Preparation

  1. Mix ingredients except for yeast extract, bicarbonate, vitamin, thiamine, cyanocobalamin, and sulfide solutions.
  2. Dispense the medium into culture vessels under a stream of N2/CO2 (80/20) and seal with butyl rubber stoppers.
  3. Autoclave at 121 C for 15 minutes.
  4. Aseptically and anaerobically add the remaining ingredients using sterile syringes.
  5. Adjust pH to 7.0-7.3 using a compact pH meter.
