1 Dissolve ingredients except trace elements, vitamins and catalase, adjust pH to 7.2 - 7.4, bring medium to the boil and cool to room temperature under 100% N2 gas atmosphere. Dispense under same gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave. To complete the medium add trace elements, vitamins and catalase from sterile anoxic stock solutions prepared under 100% N2 gas atmosphere. Vitamins and catalase should be sterilized by filtration. After inoculation, inject sterile air into the culture vessel up to about 20% of the total gas volume (i.e., 4 parts N2 and 1 part air).
