1 Mix ingredients, except NaHCO3, methanol, cysteine x HCl and Na2S x 9H2O, and bring to a boil for 5-10 sec. Cool down under a stream of N2-CO2 (80:20), and add NaHCO3 and methanol 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 N2-CO2 (80:20) and seal with butyl rubber stoppers. After autoclaving, stand the medium overnight. Separately autoclave cysteine x HCl and Na2S x 9H2O as 5% solutions, respectively, under a N2 atmosphere. Prior to inoculation, aseptically and anaerobically add the cysteine x HCl and Na2S x 9H2O solutions.
