Latest Patents

Guoliang Li holds a patent for a genetically engineered bacterium used for producing uridine with high yield. The patent describes a strain that heterologously expresses the pyrimidine nucleoside operon sequence pyrBCAKDFE on its genome, which is prompted by a strong promoter. This engineered strain reconstructs the pathway of uridine synthesis and overexpresses the autologous prsA gene coding for PRPP synthase. The strain also has deficiencies in several enzymes, allowing for efficient uridine production. The results show that the bacteria can yield 40-67 g/L of uridine in a 5 L fermentor after fermentation for 40-70 hours, achieving a maximum productivity of 0.15-0.25 g uridine per gram of glucose.
