1 Dissolve ingredients except carbonate, maltose and DTT, then sparge medium with 100% N2 gas for 30 - 45 min to make it anoxic. Dispense medium under same gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave at 121°C for 20 minutes. Add maltose and DTT from sterile anoxic stock solutions prepared under 100% N2 gas and sterilized by filtration and carbonate from a sterile stock solution prepared under 80% N2 and 20% CO2 gas atmosphere. Check pH of complete medium and adjust to 7.4, if necessary. |
