NOVELTY - The method for biodegradation of organic compounds of group of hydrocarbons, fats, oils and/or waxes and their derivatives in polluted aqueous and/or non-aqueous media in presence of a dispersing agent, comprises treating the medium polluted with the organic compounds by dispersing agent and microorganisms. The dispersing agent is initially delivered into the medium polluted with the organic compounds and then the microorganisms are added to the medium or the microorganisms are initially delivered into the medium polluted with the organic compounds and then the dispersing agent is added.    USE - Method for biodegradation of organic compounds of group of hydrocarbons, fats, oils and/or waxes and their derivatives in polluted aqueous and/or non-aqueous media in presence of a dispersing agent, where the aqueous media are polluted open sea, inland water, media of water storage tank and media of wastewater treatment plants and the non-aqueous media are media of polluted surfaces and regions in soil contaminated areas, service stations and restaurants (all claimed).    ADVANTAGE - The method ensures effective and rapid biodegradation of the organic compounds in the polluted media with high efficiency and less effort.    DETAILED DESCRIPTION - The method for biodegradation of organic compounds of group of hydrocarbons, fats, oils and/or waxes and their derivatives in polluted aqueous and/or non-aqueous media in presence of a dispersing agent, comprises treating the medium polluted with the organic compounds by dispersing agent and microorganisms. The dispersing agent is initially delivered into the medium polluted with the organic compounds and then the microorganisms are added to the medium or the microorganisms are initially delivered into the medium polluted with the organic compounds and then the dispersing agent is added to the medium, where the dispersing agent is a ionic-, non-ionic- and amphoteric surface-active agent and is a mixture with petroleum distillates. The dispersing agent is used in a concentration of 3-7% related to the quantity of the organic compounds in the polluted medium. A solution of microorganisms is added to the medium. The microorganisms are bacteria, yeast and/or fungi, where the genus of Acinetobacter, Alcaligenes, Bacillus, Pseudomonas, Alcanivorax, Cycloclasticus, Marinobacter, Neptunomonas, Oleiphilus, Oleispira and/or Thalassolitus is used as bacterial cells, the genus of Phanerochaete, Aspergillus, Penicillium, Fusarium, Amorphotheca, Neosartorya, Paecilomyces, Talaromyces and/or Graphium is used as fungi cells and the genus of Candidais used as yeast cells. The microorganisms are used in a concentration of 103-1015 cells/ml related to the quantity of the organic compounds in the polluted medium. The dispersing agent and the microorganisms are sprayed onto the polluted medium. An INDEPENDENT CLAIM is included for a combination product.
