Growth Media
LB
Media (per liter)
- 10 g Bactotryptone
- 5 g Yeast Extract
- 10 g NaCl
- pH to 7.0 with NaOH/HCl
- Autoclave
Plates
- Add 15 g Bacto-Agar per liter media
- Autoclave for 25 minutes
- If antibiotics necessary, add only once media has cooled to ~45ºC, or is comfortable to the touch
- Pour in sterile environment (~15ml per plate)
- Cool in such a way as to avoid accumulation of condensation, while maintaining sterility
- Seal with parafilm, place in bag, and store at 4ºC
LBM
Media (per liter)
- 10 g Bactotryptone
- 5 g Yeast Extract
- 5 g NaCl
- 0.4066 g MgCl2.6H2O (or 2mL 1M MgCl2)
- pH to 7.0 with NaOH/HCl
- Autoclave
Plates
- Add 15 g Bacto-Agar per liter media
- Autoclave for 25 minutes
- If antibiotics necessary, add only once media has cooled to ~45ºC, or is comfortable to the touch
- Pour in sterile environment (~15ml per plate)
- Cool in such a way as to avoid accumulation of condensation, while maintaining sterility
- Seal with parafilm, place in bag, and store at 4ºC
Top Agar (per liter)
- 500 mL LBM
