in these ACTIVATED soils was greatly accelerated after the first treatment, and degradation activity was not inhibited at initial concentrations up to 2000 mg EPTC/kg and 400 mg atrazine/kg soil, respectively. Inoculation of EPTC (20 mg/kg)- or atrazine (4 mg/kg)-contaminated soils with ACTIVATED soil, at rates ranging from 0.05 to 5% (w/w), resulted in significantly (p
