1 Dissolve ingredients (except bicarbonate, calcium chloride and vitamins), boil medium for some minutes to dissolve the anthraquinone, then cool under 80% H2 and 20% CO2 gas atmosphere to room temperature. Add solid bicarbonate and adjust pH to 7.2, dispense medium under same gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave. Add calcium chloride and vitamins from sterile anoxic stock solutions prepared under 100% N2 gas atmosphere. Vitamins are sterilized by filtration. Adjust pH of complete medium to 7.2, if necessary.
