Abstract
Bioremediation methods and kits for degrading environmental contaminants, such as chlorinated hydrocarbons, in a sample containing microorganisms uses at least one slow release compound having at least one hydrolyzable organic group capable of forming at least one alcohol, at least one organic acid, or a combination thereof, upon hydrolysis. The hydrolysis occurs over an extended period of time to provide alcohols and/or organic acids, which are used by the microorganisms to degrade the environmental contaminants.
Claims51
A bioremediation method of degrading one or more environmental contaminants in a sample containing microorganisms, the method comprising:
- determining the presence of the one or more environmental contaminants;
- and
- contacting the sample with a liquid or a solid form of at least one slow release compound having at least one hydrolyzable organic group capable of forming at least one alcohol, at least one organic acid, or a combination thereof, upon hydrolysis;
- wherein the liquid or solid slow release compound having at least one hydrolyzable organic group is provided in an amount sufficient to form at least one alcohol, at least one organic acid, or a combination thereof, in an amount sufficient for the microorganisms to degrade the one or more environmental contaminants.
A bioremediation method of degrading a halogenated organic compound in an environmental sample, the method comprising:
- determining the presence of the halogenated organic compound;
- and
- contacting the environmental sample with at least one organosilicon compound having at least one hydrolyzable organic group in the presence of at least one type of microorganism.
A kit for bioremediation of an environmental contaminant in a sample comprising at least one type of microorganism, the kit comprising:
- at least one slow release compound having at least one hydrolyzable organic group capable of forming at least one alcohol, at least one organic acid, or a combination thereof, upon hydrolysis;
- and
- instruction means for applying the compound to the sample.
A bioremediation method of degrading one or more environmental contaminants in a sample containing microorganisms, the method comprising:
- determining the presence of the one or more environmental contaminants;
- and
- contacting the sample with at least one slow release compound having at least one hydrolyzable organic group capable of forming at least one alcohol, at least one organic acid, or a combination thereof, upon hydrolysis;
- wherein the slow release compound having at least one hydrolyzable organic group is selected from the group of an organometallic compound, an organic compound, and mixtures thereof, and is provided in an amount sufficient to form at least one alcohol, at least one organic acid, or a combination thereof, in an amount sufficient for the microorganisms to degrade the one or more environmental contaminants.

- and
- contacting the sample with at least one slow release compound having at least one hydrolyzable organic group capable of forming at least one alcohol, at least one organic acid, or a combination thereof, upon hydrolysis;
- wherein the slow release compound having at least one hydrolyzable organic group is an organometallic compound and is provided in an amount sufficient to form at least one alcohol, at least one organic acid, or a combination thereof, in an amount sufficient for the microorganisms to degrade the one or more environmental contaminants.
A kit for bioremediation of an environmental contaminant in a sample comprising at least one type of microorganism, the kit comprising:
- at least one slow release compound having at least one hydrolyzable organic group capable of forming at least one alcohol, at least one organic acid, or a combination thereof, upon hydrolysis, wherein the slow release compound is selected from the group of an organometallic compound, an organic compound, and mixtures thereof;
- and
- instruction means for applying the compound to the sample.
