| 1 Dissolve ingredients (except vitamins), then sparge medium with 80% N2 and 20% CO2 gas mixture to make it anoxic and until a pH of 6.5 is reached. Dispense medium under same gas atmosphere into anoxic serum vials to 20% of their volume and autoclave. After autoclaving add vitamins from a sterile stock solution prepared under 100% N2 gas atmosphere and sterilized by filtration. Prior to inoculation add 5% (v/v) sterile H2 and 5% (v/v) sterile air to the headspace by using syringes. Check pH of the complete medium and adjust pH to 6.5, if necessary. Incubate without shaking. | |||||
| 2 Note: After growth has started cell density of the culture can be increased by replenishing H2 and air every two days. | |||||
