Abstract
The present invention describes methods for the detoxification of a mixture of nitrile compounds, or a mixture of nitrile and amide compounds by conversion of the nitrile compound(s) to the corresponding amide or acid compounds using a pure culture of an induced microorganism strain capable of converting a nitrile moiety to an amide or acid moiety. If an amide is formed or is present in the mixture, the amide can be further converted, using the present methods for detoxification, to the corresponding acid. The acid can then, if desired, be further degraded to CO.sub.2, H.sub.2 O and biomass. The induced pure cultures are able to detoxify a mixture of nitrites or a mixture of nitriles and amides which are typically present, in high concentration(s), in nitrile production waste streams. The present invention further discloses methods for removing a nitrile compound from an amide preparation, such as an acetamide or acrylamide preparation containing an unwanted nitrile compound, using an induced pure culture of an induced microorganism strain capable of converting a nitrile moiety to an amide or acid moiety. The pure cultures are able to purify or reduce the toxicity of the amide preparation thus improving purity and amide product yield from the amide preparation. The present invention further discloses methods for the conversion of a mixture of amide compounds to the corresponding acid compounds using a pure culture of an induced microorganism strain capable of converting an amide moiety to an acid moiety. This invention also discloses kits, biofilters and methods for use of the kits and biofilters for detoxification containing the useful microorganism strains.
