Abstract: The bioremediation of marine sediments polluted by crude oil was studied through two field experiments to evaluate the interest of fertilisation and oxygenation on a muddy sediment, to test the toxicity of these techniques on a marine organism, and to determine the efficiency of two bioremediation products on oil biodegradation kinetic. The experiment on muddy sediment shown that first bioremediation techniques should, in the first place, compensate the oxygen depletion and, only after, they should supply nutrient. The results of the second experiment shown that bioremediation product efficiency is strongly linked to environmental parameters, and particularly to marine hydro dynamism. The efficiency of bioremediation techniques as a response method to cleanup coasts affected by an oil spill has been acknowledged but bioremediation treatments should be implemented as a fine cleanup method once standard cleanup is terminated.
