Preparation

  1. Mix components thoroughly, except agarose, and adjust pH to 6.7.
  2. Add agarose to the medium and autoclave under a N2 gas atmosphere.
  3. After cooling to 50C, add the following solutions to the medium aseptically and anaerobically (autoclaved or *filter-sterilized).
  4. Keep the medium temperature at 50 C until the medium is distributed into sterile screw-capped test tubes as described below: Adjust pH to 7.0 with sterile HCl or NaOH solution.
  5. Dispense the medium to sterile screw-capped test tubes (typically 11 ml medium into sterile Hungate tubes) under air and cap.
  6. Allow to stand until the medium is solidified and a O2-gradient formed (as evidenced by a pink upper oxic zone and a colorless lower anoxic zone).
  7. Inoculate cells just below the pink-colorless interface in the medium tube using a syringe.
  8. Comment: The medium tubes can be stocked under a N2 gas atmosphere.
  9. In this case, prior to use, fill the head space with air and allow to stand until the O2 gradient is formed.
