| abstract |
The present invention provides a method for producing an amino sugar selected from the group consisting of N-acetylglucosamine, glucosamine, or a combination thereof. The method comprises culturing a yeast in a culture medium and recovering N-acetylglucosamine, glucosamine, or a combination thereof, wherein the yeast comprises an exogenous nucleic acid sequence encoding glucosamine-6-phosphate synthase operably linked to a promoter. The invention also provides a genetically modified yeast that produces an amino sugar selected from the group consisting of N-acetylglucosamine, glucosamine, or a combination thereof. |
