| | Mix ingredients except for vitamin solution, glucose and Na2S·9H2O, and autoclave under a N2 atmosphere. Concentrated sodium sulfide solution is sterilized separately under a N2 atmosphere in tightly closed vessels. Prior to inoculation, add the filter-sterile vitamin and glucose solutions and Na2S·9H2O. Final pH of the medium is 6.9-7.2. |
