1 Mix components thoroughly and adjust pH to 7.0 with NaOH. Distribute the medium into culture vessels (e.g., 10.0 ml in 25 ml serum bottles) under a stream of N2, seal with butyl rubber stoppers and autoclave. After cooling, add 80% headspace volume of filter-sterilized H2 gas into the culture vessels. Aseptically and anaerobically add per liter the following solutions (autoclaved or *filter-sterilized and stored anaerobically):
Solution A

Solution occurs in 5 other media (first defined in Medium J976).
Compound Amount Unit Conc. [g/L] Conc. [mM]
EDTA 3.7 g 3.7 12.661
FeSO4 x 7 H2O 1.1 g 1.1 3.957
MnCl2 x 4 H2O 98.4 mg 0.098 -
ZnSO4 x 7 H2O 28.8 mg 0.029 0.1
CoCl2 x 6 H2O 23.8 mg 0.024 0.183
CuCl2 x 2 H2O 17.2 mg 0.017 0.101
Na2MoO4 x 2 H2O 24.2 mg 0.024 0.1
H3BO3 31.0 mg 0.031 0.501
Distilled water 1000.0 ml - -
1 Adjust pH to 6.0 with KOH.
2 Comment: Consistent growth in serum tubes requires pretreatment of butyl rubber stoppers by boiling in 1% sodium sulfide solution (1 hr) followed by boiling in distilled H2O (1 hr, twice).
