Degradation of polynuclear aromatic hydrocarbons by Sphingomonas paucimobilis
Article Abstract:
Sphingomonas paucimobilis, strain EPA 505 has the ability to degrade a number of tetracyclic and pentacyclic four- and five-ring polynuclear aromatic hydrocarbons (PAHs) with varied molecular size, shape and chemical structure. These PAHs include chrysene, pyrene, benz(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene and dibenz(a,h)anthracene. S. paucimobilis is a soil bacterium that can utilize fluoranthene as the only source of carbon and energy for growth.

Constituents of an organic wood preservative that inhibit the fluoranthene-degrading activity of Sphingomonas paucimobilis strain EPA505
Article Abstract:
Solvent extraction of organic wood preservative, creosote, yielded three classes of creosote contituents namely polycyclic aromatic hydrocarbons (PAHs), phenolics and heterocyclics, that inhibit the fluoranthene-degrading activity of Sphingomonas paucimobilis strain EPA505. The integration of a pretreatment step prior to inoculation of strain EPA505 could help increase the effectiveness of strain EPA505 to degrade fluoranthene.

Isomer-specific determination and toxic evaluation of polychlorinated biphenyls, polychlorinated/brominated dibenzo-p-dioxins and dibenzofurans, polybrominated biphenyl ethers, and extractable organic halogen in carp from the Buffalo River, New York
Article Abstract:
Carp from New York's Buffalo River were analyzed to determine the concentrations of polychlorinated biphenyls, polychlorinated/brominated dibenzo-p-dioxins and dibenzofurans, polybrominated biphenyl ethers and extractable organic halogen. The results showed that carp from the Buffalo River had very high concentrations of polychlorinated biphenyl isomers, thus making them unfit for human consumption.
