Experiments

Describe the research, experiments, and protocols you used in your iGEM project. These should be detailed enough for another team to repeat your experiments.

Please remember to put all characterization and measurement data for your parts on the corresponding Registry part pages.

What should this page contain?

  • Rubber stoppers (2.5 cm tapering to 2 1/8 cm)
  • Titanium wire (~15cm per unit)
  • Carbon felt
  • Glass reference housing
  • Oxidized nickel wire + Small ~3 mm rubber stoppers
  • Large metal needles for sampling
  • 3 mL plastic syringe (to be cut to act as housing for a counter-electrode)
  • Small magnetic stir bars
  • Needles and syringes of various size (sterile)
Chemicals:
  • Carbon paste suspended in Xylene
  • M5 Minimal Media (100 Mm Hepes)
  • KCl, crystal
  • dH2O
  • Bacto Agar
  • Vitamins/Minerals
  • 200 mM Lactate
  • Spectinomycin Antibiotic
  • IPTG Inducer Stock
Bacterial strains:
  • Shewanella Oneidensis Δmtrb_GFP_mtrb (spec resistance)
