Patents by Inventor Claus Christophersen

Claus Christophersen 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).

  • Method for production of maltose and a limit dextrin, the limit dextrin, and use of the limit dextrin
    Patent number: 6361809
    Abstract: In the method raw starch is treated with the amylase with the enzyme classification EC 3.21.133 below the gelatinization temperature, whereafter the maltose and the limit dextrin are recovered. The method is simple and cheap and gives rise to a maltose of high purity and to a cheap limit dextrin useable as a fat replacer in foods.
    Type: Grant
    Filed: April 9, 1996
    Date of Patent: March 26, 2002
    Assignee: Novozymes A/S
    Inventors: Claus Christophersen, Sven Pedersen, Tommy Rex Christensen
  • Enzyme with rhamnogalacturonase activity
    Patent number: 6033900
    Abstract: Animal feed compositions and methods for treating one or more of soy, pea or rape-seed, or other material derived from Fabales or Cruciferaceae, with an enzyme having rhamnogalacturonase activity, wherein the enzyme having rhamnogalacturonase activity cleaves a rhamnogalacturonan backbone to produce rhamnose as a non-reducing end (RGase II) or cleaves a rhamnogalaturonan backbone to produce galacturonic acid as a non-reducing end.
    Type: Grant

  • Enzyme with rhamnogalacturonase activity
    Patent number: 5882911
    Abstract: The present invention relates to DNA sequences encoding a rhamnogalacturonase which comprises(a) the DNA sequence of nucleotides 64-1587 of SEQ ID NO:1;(b) a DNA sequence which hybridizes to the same probe as nucleotides 64-1587 of SEQ ID NO:1 under conditions of presoaking in 5.times.SSC and prehybridizing for 1 hour at -40.degree. C. in a solution of 5.times.SSC, 5.times.Denhardt's solution, 50 mM sodium phosphate, pH 6.8, and 50 mg of denatured sonicated calf thymus DNA, followed by hybridization in the same solution supplemented with 50 .mu.Ci 32-P-dCTP labelled probe for 18 h at -40.degree. C., followed by washing three times in 2.times.SSC, 0.2% SDS at 40.degree. C. for 30 minutes; or(c) a DNA sequence encoding an amino acid sequence having amino acids 20-527 of the sequence of SEQ ID NO;2.

  • Enzyme with rhamnogalacturonase activity
    Patent number: 5811291
    Abstract: An enzyme exhibiting rhamnogalacturonase activity, capable of cleaving a rhamnogalacturonan backbone in such a manner that galacturonic acids are left as the non-reducing ends, and which exhibits activity on hairy regions from a soy bean material and/or on saponified hairy regions from a sugar beet material. The enzyme has the amino acid sequence of SEQ ID NO:2 and is encoded by the DNA sequence of SEQ ID NO:1.
