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.

Los hidrocarburos aromáticos monocíclicos: benceno, tolueno, etilbenceno y xileno (BTEX), presentes en crudo refinados de petróleo, hacen parte los compuestos con más impacto el medio ambiente la salud humana, debido a su naturaleza cancerígena, mutagénica altamente tóxica. Esta investigación tuvo como objetivo obtener caracterizar bacterias capaces degradar tolueno. Se realizaron tres muestreo...

Plasma polymerized (PP) thin films deposited in a soft or intermediate plasma discharge from hexamethyldisiloxane (HMDSO) were developed as sensors for the detection of volatile organic compound (VOC) vapors. Energy dispersive X-ray spectroscopy (EDX) and reflectometry (XRR) performed to determine organosilicon films’ elemental composition density. Spectroscopic ellipsometry measurements carrie...

The objective of this study was to evaluate and obtain mathematical models, using the experimental design methodology, capable predicting contamination benzene, toluene, ethylbenzene xylenes (BTEX) in cases oil spillage at sea, acute toxicity soluble petroleum fraction (FSA). factorial planning developed describe concentration each compound according variables: °API, contact time oil/seawater a...

In this study the full-scale operation of soil flushing with air sparging to improve the removal efficiency of petroleum at depths of less than 7 m at a military site in Korea was evaluated. The target area was polluted by multiple gasoline and diesel fuel sources. The soil was composed of heterogeneous layers of granules, sand, silt and clay. The operation factors were systemically assessed us...
