Important Protocols
Glycerol Stock Preparation
- 1. Inoculated TSB with MR-1 (either from plate or glycerol stock) and grow overnight.
- 2. add glycerol to culture to final concentration of 80% glycerol.
- 3. place 1ml in 1.5ml freezer safe eppendorf tubes (do not fill eppendorfs with more than 1ml to allow for expansion by freezing).
Microbial Fuel Cell Assembly
- 1. cut two 3 inch clear PVC tubes .
- 2. sandwich them with nafion cation exchange membrane between them.
- 3. add caulking around both sides of membrane-tube junction.
- 4. let dry for 15 minutes.
- 5. repeat step 3 and 4.
- 6. cut off excess membrane around junction.
- 7. add one more layer to seal up junction.
- 8. let dry overnight.
- 9. cut 2.5in-3in x 12in of carbon cloth
- 10. roll around tip of finger.
- 11. weave titanium wire close to end edge of roll.
- 12 fold titanium wire up the length of the roll.
- 13. twist excess wire around itself.
- 14. cut wire at .5in-1in.
- 15. push through stopper.
- 16. seal hole from wire with caulking.
- 17. let dry overnight. (two of these make up the cathode and the anode)
- 18. pour potassium ferricyanide in one chamber of the cell.
- 19. carefully push stopper with carbon cloth to plug the chamber.
- 20. push hollow needle through stopper to let air out of chamber.
- 21. pour overnight culture of MR-1 into other chamber.
- 22. place glass slide in chamber.
- 23. carefully push stopper with carbon cloth to plug the chamber.
- 24. push new sterile hollow needle in stopper into air bubble in chamber to let out any CO2 bacteria will produce.
- 25. open ExcelINX up on computer.
- 26. connect electrodes from DMM to cathode and anode (remember which channels are being used).
- 27. start ExcelINX.
