In the past decade, Deepwater Horizon oil spill triggered a spike in investigatory effort on effects of crude chemicals, most notably polycyclic aromatic hydrocarbons (PAHs), marine organisms and ecosystems. Oysters, susceptible to both waterborne sediment-bound contaminants due their filter-feeding sessile nature, have become great interest among scientists as bioindicator model organism for r...

Sphingobium sp. strain C100 was isolated from a polycyclic aromatic hydrocarbon (PAH)-degrading consortium from the deep-sea sediment of the Arctic Ocean. It can degrade two- to four-ring PAHs at 25°C. Here we present the draft genome sequence of this strain, which is 4,776,810 bp with a G+C content of 63.9%.

The single-wing extension of the bowl-shaped tribenzotriquinacene (TBTQ) framework with polycondensed aromatic hydrocarbon units has been reported. In the course of a Scholl reaction, one of the three-dimensional bays of the TBTQ core has been bridged by a PAH unit to generate a seven-membered ring within the merged TBTQ-(hexa-peri-hexabenzocoronene) scaffold.

The bacterial strain TR3.2, representing a novel deeply branching lineage within the Gammaproteobacteria, was isolated and its genome sequenced. This isolate is the first cultivated representative of the previously described "Pyrene Group 2" (PG2) and represents a variety of environmental sequences primarily associated with petrochemical contamination and aromatic hydrocarbon degradation.

Ultrasensitive photoelectrochemical immunoassay of polycyclic aromatic hydrocarbon (PAH) is proposed using an antibody-modified nanostructured TiO(2) electrode combined with bifunctional gold nanoparticles modified with the PAH antigen and horseradish peroxidase (HRP). The HRP-catalyzed reaction prompts the electron transfer between the electrode and electrolyte causing an excellent photocataly...

The effect of testosterone as the sole carbon source on protein expression was analyzed in Comamonas testosteroni. Testosterone simultaneously induced the expression of steroid- and aromatic hydrocarbon-catabolizing enzymes and repressed one amino acid-degrading enzyme. It is suggested that steroids play a regulative role in catabolic enzyme synthesis during adaptive growth of C. testosteroni.
