| 1 Dissolve ingredients except sulfur, cysteine and sulfide. Sparge medium with 100% N2 gas for at least 30 - 45 min to make it anoxic and adjust pH to 6.0 with NaOH. Distribute the medium under 100% N2 gas atmosphere into anoxic Hungate-type tubes or serum vials which contain already the appropriate amount of sulfur. For sterilization heat the cultivation vessels containing medium plus sulfur in boiling water for 2 - 3 hours on each of 3 successive days! Prior to inoculation add cysteine and sulfide and from sterile anoxic stock solutions prepared under 100% N2 gas. | |||||
| 2 After inoculation pressurize tubes to 2 bar overpressure with sterile 100% N2 gas. | |||||
