Latest Patents

Cheng’s listed patent is titled “Exopolysaccharide and Method for Preparing and Use Thereof.” It describes a process for producing and purifying an exopolysaccharide from the GJ-22 strain.

The method begins by fermenting a seed solution in a fermentation medium to obtain a fermentation broth. The broth is centrifuged, and the supernatant is filtered and treated with alcohol to precipitate crude polysaccharide. Proteins and small molecules are then removed through enzymatic treatment, the Sevag method, and dialysis. Finally, the polysaccharide sample is purified using an anion-exchange column and a molecular-exclusion chromatography column.
