  • Patent number: 10369604
    Abstract: A method of decontaminating soil and ground water containing organic contaminants and metal compounds. It comprises the steps of first treating such soils and ground water with an effective amount an aqueous solution containing a peroxide and a water soluble chelating agent for a time sufficient to have the water soluble chelating agent chelate at least one of the metals of the metal compounds present in the soil and ground water. Next, the chelated metals are brought into contact with the peroxide to catalytically convert the peroxide to an oxidizing agent and hydroxyl ion. The hydroxyl ion converts the halogenated organic compound into environmentally safe, non-toxic compounds. Gases that are produced from this reaction, and from the oxidation of organic compounds, are used to diffuse solution into the soil to chelate calcium and magnesium, thereby causing the sodium to be dislodged from the soil and reduce sodicity in the soil.

  • Patent number: 9822426
    Abstract: A process for bio-oxidation of sulfides in mineral ore having a metal such as gold occluded or dispersed within the ore as a sulfide is disclosed. The first step comminutes the ore into particles with a size distribution having a P80 of less than 0.25 inch with minus 106 micron particles in the range of 15% to 40% by weight. Agglomerates are formed by adding to the comminuted ore particles an acidic inoculate solution including water, with the solution further including microorganisms capable of bio-oxidizing the sulfides. The agglomerates are then placed in at least one bio-reactor containment vessel to form an ore bed. The process continues by bio-oxidizing the sulfides in the ore bed; then re-circulating the solution through the ore bed, and continuing the bio-oxidation until a desired bio-oxidation level is achieved. Thereafter, the metal is recovered from the ore.

  • Patent number: 8846377
    Abstract: A process for capturing CO2 includes contacting a CO2-containing gas with an absorption mixture optionally within a packed reactor is provided. The absorption mixture includes a liquid solution and micro-particles. The micro-particles include a support material and biocatalyst supported by the support material and are sized and provided in a concentration such that the absorption mixture flows through the packed reactor and that the micro-particles are carried with the liquid solution to promote dissolution and transformation of CO2 into bicarbonate and hydrogen ions. The absorption mixture and micro-particles may be provided in an absorption reactor so as to be pumpable. Furthermore, a process for desorbing CO2 gas from an ion-rich aqueous mixture includes providing biocatalytic micro-particles and feeding the mixture to a desorption reactor, to promote transformation of the bicarbonate and hydrogen ions into CO2 gas and water.

  • Patent number: 8846340
    Abstract: The present invention relates to non-catalytic carbohydrate-binding modules (CBM) belonging to a new family of CBM's. A CBM of the invention was found attached to a glycosyl hydrolase family 61 (GH61) polypeptide and was shown to have little homology with known CBM's indicating that it is the first known member of a new family of CBM's. The present invention further relates to CBM's preferably exhibiting binding affinity for cellulose; to a method of producing such CBM's; and to methods for using such CBM's in the textile, detergent and cellulose fiber processing industries, for purification of polypeptides, immobilization of active enzymes, baking, manufacturing of biofuel, modification of plant cell walls.
