Noriko Tsutsumi has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Lipolytic enzymes
    Publication number: 20020110854
    Abstract: The present invention relates to lipolytic enzymes and DNA sequences encoding same. More specifically, the present invention relates to the lipolytic enzyme and DNA encoding same isolated from Fusarium culmorum CBS 513.94 and analogues thereof.
    Type: Application

    Applicant: Novozymes A/S
    Inventor: Noriko Tsutsumi
  • Acidic phospholipase, production and methods using thereof
    Patent number: 6127137
    Abstract: An acidic phospholipase is obtained from a strain of the genus Hyphozyma. It is able to hydrolyze both fatty acyl groups in intact phospholipid. Advantageously, it has no lipase activity and is active at very low pH; these properties make it very suitable for use in oil degumming, as enzymatic and alkaline hydrolysis (saponification) of the oil can both be suppressed. The phospholipase is not membrane bound, making it suitable for commercial production and purification.
    Type: Grant
    Filed: April 20, 1999
    Date of Patent: October 3, 2000
    Assignee: Novo Nordisk A/S
    Inventors: Miyoko Hasida, Noriko Tsutsumi, Torben Halkier, Mary Ann Stringer
  • Starch conversion process
    Patent number: 6087149
    Abstract: The present invention relates to a starch conversion process of the type which includes a debranching step wherein an isoamylase being active at the process conditions prevailing is used for debranching the starch and to the use of thermostable isoamylases for starch conversion. The invention further relates to an isolated isoamylase obtained from a strain of the genus Rhodothermus and to cloned DNA sequences encoding isoamylases derived from a strain of Rhodothermus or Sulfolobus, to expression vectors comprising said DNA sequence, host cells comprising such expression vectors, and finally to methods for producing said isoamylases.
    Type: Grant
    Filed: August 4, 1998
    Date of Patent: July 11, 2000
    Assignee: Novo Nordisk A/S
    Inventors: Noriko Tsutsumi, Henrik Bisg.ang.rd-Frantzen, Allan Svendsen
  • Enzymatic detergent composition
    Patent number: 5929017
    Abstract: A lipolytic enzyme with high activity at alkaline pH in the absence of Ca.sup.++ can be obtained from strains of filamentous fungi belonging to the genus Absidia. The lipolytic enzymes are effective for improving the effect of detergents towards fatty soiling.
