  • Publication number: 20040180424
    Abstract: Disclosed herein is a method for treating odors in wastewater treatment bodies. The pH of the body is preferably established above about 6 and most preferably above about 7, usually by adding a base to the body. The oxidation reduction potential of the body is established at about −300 mV or higher and more preferably about −200 mV or higher, usually by adding an oxidizing agent such as oxygen or nitrates. After these conditions are established, sulfur oxidizing bacteria are added to the body. These preferably include Paracoccus denitrificans (formerly called Thiosphaera pantotropha) ATTC number 35,512. The sulfur oxidizing bacterial population should be established at levels of at least about 1×104 cfu/mL and more preferably at levels of 1×105 to 1×106 cfu/mL or higher. The increased ORP and pH levels make sulfate reduction thermodynamically unfavorable.

These bacteria strains are unique among PAH-degrading bacterial strains because they form endospores and therefore can survive adverse environmental conditions. Among the strains presented are several from “P. naphthalenovorans”, a newly described species and also P. validus. Also presented are compositions for bioremediation comprising the bacterial strains of the invention and a method for isolating the strains and a method for using the strains for bioremediation.

  • Patent number: 6465240
    Abstract: A method is provided for treating a waste stream by contacting the waste stream sequentially with a consortium of prokaryotic microorganisms, preferably purple non-sulfur bacteria, followed by a the green algae Chlorella. The consortium of prokaryotic microorganisms assimilate a first portion of the wastes, and the green algae assimilate the remaining portion of the wastes to produce a substantially purified effluent stream. Isolated microorganisms made by the above method are valuable commercial products.

  • Patent number: 6461859
    Abstract: The invention relates to a method of removing thiophenic and organosulfide compounds from a fossil fuel comprising the steps of contacting the fossil fuel with hemoproteins, which oxidize the sulfur containing compounds to sulfoxides and sulfones in a reaction system containing organic solvent or not, and followed by a distillation step in which sulfoxides and sulfones are removed from the fuel. Preferred biocatalysts include hemoproteins such as chloroperoxidase from Caldariomyces fumago, and peroxidases and cytochromes from animal, plant or microbial cells. The hemoprotein biocatalyst can be contacted with the fossil fuel in free or immobilized forms. The reaction can be carried out in the presence of the fuel alone or with addition of any organic solvent. The biocatalytically oxidized fuel is then distilled in order to eliminate the heavy fraction which contains most of oxidized organosulfur compounds.

  • Patent number: 6432682
    Abstract: A process for producing a substance KF-1040A represented by formula (I), and another substance KF-1040B represented by formula (II), which comprises culturing microorganisms capable of producing the substances KF-1040A and KF-1040B, thus accumulating these KF-1040A and/or KF-1040B in the liquid culture and harvesting the same from the culture. Because of the activities of inhibiting diacyloglycerol transferase and sphingomyelinase, the above substances are useful in preventing and treating arteriosclerosis, obesity, thrombus, inflammation and immune function-related diseases.

  • Patent number: 6413763
    Abstract: A method for removing a gas compound from a site comprising placing cells having gas vesicles under conditions that induce the cells to float to a surface of an aqueous medium, harvesting the cells from the surface of the medium, lysing the cells, separating the gas vesicles from the lysed cells, crosslinking the gas vesicles with a crosslinking agent, loading a gas with a lowered partial pressure for the gas compound to be removed into the gas vesicles, and placing the gas vesicles contacted with a medium such that the gas compound is removed from the site to the medium. Harvesting gas-vesicle-containing cells is achieved by placing the cells under conditions that induce the cells to rise to the surface of an aqueous medium. Then collecting the cells from the surface of the medium. Gas vesicles are isolated by lysing the cells and separating the gas vesicles from the lysate. Once the gas vesicles are isolated, they can be modified, such as by crosslinking with glutaraldehyde.
