1 Dissolve ingredients except bicarbonate, vitamins, cysteine and sulfide. Sparge medium with 80% H2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic. Add and dissolve bicarbonate, then dispense medium into anoxic tubes 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 6.0, if necessary. | |||||
2 After inoculation add sterile 80% H2 and 20% CO2 gas mixture to 2 bar overpressure. |
