Preparation
- Dissolve ingredients except sulfur, meat extract and sulfide, adjust pH to 5.0 - 5.5 with 2 N H2SO4 and sparge medium with 80% H2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic. Distribute medium under the same gas atmosphere into anoxic Hungate-type tubes or serum vials already containing the appropriate amount of sulfur, only to 30% of their volume to allow for a large head space. For sterilization heat cultivation vessels in boiling water for 1 -2 hours on each of 3 successive days. Add meat extract and sulfide from sterile anoxic stock solutions prepared under 100% N2 gas atmosphere.
- After inoculation pressurize the vessels with sterile 80% H2 and 20% CO2 gas mixture to 2 bar overpressure.
