1 Dissolve ingredients (except carbonate, thiosulfate and vitamins) and sparge medium with 80% N2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic. Dispense medium under same gas atmosphere into anoxic Hungate-type tubes or serum vials to 30% volume and autoclave. Add thiosulfate and vitamins from sterile anoxic stock solutions prepared under 100% N2 gas and carbonate from a sterile anoxic stock solution prepared under 80% N2 and 20% CO2 gas mixture. Stock solutions of thiosulfate and vitamins should be sterilized by filtration. Adjust pH of complete medium to 7.5, if necessary.
2 After inoculation add sterile air in an amount equivalent to 1% (v/v) of the total volume of the culture vessel.
