  • Materials and methods for controlling PHA biosynthesis in PHA-generating species of the genera or and organisms related thereto
    Patent number: 11702680
    Abstract: Provided herein are methods for generating cellular biomass in continuous aerobic fermentation systems. The biomass yield, and the concentration of polyhydroxyalkanoate within the biomass, are each directed to advantageous levels by operating the continuous fermentation system under particular nutrient limitation conditions. Also provided are biomass produced using the provided methods, and animal feed compositions including the provided biomass.
    Type: Grant

  • MATERIALS AND METHODS FOR CONTROLLING LIMITATION CONDITIONS IN PRODUCT BIOSYNTHESIS FOR NON-PHB GENERATING SPECIES OF THE GENERA RALSTONIA OR CUPRIAVIDUS AND ORGANISMS RELATED THERETO
    Publication number: 20190352674
    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.

  • Stain-resistant, pigmented nylon fibers
    Patent number: 5830572
    Abstract: Producer-colored nylon fibers which are stain-resistant to acid dyes are made by adding pigment to nylon copolymers containing 0.25-4.0 percent by weight of an aromatic sulfonate or an alkali metal salt thereof. In addition process advantages relating to the use of the same copolymers in making pigmented nylon fibers are also disclosed.

  • Method for producing solution dyed articles from thermoplastic polymers
    Patent number: 5756020
    Abstract: A process for producing solution dyed extruded articles from thermoplastic polymer wherein each colorant is contained in a separate color concentrate and each concentrate is fed to an extruder through a separate gravimetric feeder where the concentrates are melt blended with the thermoplastic polymer prior to extruding.
