Gene Knockout Mesophilic And Thermophilic Organisms, And Methods Of Use Thereof

View page
US Patent:
8435770, May 7, 2013
Filed:
May 9, 2008
Appl. No.:
12/599458
Inventors:
David Anthony Hogsett - Grantham NH, US
Vineet Badriphrajad Rajgarhia - Lebanon NH, US
Assignee:
Mascoma Corporation - Lebanon NH
International Classification:
C12P 7/06
C12N 1/20
C12N 15/00
C07H 21/04
US Classification:
435161, 4352523, 4353201, 536 232
Abstract:
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 ethanol 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 ethanol. Another aspect of the invention relates to a process for converting lignocellulosic biomass to ethanol, comprising contacting lignocellulosic biomass with a genetically modified thermophilic or mesophilic microorganism.

Thermophilic Organisms For Conversion Of Lignocellulosic Biomass To Ethanol

US Patent:
20090221049, Sep 3, 2009
Filed:
May 1, 2007
Appl. No.:
12/299070
Inventors:
Sunil G. Desai - Andover MA, US
Lee R. Lynd - Meriden NH, US
Mikhail V. Tyurin - BainBridge GA, US
Kara Podkaminer - Jamesville NY, US
John Bardsley - Cambridge MA, US
David Anthony Hogsett - Grantham NH, US
International Classification:
C12P 7/06
C12N 1/21
C12N 15/11
C12N 15/00
US Classification:
435161, 4352523, 536 231, 4353201
Abstract:
Mutant thermophilic organisms that consume a variety of biomass derived substrates are disclosed herein. Strains of with acetate kinase and phosphotransacetylase expression eliminated are disclosed herein. Further, strain ALK1 has been engineered by site directed homologous recombination to knockout both acetic acid and lactic acid production. Continuous culture involving a substrate concentration challenge lead to evolution of ALK1, and formation of a more robust strain designated ALK2. The organisms may be utilized for example in thermophilic SSF and SSCF reactions performed at temperatures that are optimal for cellulase activity to produce near theoretical ethanol yields without expressing pyruvate decarboxylase.

Microbial Treatment Of Lignocellulosic Biomass

View page
US Patent:
20110177573, Jul 21, 2011
Filed:
Aug 3, 2009
Appl. No.:
13/055783
Inventors:
Sarah All - White River Junction VT, US
David Anthony Hogsett - Grantham NH, US
International Classification:
C12P 7/06
US Classification:
435161
Abstract:
Aspects of the present invention relate to methods of microbially treating lignocellulosic biomass using cellulose- and/or hemicellulose-degrading bacteria. In certain embodiments, the microbially treated material is then subjected to thermal and/or chemical pretreatment. In tandem with the microbial treatment the thermal and/or chemical pretreatment may result in the production of fewer degradation products, thereby allowing for higher overall yields of ethanol per ton of starting biomass.

Modification Of Hydrogenase Activities In Thermophilic Bacteria To Enhance Ethanol Production

US Patent:
20110256601, Oct 20, 2011
Filed:
Dec 17, 2008
Appl. No.:
12/808764
Inventors:
Lee Lynd - Meriden NH, US
David A. Hogsett - Grantham NH, US
Assignee:
THE TRUSTEES OF DARTMOUTH COLLEGE - Hanover NH
International Classification:
C12P 7/10
C12N 1/19
C12N 9/02
C12P 7/06
C12N 1/20
C07H 21/04
C12N 1/21
C12N 15/63
US Classification:
435165, 4352523, 4352542, 4353201, 435161, 4352521, 536 237, 435189
Abstract:
Bacteria consume a variety of biomass-derived substrates and produce ethanol. Hydrogenase genes have been inactivated m to generate mutant strains with reduced hydrogenase activities. One such mutant strain with both the ldh and hydtrA genes inactivated shows a significant increase in ethanol production. Manipulation of hydrogenase activities provides a new approach for enhancing substrate utilization and ethanol production by biomass-fermenting microorganisms.

Production Of Pure Lignin From Lignocellulosic Biomass

View page
US Patent:
20120108798, May 3, 2012
Filed:
Oct 16, 2009
Appl. No.:
13/124255
Inventors:
Kevin S. Wenger - Hanover NH, US
David A. Hogsett - Grantham NH, US
Michael Ladisch - West Lafayette IN, US
Assignee:
Mascoma Corporation - Lebanon , NH
International Classification:
C08H 7/00
C12S 3/00
US Classification:
530500, 435267
Abstract:
The present invention is directed to a process of producing substantially pure lignin from lignocellulosic biomass, which comprises: pre-treating a lignocellulosic feedstock to produce a reactive lignin-carbohydrate mixture; biologically-reacting the carbohydrates in the mixture, separating remaining solids from the liquid fermentation products, and drying the resulting solids to yield a substantially pure lignin product. Optionally, the lignin product may be washed and subjected to a second hydrolysis step. Optionally, the lignin product may be further processed by hydrotreating and/or pyrolysis in order to yield desirable products such as fuel additives.
