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.
Claims38
A method for enriching monomer content in a cycloalkane oxidation process mixed organic waste stream, comprising:
- (a) combining a biocatalyst with a mixed organic waste stream from a cycloalkane oxidation process, wherein the biocatalyst is esterase (EC 3.1.1.1), cutinase (EC 3.1.1.74), polyhydroxyalkanoate (PHA) depolymerase (EC 3.1.1.75 & EC 3.1.1.76), 1,4-lactonase (EC 3.1.1.25), or gluconolactonases (EC 3.1.1.17), or combinations thereof;
- and
- (b) enzymatically converting lactone, dimeric and/or oligomeric components of said mixed organic waste stream into monomeric components.
