  • Mutant strain for producing cellulase and xylanase and preparation method thereof
    Patent number: 11236375
    Abstract: The present invention relates to a novel mutant strain Clostridium thermocellum M2_15-C8 and a genetic modification process of said bacteria, wherein the mutant strain according to this invention can produce cellulase and xylanase more than the wild type. Moreover, the obtained enzymes can be used to digest the pretreated bagasse to further produce sugars effectively.
    Type: Grant
    Filed: May 30, 2018
    Date of Patent: February 1, 2022
    Assignee: PTT Global Chemical Public Company Limited
    Inventors: Chakrit Tachaapaikoon, Khanok Ratanakhanokchai, Patthra Pason, Rattiya Waeonukul, Prattana Ketbot, Wikanda Techanan, Kraileark Kittisuriyanont, Narong Kaewsuwan

  • Method for recycling enzyme
    Patent number: 9074200
    Abstract: In saccharification of cellulose, chimeric ?-glucosidase having a region exhibiting thermophilic bacteria-derived ?-glucosidase activity and a module combinable to cellulose is used along with cellulosome, and at the completion of saccharification of cellulose, a cellulosic substrate is added to make the chimeric ?-glucosidase and cellulosome attach to the cellulosic substrate for separation.
