October, 5th

pH sensor
  • Infection of 4 ml LB + Amp with 8 ul from glycerol stock of:
    • RBS33
    • A2
    • pNhaA
  • Overnight incubation of the three cultures.

October, 6th

4th experiment

  • We put 50 ul into 5 ml LB NaCl 250 mM + Amp pH 6,6 falcon for each of the overnight cultures RBS33 - A2 - pNhaA and incubated them for four five hours.
  • OD measure of the three falcon with TECAN in order to make dilutions with a final volume of 3 ml and an OD equal to 0,02.
  • We diluted:
    • RBS into:
      • LB NaCl 250 mM + Amp pH 5,5
      • LB NaCl 250 mM + Amp pH 6,6
      • LB NaCl 250 mM + Amp pH 7,5
      • LB NaCl 250 mM + Amp pH 8,5
    • pNhaA into:
      • LB NaCl 250 mM + Amp pH 5,5
      • LB NaCl 250 mM + Amp pH 6,6
      • LB NaCl 250 mM + Amp pH 7,5
      • LB NaCl 250 mM + Amp pH 8,5
    • A2 into:
      • LB NaCl 250 mM + Amp pH 5,5
      • LB NaCl 250 mM + Amp pH 6,6
      • LB NaCl 250 mM + Amp pH 7,5
      • LB NaCl 250 mM + Amp pH 8,5
  • We started this 24 hours experiment that performed absorbance and fluorescence measures (on three different wells) for each sample every 5 minutes.

5th experiment (with this experiment we try to give E.coli a pH and sodium shock in order to see if something happens).

  • We put 50 ul into 5 ml LB NaCl 70 mM + Amp pH 6,6 falcon for each of the overnight cultures RBS33 - A2 - pNhaA and incubated them for four four hours and a half.
  • OD measure of the three falcon with TECAN in order to make dilutions with a final volume of 3 ml and an OD equal to 0,02.
  • We diluted:
    • RBS into:
      • LB NaCl 600 mM + Amp pH 10
      • LB NaCl 600 mM + Amp pH 11,2
    • pNhaA into:
      • LB NaCl 600 mM + Amp pH 10
      • LB NaCl 600 mM + Amp pH 11,2
    • A2 into:
      • LB NaCl 600 mM + Amp pH 10
      • LB NaCl 600 mM + Amp pH 11,2
  • We started this 6 hours experiment that performed absorbance and fluorescence measures (on three different wells) for each sample every 5 minutes.
