1 Sparge solution A with 80% H2 and 20% CO2 gas for 30 – 45 min to make it anoxic, distribute under same gas atmosphere into anoxic Hungate-type tubes or serum vials to 30% of their volume and autoclave. Solution B is autoclaved separately under 80% N2 and 20% CO2 gas atmosphere. Solutions C and D are prepared under 100% N2 gas and sterilized by filtration. Solution E is autoclaved under 100% N2 gas. To complete the medium appropriate amounts of solutions B to E are added to the sterile solution A in the sequence as indicated. Adjust pH of complete medium to 6.0 - 6.5, if necessary.
