Bioremediation technologies of oil-contaminated soils and subsoils: patent review

The paper presents an analysis of the main directions of patenting technologies for bioremediation of soils and soils, which have been confirmed by oil pollution. Methods of soil and water purification using microorganisms and plants are considered. The main aspects of bioremediation in the zone of action of oil pollutants are highlighted. The main attention is paid to the method of using plants in the purification of soils contaminated with petroleum products. The classification of phytormediation and the features of the action of the above purification methods are given. The main advantages of phytoremediation as a method of application for purification in oil pollution are noted. The main species, families of plants and the frequency of their applicability in cleaning are analyzed. The mechanism of action of phytoremediation technologies is determined. The analysis of preparatory measures for conducting phytotesting is carried out. The basic properties of plants as heavy metal scavengers are taken into account.
