1 Prepare all solutions and autoclave under a N2 atmosphere. After cooling, combine the solutions and replace the gas phase with a N2-CO2 (4:1, v/v) gas mixture. Then, aseptically and anaerobically add the following autoclaved or *filter-sterilized solutions to the medium:
Sodium acetate
(1.0 M)
10.00 ml - -
Vitamin solution
(*)
1.00 ml - -
Thiamine solution
(*)
1.00 ml - -
Vitamin B12 solution 0.05 g/L
(*)
1.00 ml - -
2 Check the final pH of the medium to be around 7.3.
3 Comment: JCM 14587 grows also in a modified medium with benzene and chlorate. For preparation of the modified medium, replace NaNO3 with 1.06 g NaClO3(in 900 ml solution A). After combining all solutions (A, B and C), add 1.0 ml/L of 1.0 M sodium acetate solution (autoclaved), 25 ml/L of 20 mM benzene (water-saturated, autoclaved), and 1 ml/L of each of vitamin solution (see Medium No. 403, filter-sterilized), thiamine solution (see Medium No. 403, filter-sterilized) and vitamin B12 solution (see Medium No. 403, filter-sterilized) to the medium. Otherwise, prepare the modified medium as described above.
