Main sol. J1200 #

ml
Equipment needed: Filter Autoclave
Compound Amount Unit Conc. [g/L] Conc. [mM]
MgCl2 x 6 H2O 0.93 g 0.93 4.574
KCl 1.00 g 1 13.414
CaCl2 x 2 H2O 0.12 g 0.12 0.816
NaNO3 0.17 g 0.17 2
Distilled water 992.00 ml - -
1 Mix components and autoclave. For preparation of solid medium, add 15.0 g/L agar before autoclaving. After cooling to 55C, add the following solutions (autoclaved or *filter-sterilized) to the medium:
HEPES buffer
(pH 7.0, 2 M) 		5.00 ml - -
1 M Phosphate buffer
(1 M) 		0.15 ml - -
FeCl2 solution 1.00 ml - -
Trace element solution 1.00 ml - -
Vitamin solution
(*) 		1.00 ml - -
2 Distribute the culture medium into culture tubes (leave > 80% volume of a gas phase)and seal with butyl rubber stoppers. Finally, add methane to make a concentration of 50% in the gas phase (by volume).

1 M Phosphate buffer #
