E.coli strain,senders:JW1908,BBa_T9002:JW1908,37°C.All measurements are averages from three replicate cultures with error bars representing standard deviations.
- Fig. 1,Fig. 2
- Results
- Green fluorescence intensity didn't increase in the culture containing BBa_K0840010(plac+CinI+LVA).We thought BBa_K084010 didn't work properly or LuxR gene didn't interact with signal molecules synthesized by BBa_K084010.
- Others responded at the same time(4 hours after induction).Final fluorescence intensity differd.

- Fig. 3
- Results
- Response time and final fluorescence intensity showed no significant difference.
- Discussion
- We thought AHL concentration was quickly reached the threshold concentration.The fluorescence intensity increased as gfp maturured.
- Fig. 4
- Results
- No significant difference in fluorescence intensity between the culture containing BBa_K084007(plac+RhlI) gene transformed cells and the culture containing BBa_K084008(plac+RhlI(LVA)) gene transformed cells.
- Discussion
- We thought that the rate of AHL synthesis by each autoinducer synthase was much faster than the rate of its degradation by protease.

- Fig.7
- Results
- No significant difference in fluorescence intensity between the culture containing BBa_K084007(plac+RhlI) gene transformed cells and the culture containing BBa_K084008(plac+RhlI(LVA)) gene transformed cells.
- Discussion
- We thought that the rate of AHL synthesis by each autoinducer synthase was much faster than the rate of its degradation by protease.

- Fig.9
- Results
- The final fluorescence intensity of the culture containing BBa_K084008 transformed cells which express LVA-tagged RhlI protein was lower than the culture containing cells which express untagged RhlI protein.It shows that LVA-tagged RhlI protein was degraded by LVA-specific protase.However,fluorescence intensity of both cultures increased at the same time.
- Discussion
- We thought it was because the AHL concentration was quickly reached the threshold concentration and cells began to express gfp.After 2 hours,fluorescence intensity started to increase.
