3 Determining the collective efficacy of uric acid sensitive oxidation effect.

Figure 1

We introduced both systems, the Uric acid promoter and the catabolic enzyme, into E.coli nissle 1917, and simulated the conditions inside the gut.   conditions were:

•pH of 7

•The temperature of 37 degrees Celsius

•Hypoxia (hypoxic bag used)

•Add bile salts

•Pancreatic juice

•Liquid LB medium

•Adjust the uric acid concentration to 2000 μM.   Experimental Process:

Co-culture the bacteria with the above materials.

Co-incubate for 48 hours, incubate at 37°C on a shaker at 180 rpm

Test for uric acid concentration

Figure 2

The final degradation rate of the control group was about 10%, and the experimental group was about 45%, proving the functionality of our system.   In conclusion, we believe our system can be functional under the conditions of the intestine.
