Enhancement of farnesol resistance

Fig. 13: Colony formation efficiencies of E. coli JM109 engineered with marA on geraniol overlaid plates.
E. coli JM109 and E. coli JM109 (marA) were spotted on LBGMg agar plates in serial ten-fold dilutions (10⁻¹～10⁻6), overlaid with 30.0 % (v/v)　fanesol hexane solution (farnesol solution), and incubated at 30°C for 24 h. This figure shows that E. coli JM109 (marA) cells that overexpress the marA product is more survived on 30.0 % farnesol solution overlay plates than the counterpart control E. coli JM109 wild type cells.

Here you can describe the results of your project and your future plans. What should this page contain? Clearly and objectively describe the results of your work. Future plans for the project Considerations for replicating the experiments Project Achievements You can also include a list of bullet points (and links) of the successes and failures you have had over your summer. It is a quick reference page for the judges to see what you achieved during your summer. A list of linked bullet points of the successful results during your project A list of linked bullet points of the unsuccessful results during your project. This is about being scientifically honest.

-Time interval for treatment was set every 1 hour from 1 hour to 4 hours. A: ''E. coli'' JM109 (WT) + hexane; B: ''E. coli'' JM109 (''marA'') + hexane; C: ''E. coli'' JM109 (WT) + 0.5 % geraniol solution; D: ''E. coli'' JM109 (''marA'') + 0.5 % geraniol solution. As shown in Figs. 14 A and B, treatment with hexane of ''E. coli'' JM109 (WT) and of ''E. coli'' JM109 (''marA'') showed similar colony numbers during these treatment intervals to those of time zero. This result suggests that hexane at this concentration and duration of time for 4hours did not affect both cell growth. In contrast, treatment with geraniol of ''E. coli'' JM109 (WT) and of ''E. coli'' JM109 (''marA'') showed toxicities to both strains (Figs. 14 B, C and D). If we watch the colony numbers carefully, ''E. coli'' JM109 (''marA'') had more than ''E. coli'' JM109 (WT) during these treatment intervals ((Figs. 14 C and D). These results demonstrate that toxicity of the geraniol was less to the strain ''E. coli'' JM109 (''marA'') than the strain ''E. coli'' JM109 (WT).]]
