Guglielmo M. Bisso 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).

  • Process for the continuous production of fructose-1,6-di-phosphate by employ of immobilized yeast
    Patent number: 4920049
    Abstract: The process provides the enzymatic phosphorylation of glucose to FDP by means of yeast immobilized by glutaraldehyde and the separation of FDP by ultrafiltration. A suspension of glutaraldehyde-treated yeast is fed to a fermenter, with addition of a nutrient mixture consisting of dextrose (1M), sodium phosphate (0.5 M), magnesium chloride (10 mM) and phosphoric acid until pH 6.5. The mixture is re-circulated through a hollow fiber ultrafiltration unit to separate the FDP that forms during the phosphorylation reaction.
    Type: Grant

  • Process for the preparation of fructose 1,6 diphosphate acid
    Patent number: 4575549
    Abstract: The process according to the invention provides, for the purification of FDPH.sub.4 -containing solutions, for a double chromatography combined with the molecular filtration.There are thus obtained concentrated and highly pure solutions containing fructose 1,6 diphosphate acid, which are perfectly suitable to be employed for the preparation of FDP and its salts.
