Abstract: Ear corn is picked from corn fields by ear corn harvesters and transported to a central shelling station associated with an ethanol manufacturing facility. Shelled corn from the central shelling station is processed into ethanol at the ethanol manufacturing facility, and corn cobs from the central shelling station are burned to provide process heat for the ethanol manufacturing process. Energy is conserved and costs are reduced during the picking and shelling of the ear corn and by the burning of cobs for process heat.
Abstract: It has surprisingly been discovered that it is possible to use enzymes in deep eutectic solvents (DES). DES's are mixtures of a nitrogen salt or a metal salt and a strong hydrogen bond donor that can be mixed in proportions that form a eutectic point.

Abstract: 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.
Abstract: 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.
Abstract: Dissolution, partial dissolution or softening of cellulose in an ionic liquid (IL) and its subsequent contact with anti-solvent produces regenerated cellulose more amorphous in structure than native cellulose, which can be separated from the IL/anti-solvent mixture by mechanical means such as simple filtration or centrifugation. This altered morphology of IL-treated cellulose allows a greater number of sites for enzyme adsorption with a subsequent enhancement of its saccharification. The IL-treated cellulose exhibits significantly improved hydrolysis kinetics with optically transparent solutions formed after about two hours of reaction. This provides an opportunity for separation of products from the catalyst (enzyme) easing enzyme recovery. With an appropriate selection of enzymes, initial hydrolysis rates for IL-treated cellulose were up to two orders of magnitude greater than those of untreated cellulose.

Abstract: Systems and methods for hydroponically growing microorganisms within a self-contained air-supported structure, in which microorganisms are grown in an organic slurry, harvested, and processed to obtain and process and distribute molecules useful for biofuel or other purposes.
Abstract: An immobilization carrier containing an electron acceptor compound is used in addition to glutaraldehyde and poly-L-lysine to immobilize an enzyme and an electron acceptor compound simultaneously to an electrode. For example, here are used diaphorase as the enzyme and 2-amino-3-carboxy-1, 4-naphthoquinone (ACNQ) as the electron acceptor compound.
Abstract: A process for producing ethanol including a combination of biochemical and synthetic conversions results in high yield ethanol production with concurrent production of high value coproducts. An acetic acid intermediate is produced from carbohydrates, such as corn, using enzymatic milling and fermentation steps, followed by conversion of the acetic acid into ethanol using esterification and hydrogenation reactions. Coproducts can include corn oil, and high protein animal feed containing the biomass produced in the fermentation.
Abstract: The present invention relates to a process for obtaining fuel ethanol by using agricultural and agroindustrial waste materials composed of lignocellulose, and especially sugar cane bagasse. These residues have significant contents of carbohydrates in the form of polysaccharides (cellulose and hemicellulose), which can be hydrolyzed by chemical and enzymic processes. The hemicellulose fraction is submitted to mild hydrolysis with sulphuric acid, and the solid material from this hydrolysis is submitted to a process of saccharification (enzymic hydrolysis) with simultaneous rapid alcoholic fermentation under conditions which allow a significant increase in conversion to alcohol in a greatly shortened time.

Abstract: A method and apparatus is provided for microbial seeding and amendment of traditional alternative fuels production systems and processes using immobilized microbe bioreactors. The system addition utilizes attachment of yeast or other microbial consortia to a substrate to enhance alternative fuels production in fermentation processes. The system allows for the maintenance of a constant concentrated microbial population, thus enhancing alternative fuels production by stabilizing microbial populations. Desired aerobic and anaerobic conditions are maintained using a microbubble aeration device coupled to the Immobilized Microbe Bioreactor (IMBR) seeding reactors. Generation of the microbial populations for seeding requires control of aerobic and anaerobic conditions to ensure growth of a microbial population acclimated to elevated alternative fuels concentrations.
