| 1 Dissolve dehydrated RCM medium (available from BD BBL, OXOID or MERCK) in distilled water and add 0.5 ml/l Na-resazurin solution (0.1% w/v), bring to the boil and cool to room temperature while sparging with 80% N2 and 20% CO2 gas mixture. Dispense medium under same gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave. Before use, add 1.0 g of sodium carbonate per liter medium from a sterile anoxic stock solution prepared under 80% N2 and 20% CO2 gas mixture. Check pH of medium after autoclaving and adjust pH to 6.8, if necessary. | |||||
