Wouter Adrianus Van Winden 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).

  • Fermentation method for producing gellan gum
    Patent number: 11149293
    Abstract: This invention provides a fermentation method of producing gellan gum, wherein a certain amount of fermentation broth is retained in the fermentor as a seed for next batch fermentation or transferred to another fermentor as a seed for next batch fermentation in that fermentor. The fermentation method of this invention reduces fermentation cost of gellan gum and lowers contamination risk during seed cultivation.
    Type: Grant

  • Nitrogen source feeding fermentation process for producing gellan gum
    Patent number: 10767206
    Abstract: The invention provides a new fermentation process for producing gellan gum, which can control the feeding amount and feeding speed of the nitrogen sources accurately and quantitatively, and control the growth and gum production of the strains, so as to significantly improve the controllability, stability and yield of the fermentation process for producing gellan gum.
