Culture Medium and Culture Conditions

Media

LB Medium

  1. weight components
    5 g/L NaCl
    10 g/L tryptone
    5 g/L yeast extract
    (15 g/L agar for plates)
  2. fill up to 1 L with deionized water
  3. mix well by shaking
  4. autoclave
    1. autoclaving tape, caps slightly unscrewed
    2. base of the pot has to be covered with deionized water
    3. close lid
    4. heat level 3 until the pressure valve opens
    5. reduce heat level to 1.5
    6. set timer to 20 minutes
    7. turn heater off
    8. wait until the pressure valve retracts (30-45 minutes)
    9. open, close caps & shake
  5. for plates, wait until you can touch the bottle (<60 °C, clean bench!)
  6. add antibiotics (1 µL/mL) and shake (gloves!)


TB Medium

  1. components 1:
    4 mL/L glycerol
    12 g/L tryptone
    24 g/L yeast extract
  2. fill up to 900 mL with deionized water
  3. mix well by shaking
  4. autoclave
  5. components 2:
    0.17 M KH2PO4
    0.72 M K2HPO4
  6. dissolve in 100 mL deionized water and sterilize it by passing it through a filter
  7. after autoclaving and cooling down, add sterile phosphate solutions
