Certain disclosed embodiments concern a bioremediation composition comprising microbial cells, at least one co-metabolism substrate to induce selected enzyme production by the microbial cells, and a bead or gel encapsulating the microbial cells, such as bacterial or fungi cells, and the at least one co-metabolism substrate. For certain embodiments, the substrate is a slow release compound, such as an orthosilicate that hydrolyzes to produce an alcohol growth substrate. Embodiments of a method for using the composition to transform contaminants of concern also are disclosed.

Bioremediation using co-metabolism substrates

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.
