A method is described for extracting the petroleum from petroleum-bearing ̄uid inclusions hosted in the diagenetic cements of sedimentary rocks, whilst minimising contamination from petroleum in the pore space. A clean-up technique, involving the addition of extraction standards to the rock prior to analysis, has been developed that allows increased con®dence that the hydrocarbons extracted are...

We report here the 4,856,096-bp draft genome sequence of hydrocarbon-degrading Cronobacter sp. strain DJ34 isolated from crude oil-containing sludge from the Duliajan oil fields, India. DJ34 contains genes that mediate hydrocarbon degradation, metal resistance, and biosurfactant production. This is the first report of the genome sequence of Cronobacter sp. inhabiting an oil-contaminated environ...

In this study we tested the use of seabird blood as a bioindicator of polycyclic aromatic hydrocarbon (PAH) pollution in the marine environment. Blood cells of breeding yellow-legged gulls (Larus michahellis) were able to track spatial and temporal changes consistent with the massive oil pollution pulse that resulted from the Prestige oil spill. Thus, in 2004, blood samples from yellow-legged g...
