  • Engineered microbes and methods for microbial oil production
    Patent number: 9862977
    Abstract: Some aspects of this invention provide engineered microbes for oil production. Methods for microbe engineering and for use of engineered microbes are also provided herein. In some embodiments, microbes are provided that are engineered to modulate a combination of rate-controlling steps of lipid synthesis, for example, a combination of a step generating metabolites, acetyl-CoA, ATP or NADPH for lipid synthesis (a push step), and a step sequestering a product or an intermediate of a lipid synthesis pathway that mediates feedback inhibition of lipid synthesis (a pull step). Such push-and-pull engineered microbes exhibit greatly enhanced conversion yields and TAG synthesis and storage properties.
    Type: Grant
    Filed: November 19, 2014
    Date of Patent: January 9, 2018
    Assignee: Massachusetts Institute of Technology
    Inventors: Gregory Stephanopoulos, Mitchell Tai, Sagar Chakraborty
