Depth-resolved quantification of anaerobic toluene degraders and aquifer microbial community patterns in distinct redox zones of a tar oil contaminant plume
Article Abstract:
The characterization of microbial community distribution across a high-resolution depth profile of a tar oil-impacted aquifer where benzene, toluene, ethylbenzene and xylene (BTEX) degradation has depended mainly on sulfate reduction is described. The results have shown that the distribution of specific aquifer microbiota and degradation processes in contaminated aquifers are tightly coupled, which are used for the assessment of natural attenuation based on intrinsic aquifer microbiota.

Enhanced anaerobic biodegradation of benzene-toluene-ethylbenzene-xylene-ethanol mixtures in bioaugmented aquifer columns
Article Abstract:
The potential of bioaugmentation to enhance the anaerobic degradation of benzene-toluene-ethylbenzene-xylene (BTEX)-ethanol mixtures under methanogenic conditions that are characteristic of sites contaminated by ethanol-blended gasoline was investigated. The results indicate that anaerobic bioaugmentation enhances the natural attenuation of BTEX in groundwater contaminated with ethanol-blended gasoline.

RNA-based stable isotope probing and isolation of anaerobic benzene-degrading bacteria from gasoline-contaminated groundwater
Article Abstract:
RNA-based stable isotope probing (RNA-SIP) technique is used to label and identify anaerobic benzene-degrading organisms from gasoline-contaminated aquifer. The results have revealed that the Azoarcus population is involved in the benzene degradation in the gasoline-contaminated groundwater under denitrifying conditions.
