Microbial Reduction of Furfurals to Furan Alcohols by a Microbial Species An ORNL researcher developed a method for producing furfuryl alcohol (FA) through bioprocessing using a thermophilic microorganism. This organism has been shown to be highly resistant to the toxic effects of furfural and hydroxymethylfurfural (HMF) and can propagate in the presence of over 48 g/L (500 mM) of furfural. The…

Electro-Fermentation Disclosure Number 201403323 Technology Summary Current pathways to generate biofuels either ferment sugars derived from biomass or convert them to a partially- oxygenated intermediate to be reduced to higher density fuels. The energy density and yield of a biofuel product is limited by the oxygen content of the feedstock, the metabolic capability of the organism a…

Genetically Modified Microorganisms with Enhanced Resistance to Acetate Efficient conversion of lignocellulose to alternative fuels is hindered by the difficulty of breaking down plant biomass. Pretreatment of materials is a necessary part of the production process; but during pretreatment, chemicals such as acetate form and inhibit or even stop fermentation. To address this challenge, ORNL resea…

Cofermentation with Cooperative Microorganisms for More Efficient Biomass Conversion It is well known that biomass has primarily two sources of fermentable carbohydrates, cellulose and hemicelluloses. Research has been underway for decades aimed at both depolymerizing these complex carbohydrates and fermenting them to products of interest such as fuels and chemicals. Common approaches are the a…

Improved Properties of Nanomaterials Using Complementary NanoFermentation Technique Improved Properties of Nanomaterials Using Complementary NanoFermentation Technique Disclosure Number 201503497 Technology Summary One synthetic platform technologies for nanomaterials at ORNL, NanoFermentation (NF) , can be defined as A biomineralization process using microbial activity (respiration …

Caloramator sp. Tolerance of Pretreatment Inhibitors from Lignocellulosics ORNL inventors discovered a novel microorganism that displays exceptional tolerance to several growth inhibitors generated during dilute acid pretreatment of lignocellulosic biomass. Vanillin, furfural, hydroxymethylfurfural and lignin are known to inhibit the growth of microorganisms, such as yeast, during fermentation of…

Catalytic Conversion of Bioethanol to Hydrocarbons A method for catalytically converting an alcohol to a hydrocarbon without requiring purified or concentrated alcohol was invented by ORNL researchers. This approach can be used for relatively dilute bio-mass produced alcohols, such as those found in a biomass fermentation reactor. Conventional biomass to hydrocarbon conversion is generally not c…

Microorganisms to Speed Production of Biofuels Researchers at ORNL developed microorganisms that can quickly overcome the resistance of biomass to breakdown, and improved both the cost and efficiency of the biofuel conversion process. Conventional biomass pretreatment methods release sugars, weak acids, and metabolic by-products that slow down or even stop fermentation, resulting in slower biofu…

Thermophilic Microorganism Host for Production of Industrial Solvents Thermophilic Microorganism Host for Production of Industrial Solvents Disclosure Number 200201059 Technology Summary The subject invention disclosed herein is a facultative microorganism isolated from goat manure capable of high growth rates at 55?C, pH 5, and tolerant of the presence …

Bacterial Fermentation Improves Metallic, Semiconducting Nanoparticle Production A team of researchers at ORNL has successfully developed a method for producing inorganic nanoparticles, and controlling their size and shape, using a bacterial fermentation process that employs chemicals to control bacterial synthesis. They subsequently built on that research by producing in large quantities semicon…
