  • Cloning and expression of microbial phytase
    Publication number: 20030119163
    Abstract: A nucleotide sequence encoding phytase has been isolated and cloned. The coding sequence has been inserted into an expression construct which in turn has been inserted into a vector capable of transforming a microbial expression host. The transformed microbial hosts may be used to economically produce phytase on an industrial scale. The phytase produced via the present invention may be used in a variety of processes requiring the conversion of phytate to inositol and inorganic phosphate.
    Type: Application
    Filed: February 19, 2002
    Publication date: June 26, 2003
    Inventors: Robert F.M. Van Gorcom, Willem Van Hartingsveldt, Petrus Andreas Van Paridon, Annemarie Eveline Veenstra, Rudolf G.M. Luiten, Gerardus C.M. Selten
