There was shown the role of live and dry algae Fucus vesiculosus (Phaeophyceae) in the purification of the coastal waters from petroleum products. It was revealed that live algae can be effectively used for preventive, daily purification of marine water, when the content of diesel fuel does not exceed 3 mg/l. For the first time, the prospect of using dry fucus for bioremediation of marine water in emergencies creating a concentration of petroleum products in water of 1 g/l has been determined. In the case of using living plants to neutralize toxicant, the decisive role in the process belongs to the symbiotic association of algae and hydrocarbon-oxidizing bacteria. In case of using dry algae, dried macrophytes become a reservoir for the accumulation of diesel fuel. The main work on the destruction of hydrocarbons, probably, lies on HOB, as well as on physicochemical processes. Metabolic processes inherent in living algae and leading to the destruction of petroleum hydrocarbons weren’t determined in this case.
