Unless otherwise stated, sterilize media by autoclaving at 121°C for 15 min.


Salt base solution (see below)  1.0     L
Trace minerals (see below)  10.0     ml
Citric acid  5.0     mg
Yeast extract (BD-Difco)  1.0     g
Bacto peptone (BD-Difco)  5.0     g
Sulfur (powder)  30.0     g
Na2S·9H2O  0.5     g

Mix ingredients, except sulfur and Na2S·9H2O, and adjust pH to 6.5 with H2SO4. Sterilize by filtration under a N2 atmosphere. Steam sulfur for 3 hr on each of 3 successive days. Neutralize Na2S·9H2O as a 5% solution, and autoclave under a N2 atmosphere. Aseptically and anaerobically add sterile sulfur to the medium. Prior to inoculation, add the sterile Na2S·9H2O solution, and readjust pH to 6.5, if necessary.
