| 20080274035 | REVERSIBLE OXIDATION OF CARBON NANOTUBES - Carbon nanotubes have been reversibly and readily oxidized and reduced with common chemicals in solution, thereby allowing the nanotubes to be used as catalysts for chemical reactions and as stable charge storage devices. | 11-06-2008 |
| 20100159516 | ORGANIC SOLVENT PRETREATMENT OF BIOMASS TO ENHANCE ENZYMATIC SACCHARIFICATION - Biomass is pretreated using an organic solvent solution under alkaline conditions in the presence of one or more alkylamine and optionally one or more additional nucleophile to fragment and extract lignin. Pretreated biomass is further hydrolyzed with a saccharification enzyme consortium. Fermentable sugars released by saccharification may be utilized for the production of target chemicals by fermentation. | 06-24-2010 |
| 20100159517 | ORGANIC SOLVENT PRETREATMENT OF BIOMASS TO ENHANCE ENZYMATIC SACCHARIFICATION - Biomass is pretreated using an organic solvent solution, under alkaline conditions, in the presence of one or more organo-mercaptan and optionally one or more additional nucleophile to fragment and extract lignin. Pretreated biomass is further hydrolyzed with a saccharification enzyme consortium. Fermentable sugars released by saccharification may be utilized for the production of target chemicals by fermentation. | 06-24-2010 |
| 20100159518 | ORGANIC SOLVENT PRETREATMENT OF BIOMASS TO ENHANCE ENZYMATIC SACCHARIFICATION - Biomass is pretreated using an organic solvent solution under alkaline conditions in the presence of one of more sulfide (hydrosulfide) salt and optionally one or more additional nucleophile to fragment and extract lignin. Pretreated biomass is further hydrolyzed with a saccharification enzyme consortium. Fermentable sugars released by saccharification may be utilized for the production of target chemicals by fermentation. | 06-24-2010 |
| 20100159519 | ORGANIC SOLVENT PRETREATMENT OF BIOMASS TO ENHANCE ENZYMATIC SACCHARIFICATION - Biomass is pretreated using an organic solvent solution under alkaline conditions in the presence of elemental sulfur and optionally one or more alkylamine and/or one or more additional nucleophile to fragment and extract lignin. Pretreated biomass is further hydrolyzed with a saccharification enzyme consortium. Fermentable sugars released by saccharification may be utilized for the production of target chemicals by fermentation. | 06-24-2010 |
| 20100159520 | ORGANIC SOLVENT PRETREATMENT OF BIOMASS TO ENHANCE ENZYMATIC SACCHARIFICATION - Biomass is pretreated using an organic solvent solution under alkaline conditions in the presence of ammonia and optionally an additional nucleophile to fragment and extract lignin without loss of hemicellulose. Pretreated biomass is further hydrolyzed with a saccharification enzyme consortium. Fermentable sugars released by saccharification may be utilized for the production of target chemicals by fermentation. | 06-24-2010 |
| 20100159521 | OZONE TREATMENT OF BIOMASS TO ENHANCE ENZYMATIC SACCHARIFICATION - Methods for treating lignocellulosic biomass to produce readily saccharifiable carbohydrate-enriched biomass are provided. In one method, lignocellulosic biomass comprising lignin is treated with aqueous ammonia, then contacted with a gas comprising ozone at a temperature of about 0° C. to about 50° C. In another method, lignocellulosic biomass comprising lignin is contacted with a gas comprising ozone at a temperature of about 0° C. to about 50° C., then treated with aqueous ammonia. The readily saccharifiable carbohydrate-enriched biomass may be saccharified with an enzyme consortium to produce fermentable sugars. | 06-24-2010 |
| 20110212495 | COMPARTMENTALIZED SIMULTANEOUS SACCHARIFICATION AND FERMENTATION OF BIOMASS - Methods and apparatus' are disclosed for the simultaneous saccharification and fermentation of biomass providing for the compartmentalization of the saccharification process and the fermentation process resulting in decreased enzymatic end-product inhibition. | 09-01-2011 |
