    Date of Patent: July 13, 1999
    Assignee: Rohm Enzyme Finland OY
    Inventors: Richard B. Fagerstrom, Marja Paloheimo, Raija Lantto, Tarja Lahtinen, Pirkko Suominen
  • Patent number: 5834286
    Abstract: The present invention provides a recombinant combination strain which is capable of over-expressing at least two different genes under two separate promoters in filamentous fungi. The genes encode phytase and pH 2.5 acid phosphatase. Mixtures containing desired ratios of the two enzymes are prepared by recombinant DNA techniques. The enzyme mixtures show a cooperative effect in the degradation of phytic acid and its salts. The preferred ratios of the two enzymes are from about 3:1 to about 16:1.
    Type: Grant
    Filed: May 24, 1995
    Date of Patent: November 10, 1998
    Assignee: Rohm Enzyme Finland Oy
    Inventors: Helena K. M. Nevalainen, Marja T. Paloheimo, Richard B. Fagerstrom, Arja S. K. Miettinen-Oinonen, Marja K. Turunen, John A. Rambosek, Christopher S. Piddington, Christine S. Houston, Michael A. Cantrell
  • Patent number: 5830733
    Abstract: The present invention provides a nucleic acid molecule encoding a phytase. The present invention also provides a nucleic acid molecule encoding a pH 2.5 acid phosphatase. Also provided are vectors, host cells, and a method of overexpressing phytate degrading enzymes.
    Type: Grant
    Filed: March 1, 1996
    Date of Patent: November 3, 1998
