Preparation of Wolfe’s Mineral Solution: Add nitrilotriacetic
acid to approximately 500.0mL of water and adjust to pH 6.5 with
KOH to dissolve the compound. Bring volume to 1.0L with remaining
water and add remaining components one at a time.
Preparation of Medium: Add components, except fructose solu-
tion and NaHCO 3 solution, to distilled/deionized water and bring vol-
ume to 940.0mL. Mix thoroughly. Autoclave for 15 min at 15 psi
pressure–121°C. Aseptically add 50.0mL of sterile fructose solution
and 10.0mL of sterile NaHCO 3 solution. Mix thoroughly. Adjust pH to
7.2. Aseptically distribute into sterile tubes or flasks. Fill containers to
capacity.
Use: For the cultivation of Rhodoferax fermentans and Thiocapsa
halophila.
