| 1 Dissolve ingredients (ecxept carbonate, hydrogencarbonate, sulfur, yeast extract and acetate), then sparge medium with 100% N2 gas for 30 - 45 min to make it anoxic. Add solid carbonate and bicarbonate, adjust pH to 9.0 - 9.2, and dispense under 100% N2 gas atmosphere into anoxic Hungate-type tubes or serum vials containing already the appropriate amount of sulfur. Sterilize medium by autoclaving at 110°C for 20 min. Add yeast extract and acetate from sterile anoxic stock solutions prepared under 100% N2 gas. | |||||
