Patents Assigned to Petiva Private Limited
  • Polynucleotide for recombinant expression of sucrose isomerase
    Patent number: 9885030
    Abstract: The present invention is directed towards genetic modification of native gene encoding for sucrose isomerase and isomaltulose synthase to substantially increase the expression level of these enzymes and use of said enzymes in a process to produce rare disaccharides such as isomaltulose and trehalulose. Also disclosed in the present invention is expression constructs comprising the modified genes and a host cells to express the same.
    Type: Grant

    Inventors: Samir Kumar Roy, Saravanakumar Iyappan, Saju Varghese, Aparna Devi Addala, Milky Agarwal, Kanumuru Rahul Raju, Banibrata Pandey
  • Method of production of monosaccharides
    Patent number: 9752170
    Abstract: The present invention is directed towards genetic modification of native gene encoding for D-tagatose 3-epimerase and rhamnose isomerase to substantially increase the expression level of these enzymes and use of the enzymes in a process to produce rare monosaccharides such as psicose and allose. Also disclosed in the present invention is expression constructs comprising the modified genes and a host cells to express the same.
