  1. 1. Comparison of in-situ bioremediation of soil contaminated with chlorinated hydrocarbons

    University essay from Högskolan i Halmstad

    Author : Tianyu Qin; [2020]
    Keywords : bioremediation; biostimulation; bioaugmentation; product; chlorinated hydrocarbon;

    Abstract : In recent years, due to the continuous development of machinery, electronics, leather, chemical companies and dry-cleaning industry, more and more chlorinated hydrocarbons accumulate in the soil, causing serious harm to the environment. The accumulation of chlorinated hydrocarbons and the teratogenic, carcinogenic, and mutagenic hazards seriously threaten human health. READ MORE

  3. 2. Evaluation of stimulated reductivedechlorination in situ of chlorinatedsolvents at a site in Huddinge : using principal component analysis, partialleast square regression and degradation

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Karin Ljungberg; [2018]
    Keywords : Reductive dechlorination; DNAPL; stimulated bioremediation; chlorinated solvents; Reduktiv deklorering; DNAPLS; stimulerad biologisk behandling; klorerade lösningsmedel;

    Abstract : The method of using stimulated reductive dechlorination when remediating sites contaminated with chlorinated solvents is not unusual, but not many studies have been done on the overall process outside of a controlled environment. In order to investigate the process, principal component analysis (PCA) and partial least square (PLS) regression was used to identify the most important parameters for the degradation of the chlorinated solvents.

  4. 3. Identification and Characterization of Gene Functions Involved in Recalcitrant Compound Degradation Using Metagenomic Data

    University essay from Institutionen för naturvetenskap, miljö och teknik

    Author : Tino Lawson; [2012]
    Keywords : recalcitrant; dienelactone hydrolase; metagenomics;

    Abstract : With the environmental problems caused by man-induced pollution by persistent toxic compounds, the importance of finding remediation solutions is immense. As an emerging field, microbial environmental biotechnology may provide the tools to achieve novel solutions. READ MORE

  5. 4. The potential of biodegradation on 1, 1, 1-trichloro-2, 2-bis (p-chlorophenyl) ethane, based upon co-metabolism of indigenous bacteria

    University essay from Akademin för hållbar samhälls- och teknikutveckling

    Author : Aniko Hellebrandt; [2010]
    Keywords : soil contamination; DDT; Ostracodtoxkit FTM; biodegradation; bioreactors; talaj szennyezés; DDT; Ostracodtoxkit FTM; biodegradáció; bioreaktorok;

    Abstract : The purpose of this project is to evaluate the potential of a bioreactor system to degrade DDT based upon co-metabolism of indigenous bacteria. The study was performed with soil samples spiked with four different concentrations of DDT. READ MORE

  6. 5. Degradation of aged creosote and diesel contaminated soils by phytoremediation or biostimulation (nutrients)

    University essay from SLU/Dept. of Soil Sciences

    Author : Nghia Nguyen Khoi; [2007]
    Keywords : creosote; diesel fuel; PAHs; benzo fluoranthene; benzo pyrene; phenathrene; bioremediation; phytoremediation; salix clones;

    Abstract : Aged creosote and diesel fuel polluted soil was collected from Resecentrum, Uppsala (deposited at Hovgården). The aims of this study were: 1) to compare the growth and degradation of PAHs and diesel by five Salix clones and 2) to study the effect of nutrients on biodegradation of PAHs and diesel. READ MORE
