DR: Defined minimal media for D. radiodurans

250 ml	500 ml	Component
50 ml	100 ml	5x M9 salts
250 ul	500 ul	5mM MnCl2
250 ul	500 ul	0.8M MgCl2
250 ul	500 ul	0.18 M CaCl2
2.5 ml	5 ml	Syringe filtered Vitamins Mix
500 ul	1 ml	Syringe filtered Amino Acid mix (see below)

Add dH₂O to final volume.
Note: All components are either pre-sterilized or syringe filtered so the only things that need to be autoclaved are the receiving bottle and the added water.

To prepare the amino acids:

Amount	Amino Acid
1 g	L-Cys
0.5 g	L-His
0.5 g	L-Met

Dissolve these amino acids in 40 ml of dH₂O
