Solid Media Protocol
Solution A
Sterile filter solution with:
- 2 g of Na2S2O3
- 10 mL of H2O
Solution B
Autoclave solution of (2.5% tryptone):
- 2.5g tryptone broth
- 100 mL of H2O
Solution C
Sterile filter solution of:
- 500 mL deionized water
- 27 g (NH4)2SO4
- 0.9 g KCl
- 1.605 g leucine
- 4.5 g MgSO4
- 0.02 g HK2PO4
- 0.485 g diaminopimelic acid
- ~0.7 mL H2SO4 (or enough to bring pH down to ~2.0)
- 20 g Fe(II)SO4 (after adding everything else above)
Solution D
Autoclave solution containing (4% agarose):
- 20 g Agarose
- 500 mL distilled water
- Heat up agarose solution until it becomes liquid
- Pick a volume of solid media to make
- Mix 1% vol A & 50% vol D, and 1% vol B & 48% vol C
- Mix together AD and BC
- Pour into petri dishes and allow to harden
