The present disclosure provides methods to produce ketones suitable for use as fuels and lubricants by catalytic conversion of an acetone-butanol-ethanol (ABE) fermentation product mixture that can be derived from biomass.

Method to convert fermentation mixture into fuels

The present disclosure generally relates to the catalytic conversion of alcohols into hydrocarbon ketones suitable for use as fuels. More specifically, the present disclosure relates to the catalytic conversion of a mixture of isopropanol-butanol-ethanol (IBE) or acetone-butanol-ethanol (ABE), into ketones suitable for use as fuels. The ABE or IBE mixtures may be obtained from the fermentation of biomass or sugars.

Methods to produce fuels

The present disclosure relates to mutant thermostable glycosyl hydrolases family 7 enzymes, including mutantendoglucanase I. In particular, the present disclosure relates to mutant thermostable enzymes, compositions containing the enzymes, and methods of use thereof.

[object Object]

Hydrolysis and degradation of cellulose-containing biomass by use of a polypeptide having cellulase activity is provided. Also provided are polypeptides having cellulase activity, such as archaeal cellulases, polynucleotides encoding the polypeptides, and compositions containing the polypeptides, and methods of use thereof.

Polypeptides for use in the deconstruction of cellulose

The present invention provides for a composition comprising an ionic liquid and a thermostable cellulose, and a method of hydrolyzing a cellulose, comprising: (a) providing a composition comprising a solution comprising an ionic liquid and a cellulose, and (b) introducing a thermostable cellulase to the solution, such that the cellulose is hydrolyzed by the cellulase. The present invention also provides for athermostable cellulase mutant with increased cellulase activity.

Thermostable cellulases, and mutants thereof, capable of hydrolyzing cellulose in ionic liquid

The present invention provides for a composition comprising a solution comprising (a) an ionic liquid (IL) or ionic liquid-aqueous (ILA) phase and (b) an organic phase, wherein the solution comprises a sugar and a boronic acid. The present invention also provides for a method of removing a sugar from a solution, comprising: (a) providing a solution comprising (i) an IL or ILA phase and (ii) an organic phase, wherein the solution comprises an IL, a sugar and a boronic acid; (b) contacting the sugar with the boronic acid to form a sugar-boronic acid complex, (c) separating the organic phase and the aqueous phase, wherein the organic phase contains the sugar-boronic acid complex, and optionally (d) separating the sugar from the organic phase.

Recovery of sugars from ionic liquid biomass liquor by solvent extraction

The present invention relates to an adsorbent polymer having improved selectivity for cadmium ion, comprising a water-insoluble polymeric material having available surface pendant chelating groups having a multiplicity of thiol (--SH) groups, wherein pairs of thiol groups are connected by a chain R having between about 10 and 16 atoms of the structure: ##STR1## which thiol terminated chains are capable of chelating cadmium ion in rings of between about 11 and 17 atoms, and

Cadmium ion-chelating synthetic polymers and process thereof

A method is provided for producing a product by enzyme-catalyzed reaction using supercritical fluid as a solvent. Improved reaction times, conversion efficiencies and/or other efficiencies (such as improved ease of product recovery) are obtained.

Method of producing products by enzyme-catalyzed reactions in

An improved fermentation process for producing alcohol which includes the combination of vacuum fermentation and vacuum distillation. Preferably, the vacuum distillation is carried out in two phases, one a fermentor proper operated at atmospheric pressure and a flash phase operated at reduced pressure with recycle of fermentation brew having a reduced alcohol content to the fermentor, using vapor recompression heating of the flash-pot recycle stream to heat the flash-pot or the distillation step, and using 'water load balancing' (i.e., the molar ratio of water in the fermentor feed is the same as the molar ratio of water in the distillation overhead).
