Abstract
The invention relates to methods for enriching monomer content in a cycloalkane oxidation process mixed organic waste stream. In particular, the methods involve combining a biocatalyst with a mixed organic waste stream from a cycloalkane oxidation process, and enzymatically converting dimeric and/or oligomeric components of said waste stream into monomeric components. The methods may enrich the content of diacids, adipic acid, and/or other α,ω-difunctional C6 alkanes in the mixed organic waste stream. Additionally, the treated mixed organic waste streams may have improved burning efficiency.

-58. (canceled)
A recombinant host cell comprising at least one exogenous nucleic acid encoding a hydrolase classified under EC 3.1.1.-, wherein the hydrolase classified under EC 3.1.1.-, when contacted with a mixed organic waste stream from a cycloalkane oxidation process, hydrolyzes at least a portion of dimeric, oligomeric or cyclic esters of the mixed organic waste stream into aliphatic monomeric components.
