| 1 Dissolve ingredients except cysteine and cellobiose. Sparge medium with 100% N2 gas for 30 - 45 min to make it anoxic, then add cysteine and adjust pH to 7.2. Distribute medium under same gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave. Add cellobiose after autoclaving from an anoxic stock solution prepared under 100% N2 gas atmosphere and sterilized by filtration. Adjust pH of the complete medium to 7.2, if necessary. | |||||
