  Mix ingredients except for KP buffer, vitamin solution, Na2CO3, Na2S·9H2O and cysteine-HCl. Dispense the medium into suitable culture vessels under a stream of H2/CO2 (80/20) and seal with butyl rubber stoppers. Separately autoclave KP buffer, Na2S·9H2O (5% solution) and cysteine-HCl (5% solution) under a N2 atmosphere. Sterilize vitamin and 10% Na2CO3 solutions by filtration. Prior to inoculation, aseptically and anaerobically add KP buffer, vitamin, Na2CO3, Na2S·9H2O and cysteine-HCl solutions. Pressurize the inoculated vessels to 150 kPa with H2/CO2.
