Abstract: The disclosed method relates to a method of recycling high relative viscosity nylon. The process involves melting a base polyamide with a dry blended mixture of dicarboxylic acid and a second polyamide. The disclosed method provides a process of controlling the relative viscosity of the combined polyamides and, in various aspects, the second polyamide may be nylon plop or other polyamide having high relative viscosity.

Abstract: Disclosed are fibers comprising a modified polyamide, such as a modified nylon-6, a modified nylon-6,6, or a modified nylon-5,6. The polyamide may be modified to contain a modified polyolefin, such as a maleated polyolefin. The disclosed fibers are hydrophobic and have surprising properties and benefits as compared to fibers having the same base polymer but without modification.

Abstract: This disclosure relates to strategies for in vivo production of certain carbon-based products, for example, aminated aliphatic compounds having a carbon chain length of C5-C19. Specifically, 7-aminoheptanoic acid is produced using a transaminase from Chromobacterium violaceum from pimelate semialdehyde using alanine, GABA (gamma aminobutyric acid) or 6-ACA as amino donors.

Abstract: Disclosed herein are methods, compositions, and hosts for synthesizing hydrocarbons, and derivatives thereof, comprising one or more isoprene units as well as salts or derivatives thereof. An aspect of the present invention thus relates to a method for biosynthesizing hydrocarbons in a recombinant host selected from non-pathogenic members of the genera Ralstonia, Wausteria, Cupriavidus, Alcaligenes, Burkholderia, or Pandoraea. Said recombinant host comprises an exogenous nucleic acid sequence encoding a polypeptide having an enzyme activity selected from 1-deoxy-D-xylulose-5-phosphate synthase (DXS) activity (EC 2.2.1.7) and isoprene synthase enzyme activity (EC 4.2.3.27).
