Petroleum microbiology oil while A. borkumensis simutaneously increases synthesis of anionic glucoproteins, which are used to emulsify hydrocarbons in the environment and increase their bioavailability. The presence of crude oil along with appropriate levels of nitrogen and phosphor catalyzes the removal of petroleum either by mechanisms that enhance the efficiency of substrate uptake or by direct biodegradation of aliphatic chains. Two well-known oil spills exemplify large scale marine bioremediation applications: In 1989, the Exxon Valdez ran aground, spilling 41.6 million liters of crude oil, and launching one of the first major bioremediation efforts for an oil spill. Cleanup of Alaskan shorelines relied
NEPCO 140 oil spill NEPCO 140 oil spill The NEPCO 140 Oil Spill took place in 1976 near Clayton, New York when the NEPCO 140 ran aground while traveling inland, spilling an estimated of oil into the Saint Lawrence River. On June 23, 1976, the tugboat "Eileen C" was pushing the NEPCO 140 barge, filled with crude oil, when it ran aground in the American Narrows, off Wellesley Island, in the Thousand Islands region. The Captain had not made a large enough adjustment to his course, when realizing the vessel was off-track in the thick fog.<ref name="Suspension_Revocation/Commandant_Decisions"></ref> Upon running aground, the barge ruptured two
