The algae-macrophytes of the Barents Sea in bioremediation of marine environment of oil products

Abstract

There are shown the results of the researche of the probable role of marine algae-macrophytes in cleaning the coastal waters from oil products. The results of researches demonstrate a high ability of sorption of algae Fucus vesiculosus and Ulvaria obscura to oil products: decreasing the containment of oil products in water, in parallel its accumulation in algae. A destruction of oil products of ulvaria goes as of fucus, the whole thalli: starts at the surface of algae with epiphytic hydrocarbonoxidizing bacteria which provides absorbing and neutralization of oil products by the cells of plants. The received information makes a contribution to an evidence base of participance of algae-macrophytes in bioremediation of a marine environment, allow to estimate its role in clearing the coastal waters from oil products much more higher than it was considered before. The information about the possible role of symbiotic assosiation of marine algae and hydrocarbonoxidizing bacteria in bioremediation have become a base for creation the technology of sanitary algae plantation (SAP) - plantation-biofilter, directed to cleaning the coastal waters of the Arctic Seas. The approbation of plantation at the bays of the Barents sea and the White Sea has already shown it’s high efficiency.
