  3. rice

  4. How to solve

  5. Plasmid construction-1 RBS MT Cd p

  6. Catching E.coli has two merits

  7. Cd² ⁺ Cd² ⁺ Cd² ⁺ Catching E. coli is not weaken or is killed by absorbed cadmium. Cd² ⁺ Cd² ⁺ Cd² ⁺ Cd² ⁺

  8. Recyclable system of cadmium Cd² ⁺ Cd² ⁺ Cd² ⁺ Cd² ⁺ Cd² ⁺ Cd² ⁺

  9. We have constructed fusion protein RBS MT Cd p

  10. But we have problems

  11. E. coli may escape from cadmium by negative chemotaxis.

  12. Thanks for

  13. Modeling by UT-Tokyo

  14. Swarming assay E. coli E. coli E. coli go away from cadmium!!! Cd ddH2O

  15. If use only catching E. coli

  16. How to solve? Gathering to cadmium ion → Positive chemotaxis Positive chemotaxis factor → Aspartic acid(Asp)

  17. Go to Asp?

  18. E. coli Asp_concentration

  19. E. coli go to Asp!!!

  20. Using AspA OM IM fumafic acid aspartic acid ammonium ion RBS AspA Cd p

  21. Aspartic acid synthesis by Gathering E. coli − Cd 2+ + Cd 2+ 1 50 1 200 1 100 1 100 1 50 1

  22. Overview

  24. Remove LVA tag AspA LVA tag BBa_C0083
