acid to 500.0mL of distilled/deionized water. Adjust pH to 6.5 with
KOH. Add remaining components sequentially. Add distilled/deion-
ized water to 1.0L. Mix thoroughly.
Preparation of Medium: Add ferric citrate to distilled/deionized
water and bring volume to 1.0L. Gently heat and bring to boiling. Con-
tinue boiling until ferric citrate is dissolved. Cool to room temperature.
Adjust to pH 6.6 with 10N NaOH. Add remaining components. Mix
thoroughly. Sparge with 80% N2 + 20% CO2 . Anaerobically distribute
into tubes or flasks. Autoclave for 15 min at 15 psi pressure–121°C. Fi-
nal pH should be 7.0.
