  • Muconic acid-producing transformed microorganism and use thereof
    Patent number: 11845972
    Abstract: The objective of the present invention is to provide a microorganism that makes it possible to produce muconic acid from a lignin-derived aromatic compound with sufficient economic efficiency and without depending on the type of lignin, and a method of producing muconic acid using the microorganism. The objective can be achieved by a transformed microorganism wherein the host microorganism is a microorganism of the genus Pseudomonas that has pcaH gene, pcaG gene, catA gene, and catB gene on its chromosome, and that can assimilate an aromatic compound derived from syringyl lignin; and wherein the transformed microorganism lacks at least one gene selected from the group consisting of pcaH gene and pcaG gene on its chromosome, lacks catB gene on its chromosome, and expresses aroY gene inserted; and a method of producing muconic acid using the transformed microorganism and the like.
    Type: Grant
    Filed: October 17, 2019
    Date of Patent: December 19, 2023
    Assignee: HIROSAKI UNIVERSITY
    Inventors: Tomonori Sonoki, Eiji Masai, Naofumi Kamimura
