Mix ingredients, except L-sodium lactate, NaHCO3 and Na2S·9H2O, and autoclave under a N2-CO2 (4:1, v/v) atmosphere. Separately, autoclave L-sodium lactate in 10 ml distilled water anaerobically and filter-sterilize 5% NaHCO3 gassed with N2-CO2 (4:1, v/v) for 20 min. Add the sterile L-sodium lactate and NaHCO3 solutions to the medium. Prior to inoculation, add an anaerobically autoclaved 5% Na2S·9H2O solution to the medium.
