Mix ingredients, except yeast extract and Na2S·9H2O, adjust pH to 6.5 with H2SO4, and filter-sterilize under a N2 atmosphere. Separately autoclave 10% yeast extract solution and neutralized 5% Na2S·9H2O solution under a N2 atmosphere. Aseptically and anaerobically add the yeast extract solution to the medium. Prior to inoculation, add the Na2S·9H2O solution to the medium, and readjust pH to 6.5 - 7.0, if necessary. Cultivate under a N2 atmosphere.
