| 1 Note: If the medium is being used without overpressure then adjust pH with a small amount of sterile anoxic 1 N HCl, if necessary. | |||||
| 2 Dissolve ingredients (except bicarbonate, vitamins, cysteine and sulfide), sparge medium with 80% H2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic. Add and dissolve bicarbonate and adjust pH to 6.5, then dispense medium under 80% H2 and 20% CO2 gas atmosphere into anoxic Hungate-type tubes or serum vials to 30% of their volume and autoclave. After sterilization add cysteine and sulfide from sterile anoxic stock solutions autoclaved under 100% N2 gas. Vitamins are prepared under 100% N2 gas atmosphere and sterilized by filtration. Adjust pH of complete medium to 6.8 - 7.0, if necessary. | |||||
| 3 For incubation use sterile 80% H2 and 20% CO2 gas mixture at two atmospheres of pressure. | |||||
