Mix components, except L-cysteine·HCl·H2O, and adjust pH to 6.5. Distribute the medium into appropriate culture vessels (e.g., 20 ml of the medium in 120 ml serum bottles) under a N2 atmosphere, seal with butyl rubber stoppers and autoclave. Separately autoclave concentrated (100- or 200-fold) L-cysteine·HCl·H2O solution under a N2 atmosphere. Prior to inoculation, add the sterile L-cysteine·HCl·H2O solution. Pressurize the inoculated vessels to 100 kPa N2.
Comment: For strain JCM 12418, inoculate with a 10% inoculum.
