1 Dissolve ingredients (except carbonate, sucrose, vitamins and reducing agents), then 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 sucrose, 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 mixture. Vitamins are prepared under 100% N2 gas and sterilized by filtration. The pH of the complete medium should be at 7.0.
Solution occurs in 263 other media (first defined in Medium 320).
