  • Method of enhancing enzyme activity and enzyme solution having enhanced activity
    Patent number: 7892805
    Abstract: A method of enhancing the intrinsic activity of an enzyme in a raw enzyme solution, the method comprising treating the raw enzyme solution with an effective amount of a purifying agent, most preferably, activated carbon, to effect the enhancement and provide an enzyme solution of enhanced activity. Preferred enzymes are amylase, glucoamylase, cellulase, xylanase, and all other group 3 hydrolases.
    Type: Grant
    Filed: March 11, 2004
    Date of Patent: February 22, 2011
    Assignee: Immortazyme Company
    Inventors: Bradley A. Saville, Mikhail I. Khavkine
  • Enhancement of enzyme activity through purification and immobilization
    Patent number: 7312056
    Abstract: An improved method of making an immobilized enzyme comprising (a) treating an immobilization support with an aqueous solution comprising a cross-linking agent and polymeric aldehyde species and active centre species to produce a modified support; (b) isolating the modified support; (c) treating an enzyme solution with the modified support to produce the immobilized enzyme, the improvement comprising treating the aqueous solution of cross-linking agent with an effective amount of a purifying agent to reduce the amount of the polymeric aldehyde species and active centre species.
