In still another embodiment, the present invention can be used to separate, concentrate and/or purify any material, including biological products and/or biomaterials, that can be selectively bound to a binding agent, thereby yielding a complex that will readily partition onto bubble surfaces in a foam.Type: ApplicationFiled: April 28, 2006Publication date: January 8, 2009Applicant: THE UNIVERSITY OF AKRONInventors: Lu-Kwang Ju, Qin Zhang

Publication number: 20080296223Abstract: The invention provides compositions derived from brown-rot fungi that are suitable for use in bioremediation and similar applications where it is desirable to transform a target compound, often a toxic organic compound, into a different compound or compounds having more acceptable properties. The compositions are suitable for treating aqueous solutions or suspensions to reduce the amount of an undesired organic compound present, usually as one step in a treatment process to render the solution or suspension more suitable for environmental release. The invention also provides improved methods for growing fungal cultures for production of culture fluids.Type: ApplicationFiled: May 30, 2008Publication date: December 4, 2008Inventor: Bryan HIROMOTO

Publication number: 20080296222Abstract: A method of slurrifying oil contaminated materials by introducing a microemulsion or microemulsion-forming surfactant(s) to the material and subjecting the mixture to suitable shear or mixing forces to suitably blend such mixtures. The method may be applied directly to wastes such as waste drill mud cuttings and muds, emulsions, sludges, or soil substrates contaminated with water and/or oil drilling fluids in order to both reduce the viscosity and improve the lubricity, wetting, and flow properties of the substrate.Type: ApplicationFiled: November 7, 2005Publication date: December 4, 2008Applicant: SURFACTANT TECHNOLOGIES LIMITEDInventors: John Harrison, Mark Zwinderman

Patent number: RE41762Abstract: The present invention provides a nanostructured device comprising a substrate including nanotroughs therein; and a lipid bilayer suspended on or supported in the substrate. A separation method is also provided comprising the steps of supporting or suspending a lipid bilayer on a substrate; wherein the substrate comprises nanostructures and wherein the lipid bilayer comprises at least one membrane associated biomolecule; and applying a driving force to the lipid bilayer to separate the membrane associated biomolecule from the lipid bilayer and to drive the membrane associated biomolecule into the nanostructures.Type: GrantFiled: June 30, 2008Date of Patent: September 28, 2010Assignee: STC.UNMInventors: Gabriel P.
