1 Dissolve ingredients (except carbonate, vitamins, pyruvate, yeast extract and reducing agents) 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. Add vitamins, pyruvate, yeast extract, cysteine and sulfide 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 atmosphere. Stock solutions of vitamins and pyruvate should be sterilized by filtration. The pH of the complete medium should be 7.0.
2 Note: Use 10% (v/v) as inokulum.
Solution occurs in 14 other media (first defined in Medium 318).
