Abstract

Oil spills in marine environments are common due to the intense flow of transport. One of the ways to reduce the effects caused by these spills is bioremediation. A biosurfactant produced by Acinetobacter venetianus AMO1502, a strain isolated from oil spilled off the Brazilian coast, was investigated as a bioremediation agent. The highest cell growth and biosurfactant production were obtained using a culture medium supplemented with NaCl. The biosurfactant had high emulsifying activity and reduced the surface tension of water by up to 41.7 %. This biomolecule showed high stability related to temperature, pH, and NaCl addition as petroderivate removal agent, reaching 25 % removal of the engine oil in sand and 12 % removal of the oil in an aqueous medium, also reducing oil stains adsorbed on contaminated stones.
