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.

History of the oil tanker engines, as opposed to the older steam engines. The "Vandal", the first diesel-electric ship, was capable of carrying 750 long tons of refined oil was powered by three diesel motors. The larger "Sarmat" employed four 180 h.p. engines. The first seagoing diesel-powered tanker, 4,500 ton "Mysl", was built by Nobel's competitors in Kolomna. Nobel responded with "Emanuel Nobel" and "Karl Hagelin", 4,600 long ton kerosene tankers with engines. The 475 ft., 7-masted schooner "Thomas W. Lawson", built in 1902, was the largest purely sail tanker ever built. It carried coal, and oil in barrels from Texas to the East Coast
