TLDR
In this article, petroleum has been dredged from an active hydrothermal mound area in the southern rift of Guaymas Basin, Gulf of California, and the organic matter is composed of gasoline-range aliphatic and aromatic hydrocarbons and predominantly residual polar asphaltic material.Abstract:
Petroleum has been dredged from an active hydrothermal mound area in the southern rift of Guaymas Basin, Gulf of California. This organic matter is composed of gasoline-range aliphatic and aromatic hydrocarbons and predominantly residual polar asphaltic material. The aliphatic hydrocarbons of two bitumen samples have very different boiling range and composition. Both samples contain polynuclear aromatic hydrocarbons and olefins, which indicate formation at pyrolytic temperatures. The overall compositional data indicate an origin from biological detritus by thermal alteration and rapid quenching by hydrothermal removal, followed by condensation at the seabed.read more

Anaerobic oxidation of hydrocarbons in crude oil by new types of sulphate-reducing bacteria
P. Rueter,Ralf Rabus,Heinz Wilkes,F. Aeckersberg,Fred A. Rainey,Holger W. Jannasch,Friedrich Widdel +6 more
TL;DR: In this paper, a mesophilic sulphate-reducing enrichment culture is shown to oxidize alkylbenzenes in oil. But the authors did not identify the actual electron donors and carbon sources.

TL;DR: The qualitative PAH pattern is remarkably constant for most of the locations studied, and the quantitative PAH abundance increases with proximity to urban centers as discussed by the authors, consistent with anthropogenic combustion's being the major source of these compounds.
