  • Recombinant vector capable of increasing secretion of Koji mold protease
    Patent number: 7842799
    Abstract: To improve the activity of a Koji mold protease in a solid or liquid culture medium in the production of foods (e.g., a seasoning), pharmaceuticals (e.g., a digestive agent), protease for use in a detergent and the like. Disclosed are a recombinant vector having capability of increasing the secretion of the Koji mold protease, a Koji mold which is transformed with the vector and has an increased expression of a gene for a protease or an increase secretion of the same, a method for the production of a protease by using the transformed Koji mold, and the like.

  • DNA fragment containing a tannase gene, a recombinant plasmid, a process for producing tannase, and a promoter
    Patent number: 5665584
    Abstract: The present invention relates to a DNA fragment of 3,563 base pairs containing a gene coding for tannase and derived from a microorganism belonging to the genus Aspergillus, with the following restriction enzyme map: ##STR1## B: Bam HI, H: Hind III, K: Kpn I, S: Sal I, X: Xba I; a DNA fragment containing a tannase gene coding for the amino acid sequence of (SEQ ID NO:4); a recombinant plasmid comprising the DNA fragment containing the tannase gene inserted into a plasmid vector; a process for producing tannase, comprising culturing a microorganism belonging to the genus Aspergillus capable of producing tannase in medium with the recombinant plasmid, and recovering tannase from the culture; and a promoter represented by the nucleotide sequence of (SEQ ID NO:1). Tannase can be efficiently produced according to the present invention.
