Enrichment, isolation, and phylogenetic identification of polycyclic aromatic hydrocarbon-degrading bacteria from Elizabeth River sediments

Article Abstract:

The classical selective enrichment and molecular analyses are used for examining the diversity of indigenous bacteria in sediments from many sites in the Elizabeth River (Virginia) able to degrade multiple polycyclic aromatic hydrocarbons (PAHs). The large collection of diverse PAH-degrading strains has provided a good resource for analyzing the mechanisms of PAH degradation and bioremediation.

Subtle difference between benzene and toluene dioxygenases of Pseudomonas putida

Article Abstract:

The differences between benzene and toluene dioxygenases from Pseudomonas putida that is necessary for conversion of the substrate preference of benzene dioxygenase from benzene to alkyl-substituted aromatic hydrocarbons, such as toluene and ethylbenzene, are investigated. The activities of benzene, toluene and ethylbenzene are examined by an oxygen electrode assay.
