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: The present invention relates to flame-retardant polyamide compositions. In various aspects, the present invention provides a flame-retardant polyamide composition including a polyamide that is about 30 wt % to about 99 wt % of the composition. The polyamide has a relative viscosity (RV) of ≥20 to ≤33 as measured as an 8.4 wt % solution in 90% formic acid. The composition also includes one or more flame-retardant additives. Various aspects of the present invention provide compositions having enhanced flame-retardant properties as compared to corresponding compositions including the same or greater concentration of flame-retardant additive but using a polyamide that has an RV that is 33.

Abstract: This document describes biochemical pathways for producing butadiene by forming two vinyl groups in a butadiene synthesis substrate. These pathways described herein rely on enzymes such as, inter alia, a decarboxylating thioesterase, cytochrome P450, or dehydratases for the final enzymatic step.

Abstract: Nonnaturally occurring host cells altered to increase their ability to transfer genetic molecules into the host cells as compared to an unaltered host cell are provided. Also provided are methods for identifying endogenous loci of a host cell which inhibit transformation efficiency and/or electroporation of genetic molecules into the cell as well as methods for producing nonnaturally occurring host cells with enhanced transformation efficiency and/or the modified ability to allow for genomic integration of an exogenous DNA sequence via electroporation. Methods for producing biochemicals and products produced with the nonnaturally occurring host cells are also provided. In particular, a host Cupriavidus necator cell is provided in which a chromosomal gene encoding a restriction endonuclease has been disrupted, leading to an increase in transformation efficiency.

Abstract: This document describes biochemical pathways that include the production of 3-oxopent-4-enoyl-CoA by condensation of acryloyl-CoA and acetyl-CoA using a β-ketothiolase with a SER-HIS-HIS catalytic triad. These pathways described herein rely on enzymes such as, inter alia, dehydrogenases, dehydratases and β-ketothiolases.

Abstract: Resins for improved flow in injection molding, molded articles made from the same, and methods of using the same. A molded article formed from a polymer feed includes nylon-6,6. The molded article also includes a thin elongated profile including a thickness of up to 1.5 mm and a flow length of at least 25 cm. An absolute value of ARV of the molded article as compared to the polymer feed is from 0 to 5, the RV determined according to ASTM D789.
