| 1 Dissolve ingredients except carbonate, vitamins, cysteine and sulfide, then sparge medium with 80% H2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic. Add and dissolve carbonate, then dispense medium into anoxic Hungate-type tubes or serum vials to 30% of their volume under 80% H2 and 20% CO2 gas atmosphere and autoclave. Add vitamins (sterilized by filtration), cysteine and sulfide from sterile anoxic stock solutions prepared under 100% N2 gas. Prior to use check pH of complete medium and adjust to 5.8 - 6.0, if necessary. | |||||
| 2 Note: After growth has started and the culture is becoming turbid add sterile 80% H2 and 20% CO2 gas mixture to 0.5 - 1 bar overpressure. | |||||
