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.
