  • Publication number: 20240384311
    Abstract: Provided are microorganisms for making polyhydroxylalkanoate (PHA) compounds. For instance, the microorganism can include a polyhydroxylalkanoate (PHA) synthase (phaC) gene and one or both of an isocaprenoyl-CoA:2-hydroxyisocaproate CoA-transferase (hadA) gene and a propionate CoA-transferase (pct) gene. In some cases, the species of the microorganism is a Cupriavidus necator bacteria that has been genetically modified to include the PHA and hadA or pct genes.

  • Patent number: 10273510
    Abstract: Described here is a method for increasing the transfer of a gas substrate in microbial fermentation, comprising incubating an emulsion comprising an oil phase and an aqueous phase droplet dispersed in the oil phase, and supplying the gas substrate to the oil phase, wherein the aqueous phase droplet comprises a microorganism, and wherein the emulsion is stabilized by a surfactant or an amphiphilic particle that is adsorbed to an interface of the oil phase and the aqueous phase. Also described is an emulsion for microbial fermentation, comprises an oil phase and an aqueous phase droplet dispersed in the oil phase, wherein the aqueous phase droplet comprises a microorganism, wherein the emulsion comprises a gas substrate externally-supplied to the oil phase, and wherein the emulsion is stabilized by a surfactant or an amphiphilic particle that is adsorbed to an interface of the oil phase and the aqueous phase.

  • Patent number: 6645756
    Abstract: A method of remediating an environment contaminated with carbon tetrachloride by introducing Pseudomonas strain sp. KC (PsKC) into the environment under iron limiting conditions and converting the carbon tetrachloride directly to carbon dioxide and a non-volatile water soluble fraction. Further, conditions providing a niche advantage for PsKC in accordance with the invention allow for the use of PsKC as a vector in various other environmental conditions for introducing specific activities of the PsKC, whether naturally occurring or genetically altered, into those environments.
