Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
We claim: 1. A composition for remediating 1,4-dioxane, 1,1,1-trichloroethane (1,1,1-TCA) and/or dichloroethene (DCE), comprising: microbial cells obtained from Rhodococcus rhodochrous ATCC 21198; at least one orthosilicate co-metabolism substrate selected from tetrabutyl orthosilicate (TBOS), tetra-sec-butyl orthosilicate (T2BOS), and combinations thereof, to induce selected enzyme production by the microbial cells; and a bead having at least one dimension of at least 1 millimeter or greater encapsulating the microbial cells and the at least one co-metabolism substrate. 2. A method for remediating 1,4-dioxane, 1,1,1-TCA and/or DCE, comprising: providing a composition according to claim 1 ; and contacting 1,4-dioxane, 1,1,1-TCA and/or DCE with the composition.
