1 Dissolve ingredients except bicarbonate, sodium thiosulfate, vitamins, and DTT. 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 under 80% H2 and 20% CO2 gas atmosphere and autoclave. Add thiosulfate, vitamins and DTT from anoxic stock solutions prepared under 100% N2 gas and sterilized by filtration. Prior to use check pH of completed medium and adjust to 6.0, if necessary. After inoculation add sterile 80% H2 and 20% CO2 gas mixture to 2 bar overpressure.
Solution occurs in 170 other media (first defined in Medium 141).
