<!--  <u>3 solutions: </u><br />
+
<br />
+
  <u>Solution 1: (salts)</u><br />
+
  5.3 g of Potassium  Phosphate (dibasic) K<sub>2</sub>HPO<sub>4</sub><br />
+
  2 g of Potassium  Phosphate (monobasic) KH<sub>2</sub>PO<sub>4</sub><br />
+
  1 g of Ammonium  Sulfate (NH<sub>4</sub>)<sub>2</sub>SO<sub>4</sub>.<br />
+
  0.5 g of Sodium Citrate (tribasic, dihydrate) <br />
+
  Autoclave<br />
+
  Complete with  water to 333 ml</p>
+
<p style="text-align:left"><u>Solution 2: (agar)</u><br />
+
  16 g of agar<br />
+
  Complete with  water to 333 ml<br />
+
  Autoclave</p>
+
<p style="text-align:left"><u>Solution 3: (sugar)</u><br />
+
  In fact we have  to put 4 g of sugar in 333 ml of H<sub>2</sub>O. We wanted to see if <i>E. coli</i> bacteria took TPA  as a carbon source. So just the water was added. Next, the flask was autoclaved.</p>
+
<p>&nbsp;</p>
+
<p style="text-align:left">When the three  parts have been autoclaved, 2 more ingredients must be added to the medium aseptically:<br />
+
  1 ml of 10%  magnesium sulfate MgSO<sub>4</sub> (autoclaved too) (1.5 g in 15 ml of H<sub>2</sub>O).<br />
+
  1 ml of 0.2%  Thiamin (vitamin B1).</p>
+
<p style="text-align:left">At the end the  volume of Agar was exceeded (350 ml and not 333 ml). So we had to redo this  experiment the next day.</p>

+
<p style="text-align:left"><strong><u>Protocol:</u></strong><strong>&nbsp;</strong>(for 1 l medium)</p>
+
<p style="text-align:left">Agar was directly  put in a bottle and salts were dissolved in a beaker with water.</p>
+
<p style="text-align:left">6 g of Sodium  Phosphate Na<sub>2</sub>HPO<sub>4</sub>.H<sub>2</sub>O<br />
+
  3 g of Potassium  Phosphate KH<sub>2</sub>PO<sub>4</sub><br />

+
  1 g of Ammonium  chloride NH<sub>4</sub>Cl<br />
+
  16 g of agar<br />
+
  Complete with water to 1l</p>
+
<p style="text-align:left">When this flask  was autoclaved some ingredients were added in aseptical conditions:</p>
+
<p style="text-align:left">1 ml of 1M  Magnesium sulphate MgSO<sub>4</sub> (6.02 g in 50 ml H<sub>2</sub>O)<br />
+
  1 ml of 0.1 M of  Calcium Chloride CaCl<sub>2</sub> (0.55 g in 50 ml of H<sub>2</sub>O)</p>
+
<p style="text-align:left">A mistake was  done yesterday but this time an other did too: The last ingredients were added  but they were not sterile so the medium failed again.</p>
+

+
<p style="text-align:left"><strong><u>Aim:</u></strong> Have prepared M9  medium and minimal medium for Petri dishes</p>
+
<p style="text-align:left">We restarted the last two protocols but this time we included the agar for the future Petri dishes.<br />
+
  For the future  experiments every medium will have the same concentration of sugar for the  bacteria growth, and the test of the TPA toxicity. We began by a theoretical concentration for our Petri dishes: to see the saturation concentration of TPA we decided to do  dilutions at 1/10 and 1/20. <br />
+
  This time we  decided to make 1.5 l of minimal medium<br />
+
  <strong><u>Protocol:</u></strong><strong><u> </u></strong></p>
+
<p style="text-align:left"><strong><u>Solution 1: (salts)</u></strong><strong><u> </u></strong><br />
+
  8 g of Potassium Phosphate K<sub>2</sub>HPO<sub>4</sub> <br />
+
  3 g of Potassium Phosphate KH<sub>2</sub>PO<sub>4</sub> <br />
+
  1.5 g of Ammonium Sulfate (NH<sub>4</sub>)2SO<sub>4</sub> <br />
+
  0.75 g of Sodium Citrate (tribasic, dihydrate) Na<sub>3</sub>C<sub>6</sub>H<sub>5</sub>O<sub>7</sub>.(H<sub>2</sub>O)  2 <br />

<p style="text-align:left"><strong><u>Solution 3: </u></strong><strong><u> </u></strong><br />
+
  500 ml of H<sub>2</sub>O </p>
+
<p style="text-align:left">We underestimated  the time for agar to solidify, so we had solid agar in the <strong><u>test-tube</u></strong>. Moreover one of the flask was  not sterile so we contaminated our medium. We decided to return at the first  protocol (for 1l). </p>
+
<p style="text-align:left">At the end of  this journey the two media were ready but they did not have the last  ingredients.</p>

Toxicity and solubility of TPA (Terephthalic acid)


  1. Dissolution of TPA in DMSO (dimethyl sulfoxide). The best concentration obtained is 62 mg/l

  2. Dilution of TPA stock in LB Broth => TPA precipitates at a concentration of 3.9 g/l, maximum concentration in LB Broth is 0.9 mg/l

  3. Solubilization of TPA by NaOH

  4. Creation of a stock solution of soluble TPA in water at 0.5 mol/l

  5. Test of the TPA Solubilization in LB Broth

  6. Preparation of different media containing terephthalic acid (TPA) and ethylene glycol (EG):
      Media 1 to 10 are made in solid form:
    1. M9
    2. M9 + TPA (1.2 mM)
    3. M9 + TPA (6.0 mM)
    4. M9 + TPA (12.0 mM)
    5. M9 + sucrose (1.2 mM)
    6. M9 + sucrose (6.0 mM)
    7. M9 + sucrose (12.0 mM)
    8. M9 + sucrose + TPA (6.0 mM)
    9. M9 + sucrose + TPA (1.2 mM)
    10. Media 11 to 15 are made in both solid and liquid form:
    11. LB Broth
    12. LB + TPA (1.2 mM)
    13. LB + TPA (6.0 mM)
    14. LB + TPA (12.0 mM)
    15. LB + TPA (20.0 mM)

  7. Growth curve of BAP 1 (E. coli, kindly provided by Blaine Pfeifer, U. Buffalo)in media 11 to 14 in order to assess TPA toxicity.

  8. Plating of BAP 1 bacteria on all solid media to assess TPA toxicity and the ability of TPA to be used as a carbon source.

Enzymatic Assay of NB-Esterase


  1. XbaI ans PstI enzymatic digestion of the Biobrick BBa_K808030 and pDG011 plasmid.

  2. Gel purification of the digested fragments on 0.8% agarose gel.

  3. Ligation of pDG011 plasmid and BBa_K808030 using T4 DNA ligase.

  4. Gel migration on 0.8% agarose gel.
