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 serum vials to 10% of volume, seal with butyl rubber stoppers and autoclave. Add trace elements, calcium chloride, magnesium sulfate, thiosulfate, and vitamins from sterile stock solutions prepared under 100% N2 gas and bicarbonate from a sterile anoxic stock solution prepared under 80% N2 and 20% CO2. Thiosulfate and vitamins are sterilized by filtration. Adjust pH of the medium to 7.5 using a sterile stock solution of sodium carbonate (5% w/v). Incubate with shaking. | |||||
2 Note: Use at least 10% (v/v) as inoculum. |
