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 document describes biochemical pathways for producing a difunctional product having an odd number of carbon atoms in vitro or in a recombinant host, or salts or derivatives thereof, by forming two terminal functional groups selected from carboxyl, amine, formyl, and hydroxyl groups in an aliphatic carbon chain backbone having an odd number of carbon atoms synthesized from (i) acetyl-CoA and propanedioyl-CoA via one or more cycles of methyl ester shielded carbon chain elongation or (ii) propanedioyl-[acp] via one or more cycles of methyl ester shielded carbon chain elongation. The biochemical pathways and metabolic engineering and cultivation strategies described herein rely on enzymes or homologs accepting methyl ester shielded aliphatic carbon chain backbones and maintaining the methyl ester shield for at least one further enzymatic step following one or more cycles of methyl ester shielded carbon chain elongation.

Abstract: Provided herein are methods for increasing the yield of an extracellular product synthesized by an organism cultured in a continuous aerobic fermentation system. The extracellular product yield is increased through the use of an organism modified to decreased production of polyhydroxyalkanoate, to increase production of the extracellular product, and to include promoters that can be inducible in response to nutrient limitation conditions. The extracellular product yield is also increased by operating the continuous fermentation system under particular nutrient limitation conditions. Also provided are non-naturally occurring organisms that have been modified for use with the provided methods, and extracellular products made using the provided methods.

Abstract: Provided herein are systems and methods for recycling and supplementing off-gas from a gas fed reaction process. The systems and methods are particularly useful for bioprocesses that convert hydrogen gas into one or more biosynthetic products. By maintaining separate hydrogen and oxygen feed gas streams, and forming a recycle gas that introduces a target component of the supply gas to the bioreactor within a target concentration range, the yields, productivities, and safety profiles of the bioprocess can be enhanced.
