The role of cell bioaugmentation and gene bioaugmentation in the remediation of co-contaminated soils.
Soils co-contaminated with metals and organics present special problems for remediation. Metal contamination can delay or inhibit microbial degradation of organic pollutants such that for effective in situ biodegradation, bioaugmentation is necessary. We monitored the degradation of 2,4-dichlorophenoxyacetic acid (2,4-D) or 3-chlorobenzoate (3-CB) in two different soils with and without cadmium...
متن کاملA review: advances in microbial remediation of trichloroethylene (TCE).
Research works in the recent past have revealed three major biodegradation processes leading to the degradation of trichloroethylene. Reductive dechlorination is an anaerobic process in which chlorinated ethenes are used as electron acceptors. On the other hand, cometabolism requires oxygen for enzymatic degradation of chlorinated ethenes, which however yields no benefit for the bacteria involv...
متن کاملNew Approaches for Bioaugmentation as a Remediation Technology
Bioaugmentation is commonly employed as a remediation technology. However, numerous studies indicate that introduced microorganisms often do not survive in the environment and thus do not increase contaminant remediation. This review details several new approaches that may increase the persistence and activity of exogenous microorganisms and/or genes following introduction into the environment....
متن کاملPhytoremediation of TCE using Populus
FOREWORD The potential use of plants to remediate contaminated soil and groundwater has recently received a great deal of interest. EPA's Technology Innovation Office (TIO) provided a grant through the National Network for Environmental Management Studies (NNEMS) to assess the status of phytoremediation technologies to clean up shallow groundwater. This report was prepared by a graduate student...
متن کاملResting-State fMRI Using Passband Balanced Steady-State Free Precession
OBJECTIVE Resting-state functional MRI (rsfMRI) has been increasingly used for understanding brain functional architecture. To date, most rsfMRI studies have exploited blood oxygenation level-dependent (BOLD) contrast using gradient-echo (GE) echo planar imaging (EPI), which can suffer from image distortion and signal dropout due to magnetic susceptibility and inherent long echo time. In this s...
