Recently, the development and optimisation of a flow injection analysis (FIA) operated bacterial biosensor based on the aerobic catabolism of Pseudomonas putida ML2 was reported in the literature (Layon Y.H. e al. 2004a; Lanyon Y.H. e al. 2004b). Adapted from these reports, it was investigated whether operating parameters and procedures of the benzene biosensor could be directly applied to a ne...

BACKGROUND Hazardous air pollutant exposures are common in urban areas contributing to increased risk of cancer and other adverse health outcomes. While recent analyses indicate that New York City residents experience significantly higher cancer risks attributable to hazardous air pollutant exposures than the United States as a whole, limited data exist to assess intra-urban variability in air ...

Determination of stable carbon (613C) isotope systematics for alkylphenols and light aromatic hydrocarbons (BTEX) in petroleum formation waters and co-produced oils Gordon D. Love, Andrew C. Aplin*, Stephen R. Larter, Gillian Taylor School of Civil Engineering and Geosciences, University of Newcastle upon Tyne, Newcastle upon Tyne NE1 7RU, UK

this paper investigates the importance of considering biomass growth and decay for predicting a field scale microbial degradation of btex plume in an unconfined aquifer system in the pump station area of tehran oil refinery (tor), iran. a two-dimensional finite volume model has been presented to predict multi-species reactive transport incorporating physical, chemical and biological processes i...

The development of slow-release chemical oxidants for sub-surface remediation is a relatively new technology. Our objective was to develop slow-release persulfate-paraffin candles to treat BTEX-contaminated groundwater. Laboratory-scale candles were prepared by heating and mixing Na(2)S(2)O(8) with paraffin in a 2.25 to 1 ratio (w/w), and then pouring the heated mixture into circular molds that...

In this study, the concentrations of five volatile organic compounds (VOCs), including BTEX and methyl tertiary-butyl ether (MTBE), were investigated in five different traffic tunnels (including Liangshan, Yueguangshan, Zoying, Guogang and Zhongliao tunnels) in southern Taiwan. Results showed that Guogang Tunnel was the most polluted with the highest average levels of both MTBE and BTEX while e...

Pseudoxanthomonas spadix BD-a59, able to metabolize all six BTEX (benzene, toluene, ethylbenzene, and o-, m-, and p-xylene) compounds, was isolated from gasoline-contaminated sediment. Here, we report the complete 3.45-Mb genome sequence and annotation of strain BD-a59. These advance the understanding of strain BD-a59's genomic properties and pollutant metabolic versatility.
