PEPTIDOGLYCAN HYDROLASE ANTIMICROBIALS FOR ERADICATING LACTOBACILLI THAT CONTAMINATE AND REDUCE ETHANOL YIELDS IN BIOFUEL FERMENTATIONS

Suppressing microbial contamination is a major challenge in ethanol fermentation processing.  This invention describes a non-antibiotic source of antimicrobials for preventing or eradicating lactobacilli contaminants in the ethanol fermentation processing.  The invention involves purified recombinant proteins from expressed endolysin genes that when exposed to the target bacteria demonstrate lytic activity.

INHIBITOR TOLERANT SACCHAROMYCES CEREVISIAE STRAIN

Furfural and 5-hydroxymethylfurfural (MHF) are representative inhibitors to ethanologenic yeast generated from biomass pretreatment using dilute acid hydrolysis.  Few yeast strains tolerant to inhibitors are available.

A NEW TOLERANT YEAST PRODUCING BETA-GLUCOSIDASE FOR LOW-COST CELLULOSIC ETHANOL PRODUCTION USING SSF

The USDA developed a new yeast that naturally produces beta-glucosidase and ethanol so no beta-glucosidase needs to be added to complete a one-step simultaneous saccharification and fermentation (SSF) for cellulosic ethanol production.

55.11

 ETHERS AS RENEWABLE OILS, GREASES, AND LIQUID FUELS

The invention is a method for converting renewable, agriculture-based sugars and polyols (alcohols) into their corresponding methyl and/or ethyl ethers.

265.12

METHODS FOR PRODUCING BIO-OIL

The invention involves methods for producing bio-oil from a feedstock (e.g., lignocellulosic) involving (1) pyrolyzing the feedstock in an inert atmosphere in a reactor to produce bio-oil, bio-char and non-condensable gases; (2) recycling about 10 to about 99% of the non-condensable gases to the reactor to produce deoxygenated bio-oil; wherein the method is conducted in the absence of oxygen and wherein the method does not utilize externally added catalysts.

SPIRAL-WOUND LIQUID MEMBRANE MODULE FOR SEPARATION OF FLUIDS AND GASES

The present invention is a filtering and chemical separation device that performs the operations of solvent extraction and pervaporation in a single piece of equipment, configured as a spiral-wound membrane module, and provides for the replenishment of the solvent in the supported liquid membrane while the module continues in operation.  It provides a solution to the problem of separating miscible compounds efficiently and with low energy requirements.
