Abstract: Embodiments of the present invention relate to methods for the biosynthesis of di- or trifunctional C7 alkanes in the presence of isolated enzymes or in the presence of a recombinant host cell expressing those enzymes. The di- or trifunctional C7 alkanes are useful as intermediates in the production of nylon-7, nylon-7,x, nylon-x,7, and polyesters.

Abstract: This document describes biochemical pathways for producing adipic acid, caprolactam, 6-aminohexanoic acid, 6-hydroxyhexanoic acid, hexamethylenediamine or 1,6-hexanediol by forming two terminal functional groups, comprised of carboxyl, amine or hydroxyl groups, in a C6 aliphatic backbone substrate. These pathways, metabolic engineering and cultivation strategies described herein rely on CoA-dependent elongation enzymes or analogues enzymes associated with the carbon storage pathways from polyhydroxyalkanoate accumulating bacteria.

Abstract: Disclosed is a process for removing 2-cyanocyclopentylideneimine (CPI) from a mixture containing CPI and dinitrile. The process comprises reacting CPI with an amine. The reaction may take place in the presence of water, and optionally, a catalyst. CPI is converted to products with a low volatility compared to the dinitrile.
