Sanitary algae plantation for the bioremediation of coastal waters from oil: from theory to practice
The scheme of sanitary algae plantation was depicted and successfully aprobated in the Barents and the White seas. The plantation is based on symbiotic association of brown algae: Fucus vesiculosus, Saccharina latissima and hydrocarbon oxydizing bacteria. The analysis of speed of growth and other physiological features of plantation. Biochemical and physiological characteristics for F. vesiculosus were identified which is capable to long life under conditions of constant oil pollution. The role of F. vesiculosus in the purification of sea waters from petroleum products (PP) was shown. This type is able to accumulate and to involve PP in metabolism. The dynamics of PP degradation with fucus was shown. It was found out that the oil pollution of the marine environment leads to increasing of total number of bacteria including the saprotrophic and hydrocarbon-oxidizing. The data of the taxonomic assignment of hydrocarbon bacteria dominant on the fucus surface was obtained. Updatel information of the nature symbiotic association of algae and oil-oxidizing bacteria enhances greatly understanding of the role of biological factors in the clean-up of sea waters from oil and may become the basis for the development of sanitary aquaculture.
