  • Phosphate sensing microbial gene switch
    Patent number: 12649699
    Abstract: Genetically engineered bacteria which express RNAs or proteins that produce ammonia upon decreases in phosphate concentrations are disclosed.
    Type: Grant
    Filed: January 31, 2025
    Date of Patent: June 9, 2026
    Assignee: SWITCH BIOWORKS, INC.
    Inventors: Caroline Kukolj, Tim Schnabel, Timothy Lyndon Haskett, Gregory Alexander Knauf, Tomasz Zajkowski, Elizabeth Leigh Ordeman, Niklaus Hoyt Evitt, James Pearce, Sandipan Samaddar, Daniel Torres Naylor, Hsiao-Han Lin, Alexis Makena Chun
  • Inducible ammonia production from a symbiotic diazotroph, methods of creation and uses thereof
    Patent number: 12460213
    Abstract: The present disclosure describes systems and methods capable of fixing atmospheric nitrogen into bio-available nitrogenous compounds, including ammonia. Embodiments of the present disclosure are directed to synthetic DNA constructs encoding genes to allow release of bio-available nitrogenous compounds in nitrogen fixing diazotrophic organisms. Many of these constructs encode these genes in inducible and constitutive means, such that inducible embodiments can be activated at select times. Additional embodiments are directed to genetically engineered diazotrophs utilizing these constructs to produce bio-available nitrogenous compounds. Further embodiments are directed to methods to create these constructs and organisms as well as to use these constructs and organisms.
    Type: Grant

    Date of Patent: November 4, 2025
    Assignee: The Board of Trustees of the Leland Stanford Junior University Stanford, CA
    Inventors: Tim Schnabel, Elizabeth Sattely
