Patent number: 8921088Abstract: The present invention includes a method for harvesting or separating one or more biological cells from an aqueous feed, a stream, a suspension, or any combinations thereof by providing the aqueous feed, the stream, or the suspension comprising the one or more biological cells in a tank or a vessel; providing one or more ion-exchange resins, wherein the ion-exchange resin is an anion-exchange resin; contacting the anion-exchange resin with the aqueous feed; binding the one or more biological cells to the anion-exchange resin; releasing or eluting the bound one or more biological cells by changing the pH; and collecting the released one or more biological cells to obtain a concentrated slurry or suspension of the one or more biological cells.Type: GrantFiled: October 3, 2012Date of Patent: December 30, 2014Assignee: Board of Regents, The University of Texas SystemInventors: Martin Poenie, Jessica Jones

Patent number: 8617396Abstract: The development and application of a novel non-polar oil recovery process utilizing a non-dispersive solvent extraction method to coalesce and recover oil from a bio-cellular aqueous slurry is described herein. The process could apply to recovery of algal oil from a lysed or non-lysed algae slurry, recovery of Omega fatty acids from a bio-cellular aqueous feed, recovery of Beta-carotene from a bio-cellular aqueous feed and for the removal from produced water in oil production and similar type applications. The technique of the present invention utilizes a microporous hollow fiber (MHF) membrane contactor. The non-polar oil recovery process described herein can be coupled to a collecting fluid (a non-polar solvent such as heptane, a biodiesel mixture or the previously extracted oil) that is circulated through the hollow fiber membrane. In cases where the biodiesel mixture or the previously extracted oil is used the solvent recovery step (e.g. distillation) can be eliminated.Type: GrantFiled: October 24, 2011Date of Patent: December 31, 2013Assignees: Board of Regents, The University of Texas System, Organic Fuels Algae Technologies, LLCInventors: Peter B. Kipp, Rhykka Connelly, Frank Seibert, Martin Poenie, Robert E. Hebner, Michael D. Werst, Robert Pearsall, Lynn E. Katz, Kerry A. Kinney

Patent number: 8329449Abstract: A reverse phase extraction method for the recovery of triglycerides from aqueous slurries of algae is described herein. The present invention discloses the use of immobilized anion exchange and lipid binding resins. As the algae flows past the resin, triglycerides adhere while the bulk of the algae flows through. The lipids, useful for generating biofuels are then are eluted off the resin. The method of the present invention does not require prior drying of the algae, is inexpensive, and does not destroy the algal biomass which can be used for other purposes.Type: GrantFiled: October 13, 2010Date of Patent: December 11, 2012Assignee: Board of Regents, The University of Texas SystemInventors: Martin Poenie, Jessica Jones, James Beach
