Preparation
- Mix components thoroughly, adjust pH to 6.0 with 1 N HCl and autoclave under a H2-CO2 (4:1, v/v) gas mixture. After cooling, aseptically and anaerobically add the following solutions (autoclaved or *filter-sterilized):
- Readjust pH to 6.0 to 6.3, if necessary.
- Mix 2.4 g iron(III) citrate and 90 ml distilled water, and boil until dissolved. Cool to an ambient temperature and adjust pH to 6.0 with 10 N NaOH solution. Fill up to 100 ml with distilled water.
