Abstract
Abstract Compositions are disclosed, which are adapted to depollute fresh and sea water bodies from crude oil and petroleum product pollution by microbial action. The growth of micro-organisms capable of metabolizing hydrocarbons is exalted by certain combination of nutrients, such as lecithin as a phosphorus source, hydantoins, amides allophanates, polyamines, acyl-ureas and esters of the hydantoic and allantoic acids as the nitrogen sources. Ureido-derivatives of amides are also contemplated as additional nutrients.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
124 words
A composition adapted to depolluting fresh and sea water bodies from crude oil, petroleum products and their derivatives, containing phosphorus and slow-release nitrogen in a form which can be assimilated by aquatic micro-organisms capable of metabolizing hydrocarbons, said composition consisting essentially of soybean lecithin as said phosphorus source, and as said nitrogen source a nitrogen source selected from the group consisting of spermidin, butyl hydantoinate and butyl allantoinate, said lecithin and said nitrogen in said phosphorus and slow-release nitrogen containing composition being present in an amount sufficient to increase the natural biodegradation of said pollutants caused by the metabolization of hydrocarbons by said micro-organisms, the ratio by weight of said nitrogen to said phosphorus in said composition being greater than about 12 to 1.
Claim 2
Dependent Claim
124 words

Claim 3
Dependent Claim
122 words
A composition adapted to depolluting fresh and sea water bodies from crude oil, petroleum products and their derivatives, containing phosphorus and slow-release nitrogen in a form which can be assimilated by aquatic micro-organisms capable of metabolizing hydrocarbons, said composition consisting essentially of soybean lecithin as said phosphorus source, and as said nitrogen source mixtures of a nitrogen source including 2, 2'-hydroxyethyloleylamide and the condensation product of isovaleric aldehyde and urea, said phosphorus and said nitrogen in said composition being present in an amount sufficient to increase the natural biodegradation of said pollutants caused by the metabolization of hydrocarbons by said aquatic microorganisms, the ratio by weight of said nitrogen to said phosphorus in said composition being greater than about 12 to 1.
Claim 4
Dependent Claim
122 words
