1 Dissolve ingredients except cysteine, maltose and vitamins. Sparge medium with 100% N2 gas for 30 - 45 min to make it anoxic, then add and dissolve cysteine and adjust pH to 7.5 with NaOH. Dispense medium under 100% N2 gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave. Add glucose and vitamins after autoclaving from anoxic stock solutions prepared under 100% N2 gas and sterilized by filtration. |
