  • Publication number: 20230034069
    Abstract: Various examples according to the present disclosure provide a fermentation method. The fermentation method includes producing at least about 10 g/L of a bioproduct and one or more heterologous polypeptides by fermenting a medium using an engineered microorganism. About 2 wt % to about 100 wt % of the one or more heterologous polypeptides are encapsulated intercellularly in the engineered microorganism. The method further includes isolating the engineered microorganism including the encapsulated one or more heterologous polypeptides. About 50 wt % to about 100 wt % of the one or more heterologous polypeptides retain functionality following isolation of the engineered microorganism.

  • Publication number: 20230016607
    Abstract: The present invention discloses a method to manufacture synthetic meat through recombinant expression of muscle proteins in edible biological hosts. The present invention particularly discloses to a method to manufacture synthetic meat that may overcome the issue of huge consumption of precious water, food and large rural area during the conventional practices of meat production. In addition, the method disclosed in the present invention aids in the significant reduction of animal slaughter.

  • Patent number: 10844363
    Abstract: The present invention relates to a genetically engineered yeast (e.g., Crabtree negative) that express a heterologous xylose isomerase. In a fermentation method the engineered yeast are capable of producing a bioproduct, such as ethanol, in a fermentation medium that includes xylose. Desirable bioproduct titers can be achieved when materials such as acetate are present in the fermentation medium.

  • Patent number: 9090898
    Abstract: Recombinant hosts for producing polyhydroxyalkanoates and methods of producing polyhydroxyalkanoates from renewable carbon substrates are provided. Certain recombinant hosts that produce 5 carbon chemicals such as 5-aminopentanoate (5AP), 5-hydroxyvalerate (5HV), glutarate, and 1,5 pentanediol (PDO) are also provided. One embodiment provides a recombinant host expressing a gene encoding a heterologous enzyme selected from the group consisting of a polyhydroxyalkanoate synthase and a 5-hydroxyvalerate-CoA (5HV-CoA) transferase, wherein the host produces a polymer containing 5-hydroxyvalerate. Preferably, the host expresses both a polyhydroxyalkanoate synthase and a 5HV-CoA transferase. The host can be prokaryotic or eukaryotic. A preferred prokaryotic host is E. coli. The polymers produced by the recombinant hosts can be homopolymers or copolymers of 5-hydroxyvalerate. A preferred copolymer is poly(3-hydroxybutyrate-co-5-hydroxyvalerate).
