Patent number: 11634735Abstract: The present invention provides for novel metabolic pathways leading to propanol, alcohol or polyol formation in a consolidated bioprocessing system (CBP), where lignocellulosic biomass is efficiently converted to such products. More specifically, the invention provides for a recombinant microorganism, where the microorganism expresses one or more native and/or heterologous enzymes; where the one or more enzymes function in one or more engineered metabolic pathways to achieve: (1) conversion of a carbohydrate source to 1,2-propanediol, isopropropanol, ethanol and/or glycerol; (2) conversion of a carbohydrate source to n-propanol and isopropanol; (3) conversion of a carbohydrate source to isopropanol and methanol; or (4) conversion of a carbohydrate source to propanediol and acetone; wherein the one or more native and/or heterologous enzymes is activated, upregulated or downregulated.Type: GrantFiled: July 1, 2020Date of Patent: April 25, 2023Assignee: Lallemand Hungary Liquidity Management LLCInventors: John E. McBride, Vineet Rajgarhia, Arthur J. Shaw, IV, Shital A. Tripathi, Elena Brevnova, Nicky Caiazza, Johannes Pieter Van Dijken, Allan C. Froehlich, William Ryan Sillers, James H. Flatt

Publication number: 20230028975Abstract: The present invention is directed to a yeast strain, or strains, secreting a full suite, or any subset of that full suite, of enzymes to hydrolyze corn starch, corn fiber, lignocellulose, (including enzymes that hydrolyze linkages in cellulose, hemicellulose, and between lignin and carbohydrates) and to utilize pentose sugars (xylose and arabinose). The invention is also directed to the set of proteins that are well expressed in yeast for each category of enzymatic activity. The resulting strain, or strains can be used to hydrolyze starch and cellulose simultaneously. The resulting strain, or strains can be also metabolically engineered to produce less glycerol and uptake acetate. The resulting strain, or strains can also be used to produce ethanol from granular starch without liquefaction.Type: ApplicationFiled: October 13, 2021Publication date: January 26, 2023Inventors: Elena Brevnova, John E.

Patent number: 9605269Abstract: One aspect of the invention relates to a genetically modified thermophilic or mesophilic microorganism, wherein a first native gene is partially, substantially, or completely deleted, silenced, inactivated, or down-regulated, which first native gene encodes a first native enzyme involved in the metabolic production of an organic acid or a salt thereof, thereby increasing the native ability of said thermophilic or mesophilic microorganism to produce lactate or acetate as a fermentation product. In certain embodiments, the aforementioned microorganism further comprises a first non-native gene, which first non-native gene encodes a first non-native enzyme involved in the metabolic production of lactate or acetate. Another aspect of the invention relates to a process for converting lignocellulosic biomass to lactate or acetate, comprising contacting lignocellulosic biomass with a genetically modified thermophilic or mesophilic microorganism.Type: GrantFiled: May 5, 2011Date of Patent: March 28, 2017Assignee: Lallemand Hungary Liquidity Management LLCInventors: William Ryan Sillers, Hans Van Dijken, Steve Licht, Arthur J.
