Preparation of Trace Elements Solution: Add nitrilotriacetic
acid to 500.0mL of distilled/deionized water. Dissolve by adjusting pH
to 6.5 with KOH. Add remaining components. Add distilled/deionized
water to 1.0L. Mix thoroughly.
Preparation of Medium: Add components to distilled/deionized
water and bring volume to 1.0L. Mix thoroughly. Adjust pH to 7.0 with
Na 2 SO 4 . Autoclave for 15 min at 15 psi pressure–121°C. Distribute
10mL medium into 28mL serum bottles and seal with a rubber stopper.
Gas with atmosphere of 94% N 2  + 3% H 2 + 3% O 2 at 300kPa.
Use: For the cultivation and maintenance of Thermocrinis ruber.
