1 Dissolve sodium chloride, potassium hydrogenphosphate and ammonium chloride, then sparge solution with 80% N2 and 20% CO2 gas mixture for at least 30 - 45 min to remove dissolved oxygen and to saturate the solution with CO2. Dispense solution under air atmosphere in Erlenmeyer flasks to 10% of volume, close with screw caps and autoclave. Add trace elements, calcium chloride, magnesium chloride, thiosulfate, bicarbonate and vitamins from sterile stock solutions and adjust pH of the medium to 7.0 - 7.2, if necessary. Incubate with shaking.
2 Note: Use at least 10% (v/v) as inoculum.
