1 Dissolve ingredients (except bicarbonate, acetate, fumarate, vitamins, and sulfide), then sparge medium with 80% N2 and 20% CO2 gas mixture for 30 - 45 min to make it anoxic. Dispense under same gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave. Add acetate, fumarate, vitamins and sulfide from sterile anoxic stock solutions prepared under 100% N2 gas and bicarbonate from a sterile anoxic stock solution prepared under 80% N2 and 20% CO2 gas mixture. Stock solutions of vitamins and fumarate should be sterilized by filtration. Adjust pH of the complete medium to 7.0-7.2, if necessary.
Solution occurs in 23 other media (first defined in Medium 792).
