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
Odyssey (tanker) "Exxon Valdez". Odyssey, built in 1971, was a 65,000-ton tanker operated by Polembros Shipping Ltd. of London, England, and registered in Liberia. On November 5, 1988, the tanker departed Sullom Voe Terminal in the Shetland Islands off Scotland, fully loaded with North Sea Brent Crude oil which was being transported to the Come By Chance Refinery at Come-by-Chance, Newfoundland and Labrador. When the ship was about 1000 nautical miles off the coast of Newfoundland, a major North Atlantic storm arose, buffetting the ship with waves and 44-mile-per-hour winds. In response, the ship sent out a distress signal and kept heading
