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
Oil Pollution Act of 1990 limited safeguards against the hazards of oils spills. In 1976, a bill to create a cohesive safe measure for oil pollution was introduced to Congress. Neither the House of Representatives nor the Senate could agree on a single statue and the bill fell out of consideration numerous times. On March 24, 1989, the Exxon Valdez hit aground in the Prince Williams Sound and spilled nearly 11 million gallons of crude oil—the largest marine oil spill in recorded history up to that point. Soon afterward, in June 1989, three smaller spills occurred within coastal waters of the United States. This was
