Introduction
Johannes M Cornelissen is a notable inventor based in Vlaardingen, Netherlands. He has made significant contributions to the field of enzymatic detergents and bleaching compositions. With a total of 4 patents to his name, Cornelissen's work has advanced the effectiveness of cleaning products.
Latest Patents
One of his latest patents is an enzymatic detergent and bleaching composition containing a specific rDNA. This innovative composition features a bleaching system that surpasses the traditional sodium perborate/TAED system. It employs a lipase produced by cloning the gene from the fungus Humicola lanuginosa and expressing it in Aspergillus oryzae as a host. The lipase is utilized in a manner that provides a lipolytic enzyme activity ranging from 100 to 0.005 lipolytic units per milligram of the composition. Another significant patent relates to the use of a specific class of lipases in conjunction with strong bleaching agents in detergent compositions. This class includes fungal lipases from Humicola lanuginosa or Thermomyces lanuginosus, as well as bacterial lipases that exhibit a positive immunological cross-reaction with the antibody of the lipase produced by Chromobacter viscosum var. lipolyticum NRRL B-3673. The strong bleaching agents in this invention are more effective than the sodium perborate/TAED system, such as peracetic acid, or they produce a peracid more rapidly upon perhydrolysis.
