  • Method improving producer gas fermentation
    Patent number: 10053711
    Abstract: Providing a microbial catalyst in a reaction broth, providing an adsorptive solid into the reaction broth, providing a producer gas into the reaction broth, and obtaining a fermentation product from the reaction broth resulting from activity of the microbial catalyst in the presence of the adsorptive solid.
    Type: Grant
    Filed: August 4, 2014
    Date of Patent: August 21, 2018
    Assignees: THE BOARD OF REGENTS FOR OKLAHOMA STATE UNIVERSITY, BRIGHAM YOUNG UNIVERSITY
    Inventors: Hasan K. Atiyeh, Randy S. Lewis, John Randall Phillips, Raymond L. Huhnke

  • ISOLATION AND CHARACTERIZATION OF NOVEL CLOSTRIDIAL SPECIES
    Publication number: 20100203606
    Abstract: A novel clostridia bacterial species (Clostridium ragsdalei, ATCC BAA-622/PTA-7826, “P11”) is provided. P11 is capable of synthesizing, from waste gases, products which are useful as biofuel. In particular, P11 can convert CO to ethanol. Thus, this novel bacterium transforms waste gases (e.g. syngas and refinery wastes) into useful products. P11 also catalyzes the production of acetate.

  • Indirect or direct fermentation of biomass to fuel alcohol
    Publication number: 20070275447
    Abstract: A novel clostridia bacterial species (Clostridium carboxidivorans, ATCC BAA-624, “P7”) is provided. P7 is capable of synthesizing, from waste gases, products which are useful as biofuel. In particular, P7 can convert CO to ethanol. Thus, this novel bacterium can transform waste gases (e.g. syngas and refinery wastes) into useful products. P7 also catalyzes the production of acetate and butanol. Further, P7 is also capable of directly fermenting lignocellulosic materials to produce ethanol and other substances.
