  • Process for the modification of alkanes, fatty acids and fatty alcohols
    Patent number: 10975360
    Abstract: The present invention relates to a process for the microbial in-chain hydroxylation of C12 to C16 fatty acids, alcohols and alkanes at position ?-7, the process including the use of a microorganism expressing a cytochrome P450 monooxygenase CYP505E3 or related fungal cytochrome P450 monooxygenases sharing at least 70% amino acid identity in the production of a hydroxylated product or secondary product. The present invention further relates to a process for the preparation of lactones, esters and polymers by hydroxylation of the corresponding fatty acids, fatty alcohols and alkane precursors by a recombinant cytochrome P450 monooxygenase CYP505E3 or related fungal cytochrome P450 monooxygenases sharing at least 70% amino acid identity.
    Type: Grant
    Filed: February 10, 2017
    Date of Patent: April 13, 2021
    Assignee: UNIVERSITY OF THE FREE STATE
    Inventors: Martha Sophia Smit, Diederik Johannes Opperman, Alizé Pennec, Jacqueline Van Marwijk, Mpeyake Jacob Maseme, Alberto Perojil Jimenez

  • Isolation of a protein responsible for uranium (VI) reduction
    Patent number: 8685688
    Abstract: The present invention relates to the isolation and characterization of a protein responsible for the reduction of uranium (VI) to uranium (IV). The present invention extends to the use of the isolated protein in the reduction of uranium (VI) to uranium (IV) and further extends to a process for the bioremediation, or at least partial remediation, of a site contaminated with a source of U (VI). According to a first aspect thereof, the present invention provides an isolated polypeptide derived from Thermus scotoductus strain SA-01 that is responsible for the reduction of uranium (VI), in a source of uranium (VI), to uranium (IV), wherein the polypeptide comprises the amino acid sequence of SEQ ID No: 1.
