  • Patent number: 11808751
    Abstract: A system is provided for detecting the mass of oil in an inorganic mineral of shale. The system operates by performing an extraction test on a first shale sample by using chloroform to obtain a total content of shale oil in the shale; enriching kerogen from the second shale sample to obtain dry kerogen; and performing an extraction test on oven-dried kerogen by using chloroform to determine the mass of extracted kerogen. The system also operates by determining the mass of the oil in the organic matter of the shale sample and the mass of the oil in an inorganic mineral of the shale; establishing a model for predicting a ratio of the mass of the oil in the inorganic mineral of the shale to the mass of the oil in the organic matter; and using the prediction model to determine the mass of oil in an inorganic mineral.

    Abstract: The present invention is a system for optimizing production of biomass. The system contains one or more growth modules under a shading element that diffuses light. Each of the growth modules has a plurality of vertical growth columns arranged on a bottom manifold. The biomass is grown within a liquid growth medium held within each of the vertical growth columns until it reaches a desired growth. The biomass is then harvested through gravitational flow of the biomass and the liquid growth medium out of the bottom of each growth column. The bottom manifold collects gravitational flow of the biomass and liquid growth media from each growth column and aggregates the output of each individual column into a collective output of the growth module.

    Abstract: The present invention provides methods for catalyzing the conversion of an olefin to any compound containing one or more cyclopropane functional groups using heme enzymes. In certain aspects, the present invention provides a method for producing a cyclopropanation product comprising providing an olefinic substrate, a diazo reagent, and a heme enzyme; and admixing the components in a reaction for a time sufficient to produce a cyclopropanation product. In other aspects, the present invention provides heme enzymes including variants and fragments thereof that are capable of carrying out in vivo and in vitro olefin cyclopropanation reactions. Expression vectors and host cells expressing the heme enzymes are also provided by the present invention.

  • Publication number: 20150087042
    Abstract: The present invention provides genetically modified eukaryotic host cells that produce isoprenoid precursors or isoprenoid compounds. A subject genetically modified host cell comprises increased activity levels of one or more of mevalonate pathway enzymes, increased levels of prenyltransferase activity, and decreased levels of squalene synthase activity. Methods are provided for the production of an isoprenoid compound or an isoprenoid precursor in a subject genetically modified eukaryotic host cell. The methods generally involve culturing a subject genetically modified host cell under conditions that promote production of high levels of an isoprenoid or isoprenoid precursor compound.

  • Patent number: 8986948
    Abstract: The present invention relates to the use of nucleic acid molecules coding for a bacterial xylose isomerase (XI), preferably coming from Clostridium phytofermentans, for reaction/metabolization, particularly fermentation, of recombinant microorganisms of biomaterial containing xylose, and particularly for the production of bioalcohols, particularly bioethanol, by means of xylose fermenting yeasts. The present invention further relates to cells, particularly eukaryotic cells, which are transformed utilizing a nucleic acid expression construct which codes for a xylose isomerase, wherein the expression of the nucleic acid expression construct imparts to the cells the capability to directly isomerize xylose into xylulose. Said cells are preferably utilized for reaction/metabolization, particularly fermentation, of biomaterial containing xylose, and particularly for the production of bioalcohols, particularly bioethanol.
