The invention is particularly suited to separate water soluble gas components from a gas stream. The water soluble gas components can be used to condition the biomass for additional use, such as a conditioned feed for a biofuel. In general, the conditioned biomass will have increased enzyme digestibility, making the conditioned biomass highly suitable as feedstock for biofuel production.Type: GrantFiled: June 1, 2010Date of Patent: March 12, 2013Assignee: Michigan Biotechnology InstituteInventors: Timothy J. Campbell, Farzaneh Teymouri, David K. Jones

Patent number: 8323931Abstract: A fermentation process for the production of cellulase mixtures is provided. The process comprises providing a genetically modified host filamentous fungus that overexpresses a Xyr1 transcription factor and/or that is partially or completely deficient in expressing one or more hemicellulase enzyme. The host filamentous fungus is cultured in a medium comprising a carbon source. The carbon source contains from about 60 wt % to about 100 wt % hemicellulose-derived carbohydrate and less than 5% of a cellulase-inducing carbohydrate or contains from about 25 wt % to about 100% wt % hemicellulose-derived sugar alcohol in combination with from about 0 wt % to about 75 wt % glucose, glycerol or a combination thereof.Type: GrantFiled: November 3, 2009Date of Patent: December 4, 2012Assignee: Iogen Energy CorporationInventors: Loreta Gudynaite-Savitch, Christopher D. Hindle, Theresa C. White

Publication number: 20120196342Abstract: The present invention relates to methods of reducing the toxicity of lignocellulosic hydrolysates which comprise one or more inhibitors. One method reduces the amount of furfural inhibitor leading to a more effective process. Another method reduces the amount of xylitol produced during the fermentation of xylose present in lignocellulosic hydrolysates. Naturally occurring aldo/keto reductase enzymes, as well as, enzymes produced by recombinant cells or by selective adaptation may be employed.Type: ApplicationFiled: February 1, 2011Publication date: August 2, 2012Inventors: Rachel Ruizhen Chen, Manoj Agrawal
