| 1 Dissolve ingredients (except carbonate, yeast extract, malic acid, vitamins and cysteine) 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 and autoclave. Prior to inoculation add yeast extract, malic acid, vitamins (sterilized by filtration), and cysteine 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. The pH of the complete medium should be 6.2. | |||||
