  • Patent number: 9114109
    Abstract: Described herein is the finding that a mutant form of human neuroglobin (H64L) with a stable five-coordinate geometry reduces nitrite to nitric oxide approximately 2000-times faster than the wild type neuroglobin. Five-coordinate neuroglobin is also capable of binding and releasing oxygen. Based on these findings, the use of five-coordinate neuroglobin as a blood substitute is described herein. Particularly provided is a method of replacing blood and/or increasing oxygen delivery to tissues in a subject by administering to the subject a therapeutically effective amount of neuroglobin with a stable five-coordinate geometry. In some cases, five-coordinate neuroglobin is administered in combination with another therapeutic agent or composition, such as a second blood replacement product (for example, a hemoglobin-based oxygen carrier), a blood product (such as red blood cells, serum or plasma) or whole blood.

  • Patent number: 9011843
    Abstract: Disclosed are alginate formulations that help protect digestive enzymes in the formulations from denaturation during passage through the acidic stomach environment, and from other sources, following ingestion. The formulation changes consistency to permit release of the enzymes in the less-acidic gut. They contain monovalent alginate salts (sodium, potassium and ammonium alginate) but are designed to not include significant quantities of compounds which would generate divalent ions and thereby convert the monovalent alginate to a divalent alginate when exposed to aqueous solution. A buffering agent that does not react with the digestive enzymes or the monovalent alginate, and which does not generate divalent ions on exposure to aqueous solution, can be included. A chelating agent which binds divalent ions may be administered with the formulation. Additionally, the formulation may be admixed with inert excipients suitable for oral delivery. It is preferable that the ingredients are dried before formulation.

  • Patent number: 8969032
    Abstract: The invention relates to a method and a system for obtaining biogas in two or more stages in a hydrolysis and a methane stage, wherein the hydrolysis of solid biogenic materials is performed in at least two percolators operated at offset times. Liquid hydrolyzate and CO2 rich hydrolysis gas, and then hydrolysis gas comprising methane thereby arises in the percolator. The liquid hydrolyzate is removed from the percolators, wherein part of the hydrolyzate is fed into the methane stage and the other part of the hydrolysis stage. In the methane stage, the hydrolyzate is converted to biogas and fermenting fluid. In the method according to the invention, the percolators are operated in a gas tight manner and hydrolysis gas is drawn off from the percolators, wherein the hydrolysis gas comprising methane is fed to an energy utilization and CO2 rich hydrolysis gas is used for purging a further percolator operated at an offset time.

  • Patent number: 8795995
    Abstract: A process for conversion of syngas to liquid products that serve as surface acting agents uses the gas stream at a relatively low pressure to eliminate the use of a compressor. The process uses a liquid stream as the primary energy input to a gas injector that intensely mixes gas and the liquid with reduced compression costs while the presence of the liquid product maintains the gas-liquid dispersion as it flows downward to build a static pressure head. The process lowers the required gas pressure by adjusting the elevation of the gas injector such that a conduit receives the gas-liquid dispersion from the outlet of the injector and confines it as it travels downward to enter the bottom of a column of liquid. The liquid product provides a surface acting agent that prolongs the creation and duration of microbubbles in the gas-liquid dispersion.

  • Patent number: 8673615
    Abstract: A process utilizing enhanced photosynthesis and photocatalysis to purify water and/or utilize CO2 on a large scale by growing biomass in reduced time and space in a closed, continuous-flow system. Added CO2 and balanced nutrients combine with light to increase the growth rate of autotrophic microalgae which require CO2 for growth and produce oxygen. Organic and inorganic compounds and chemical toxins are mineralized in photocatalysis using such produced oxygen, which are then absorbed (metabolized) in the microalgal biomass that is harvested.

  • Patent number: 8669083
    Abstract: An integrated system produces ethanol and biogas from raw plant materials. The system includes a pretreatment apparatus for converting raw plant materials into sugars and a fermenter for fermenting the sugars to produce a beer including ethanol. A distillation apparatus separates the beer into the ethanol and a whole stillage, and a separator then separates the whole stillage into a thin stillage and wet distillers grains. A biogas apparatus processes a first portion of the thin stillage to produce biogas and a biogas effluent, and converts a percentage of the non-fermentable solids and organic acids in the thin stillage into biogas. The pretreatment apparatus is supplied with an amount of fresh water and an amount of backset, the backset including the biogas effluent recycled from the biogas apparatus to the pretreatment apparatus.
