Berkeley's Answer to Gulf Oil Spill Mystery

Biologists at UC Berkeley discovered a previously unknown type of oil-eating bacteria while studying this summer's Deepwater Horizon oil spill in the Gulf of Mexico. Their findings may help answer one of the mysteries of the spill: Where did all the oil go? By some account all of the oil has vanished, and it's now impossible to detect in Gulf waters. That seems impossible when you think about the nearly five million barrels of oil that spilled. The Berkeley researchers credit in part the new and still unclassified species for degrading the oil much faster than anyone anticipated. Ever since BP's catastrophic equipment failure, BP deployed an unprecedented quantity of commercial oil dispersant near the well head. The tiny deep-water micro-organisms called gamma-proteobacteria have been gobbling down the oil. The little guys turned the 22-mile long toxic plume "undetectable," according to Terry C. Hazen, the chief microbiologist at the Department of Energy's Lawrence Berkeley National Laboratory. More>
