Heavy-oil-degrading Bacteria Isolated by Long-term Enrichment in Alumina Columns Containing Heavy Oil C

Obligate oil-degrading marine bacteria.

Over the past few years, a new and ecophysiologically unusual group of marine hydrocarbon-degrading bacteria - the obligate hydrocarbonoclastic bacteria (OHCB) - has been recognized and shown to play a significant role in the biological removal of petroleum hydrocarbons from polluted marine waters. The introduction of oil or oil constituents into seawater leads to successive blooms of a relativ...

Deep-sea oil plume enriches indigenous oil-degrading bacteria.

The biological effects and expected fate of the vast amount of oil in the Gulf of Mexico from the Deepwater Horizon blowout are unknown owing to the depth and magnitude of this event. Here, we report that the dispersed hydrocarbon plume stimulated deep-sea indigenous γ-Proteobacteria that are closely related to known petroleum degraders. Hydrocarbon-degrading genes coincided with the concentrat...

Heavy oil developments in the Middle East

Oman is currently a particular “hot spot” for investment in a range of EOR techniques to produce heavy oil, but is much less visible in industry statistics than countries such as Canada and Venezuela. Other countries in the Middle East are encouraged by Oman’s success and, with the additional impetus of increasing oil prices, are becoming more active in heavy oil production. For example, Iran a...

Isolation of aroclor1254 degrading bacteria in contaminated soil by transformer oil

ABSTRACT- Aerobic biodegradation is an environmental-friendly biological method that allows micro organisms to remove persistent organic pollutants. Aroclor1254 is a mixed compound containing polychlorinated biphenyls (PCBs) along with persistent organic materials. There is no estimate of Aroclor1254 usage and its release into the environment in Iran. A transformer manufacturing plant in Shiraz...
