1 Dissolve ingredients (except cysteine and cellobiose) and sparge medium with 100% N2 gas for 30 - 45 m in to make it anoxic. Add cysteine, adjust pH to 7.2 and dispense under 100% N2 gas atmosphere into anoxic Hungate-type tubes or serum vials and autoclave. After sterilization add cellobiose from an anoxic stock solution sterilized by filtration. | |||||
2 Note: Some strains can be adapted to cellulose as substrate using 5.0 g/l cellulose (Lens tissue, OXOID; or cellulose powder MN 301, MACHEREY-NAGEL). If necessary adjust pH of completed medium to 7.2. |
