Mix ingredients, except NaHCO3, cysteine·HCl and Na2S·9H2O, and adjust pH to 6.0. Bring to a boil for 5-10 sec, then, cool down under a stream of H2-CO2 (80:20) and add NaHCO3 to the medium. Dispense the medium into suitable culture vessels (e.g., 20 ml of the medium in 120 ml serum bottles) under a stream of H2-CO2 (80:20) and seal with butyl rubber stoppers. After autoclaving, stand the medium overnight. Separately autoclave cysteine·HCl and Na2S·9H2O as 5% solutions, respectively, under a N2 atmosphere. Prior to inoculation, aseptically and anaerobically add the cysteine·HCl and Na2S·9H2O solutions. Pressurize the inoculated bottles to 200 kPa H2-CO2 (80:20).
