  • Ordered UV cuvettes
  • Began growing up 6 3ml cultures of crp* in LB
  • Will TELT dna prep them tonight or tomorrow

M9 Minimal Media (250mL each):

For ~250mL of media and a final 0.2% sugar concentration:

  • 200mL sterile water
  • 50mL of 5X M9 salts
    1. 12.8g Na2HP04*7H2O
    2. 3g KH2PO4
    3. 0.5g NaCl
    4. 1g NH4Cl
    5. Dissolve in 200mL deionized water and autoclave to sterilize
  • 3.75g BactoAgar

Autoclave to sterilize and allow to cool until you can hold it for 2 seconds on the palm of your hand. Then add the following and pour into plates:

  • 25mL sugar solution
    1. Add 0.5g glucose/xylose to 25mL sterile water
    2. Filter-sterilize before adding
    3. Makes a 12.5% sugar solution and a 0.2% overall glucose/xylose media
  • 500 uL 1M MgSO4
    1. Dissolve 24.65g MgSO4*7H20 in 100mL H20
    2. Autoclave to sterilize
  • 25uL 1M CaCl2
    1. Dissolve 14.7 g CaCl2*2H2O in 100mL H2O
    2. Autoclave to sterilize

I will make 250mL of each of the following:

  • 0.2% glucose
  • 0.2% glucose + 0.2% xylose
  • 0.2% xylose
  • 0.2* glycerol (- control)

Protocol for plates

  • DNA prep on crp* cultures from this morning using TELT method
