ABSTRACT:
A method is disclosed, for depolluting fresh and sea waters from hydrocarbonaceous pollutants, the improvement consisting in that the usual microorganism cultures used for oxidizing the hydrocarbons are integrated by lipophilic and floating compounds which contain slow-release nitrogen in a form which can be assimilated by such micro-organisms. Ureidic derivatives of higher aldehydes are the preferred compounds. Inert supports can be used, if necessary, and still better results are achieved when using also nonionic dispersants and freeze-dried hydrocarbon-oxidizing microorganisms.
