Abstract: Disclosed are methods for treating catmint oil. The treated catmint oil can be used for the production of hydrogenated catmint oil, which is enriched in the insect repellent, dihydronepetalactone.

Abstract: Methods are provided for treating production fluid in a production well in an oil reservoir to reduce the amount of sulfide in the production fluid. The production fluid is treated with nitrate and/or nitrite ions or inorganic oxidizing agent in an aqueous solution that is added to the well casing.

Abstract: A method to improve the effectiveness of MEOR or bioremediation processes. In this method toxic chemicals accumulated in subterranean sites adjacent to the water injection wells are either dispersed or removed prior to introduction of microbial inocula for enhanced microbial oil recovery or bioremediation of these sites.

Abstract: Methods are provided for treating production fluid in an oil reservoir to reduce the amount of sulfide in the production fluid. The production fluid is treated with nitrate and/or nitrite ions in an aqueous solution that is added to an injection well that is in contact with the production well.

Abstract: The present disclosure relates to isolation and identification of unique Pseudomonas stutzeri strains that can grow on crude oil under denitrifying conditions and are useful in oil recovery.

Abstract: Processes for producing polytrimethylene ether glycol and copolymers thereof are provided wherein, by condensing and recycling at least a portion of the vapor phase produced as the reaction progresses, the yield loss and polymer color are reduced.

Abstract: This invention provides processes for improved recovery of essential oil from the catmint (catnip) plant Nepeta cataria.

Abstract: A method to prevent contamination of feed line(s) and nutrient feed reservoirs(s) is disclosed. In this method the growth medium which flows from the nutrient feed reservoir through the feed line to the bioreactor contains at least one nutritional component supplied at a concentration which is inhibitory to cell growth. The inhibitory nutritional component in the growth medium prevents back growth of cells from the bioreactor into the feed line(s). The growth medium with inhibitory nutritional component is diluted prior to or at entering the bioreactor.

Abstract: Methods, microorganisms, and compositions are provided wherein oil reservoirs are inoculated with microorganisms belonging to Pseudomonas stutzeri and medium including an electron acceptor. The Pseudomonas stutzeri grow in the oil reservoir to form plugging biofilms that reduce permeability in areas of subterranean formations thereby increasing sweep efficiency, and thereby enhancing oil recovery.

Abstract: Methods, microorganisms, and compositions are provided wherein oil reservoirs are inoculated with microorganisms belonging to Arcobacter clade 1 and medium including an electron acceptor. The Arcobacter strains grow in the oil reservoir to form plugging biofilms that reduce permeability in areas of subterranean formations thereby increasing sweep efficiency, and thereby enhancing oil recovery.

Abstract: A process for the hydrogenation of a mixture of caryophyllenes by contact with hydrogen in the presence of a supported catalyst. The resulting products are useful for the application to skin.
