1 Mix ingredients, except NaNO3, FeSO4 x 7H2O and Na2S x 9H2O, and autoclave under a N2 atmosphere. Separately autoclave NaNO3, FeSO4 x 7H2O and Na2S x 9H2O solutions (pH 7.0, 7.5 and 7.5, respectively) under a N2 atmosphere. Aseptically and anaerobically add the NaNO3, FeSO4 x 7H2O and Na2S x 9H2O solutions to the medium and adjust pH to 6.0. Pressurize the inoculated bottle to 200 kPa N2.
