  • Publication number: 20230399666
    Abstract: The present invention provides for a method for producing a rhamnolipid, the method comprising: (a) providing a genetically modified host cell comprising one or more of RhlYZAB capable of expression in the host cell in a growth or culture medium; (b) growing or culturing the host cell such that the one or more of RhlYZAB are expressed and a rhamnolipid is produced; and (c) optionally recovering the rhamnolipid from the host cell or from the growth or culture medium. In some embodiments, the host cell is a methanotroph.

  • Patent number: 9777300
    Abstract: The present invention provides for a system for converting CO2 and H2 to one or more biologically derived compounds. In some embodiments, the system comprises a host cell comprising one or more nucleic acids encoding genes for a recombinant surface display protein which is capable of tethering an electrocatalyst molecule, such as a cobalt(II) complex supported by tetradentate polypyridyl ligand 2-bis(2-pyridyl)(methoxy)methyl-6-pyridylpyridine (PY4), and enzymes for synthesizing a biologically derived compound, such as an alkane, alcohol, fatty acid, ester, or isoprenoid.
