1 Mix ingredients except Trace vitamins, NaHCO3 and Na2S x 9H2O. Separately autoclave NaHCO3 and Na2S x 9H2O (4 and 5% solutions, respectively) under a N2-CO2 atmosphere. Anaerobically and aseptically add the NaHCO3 and Na2S x 9H2O solutions, and filter-sterilized Trace vitamins to the medium. Check final pH to be 7.0 - 7.2. Pressurize the inoculated bottles to 70 kPa N2-CO2 (4:1, v/v).
