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.
Claims58
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;
- and
- (b) enzymatically converting dimeric and/or oligomeric components of said waste stream into monomeric components.
A composition comprising a mixed organic waste stream of a cycloalkane oxidation process and a biocatalyst.
The composition of 42, wherein the enzyme is a hydrolase.
A method for fed batch or continuous cultivation of microorganisms, comprising
- cultivating microorganisms in the presence of NVR, COP acid, or water wash, and wherein said NVR, COP acid, or water wash supply at least some of the carbon required for growth of said microorganisms, and
- enriching the monomer content in said NVR, COP acid, or water wash, wherein said microorganisms enzymatically convert dimeric and/or oligomeric components of said waste stream into monomeric components.
