Patents by Inventor Yoram Kapulnik

Yoram Kapulnik has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method for removing soluble metals from an aqueous phase
    Patent number: 5876484
    Abstract: A process for the removal of metal ions from solution and means for effecting such removal are described. The process is based on the hydroponic growth of sunflowers, terrestrial turfgrasses and/or members of the family Brassicaceae in solutions containing one or more metal ions. Metal ions can be efficiently removed from solutions by passing these solutions through the root biomass of these terrestrial plants. Receptacles containing the plants are also part of the invention.
    Type: Grant
    Filed: May 17, 1995
    Date of Patent: March 2, 1999
    Assignee: Phytotech, Inc.
    Inventors: Ilya Raskin, Slavik Dushenkov, Yoram Kapulnik, Nanda P. B. A. Kumar
  • Phytorecovery of metals using seedlings
    Patent number: 5853576
    Abstract: Methods and systems for alleviating the environmental and health hazards associated with environmental contamination by metals are provided. Contained living or non-viable biomasses of metal-accumulating plant seedlings deplete the metal elements and compounds in metal-containing aqueous solutions. Concomitantly, the contained biomasses of plant seedlings accumulate the metal elements and compounds. The energy and nutrient stores of the seeds from which the seedlings develop are exploited to minimize the costs of remediating the metal-containing aqueous solutions.

    Date of Patent: December 29, 1998
    Assignee: Phytotech, Inc.
    Inventors: Yoram Kapulnik, Burt Ensley, Ilya Raskin
