<li>Transformation Buffer: sterile 10 mM Tris-HCl, pH 7.0, 50 mM CaCl2</li>
 +
<li>Grow a 50 mL culture in LB at 37 deg C from 1 colony.</li>
 +
<li>When OD ~ 0.5, collect the cells in a sterile Falcon tube and chill on ice for 10min.</li>
 +
<li>Centrifuge at 5000 rpm for 10 min at 4 deg C. Discard supernatant.</li>
 +
<li>Resuspend cells in 15 mL of transformation buffer.</li>

 +
</ul>
 +
<br/>
 +
The cells are now ready to be transformed. They can be stored in this state at 4 deg C for under a week.<br/>
 +
Alternatively, the competent cells can be aliquoted (200&micro;L), adding glycerol to a final conc of 15% (v/v), and the cells stored at –80 deg C.<br/>
 +
Every time you make new competent cells you should check for possible contaminations. Plate an aliquot of the new cells in LB plates + antibiotic (i.e. ampicillin, chloramphenicol, kanamycin). Strains such as DH5a, NEB10b, Novablue, should not grow in the presence of antibiotics.<br/>

 +
<b>Competent cells must always stay in ice</b>
 +
<ul>
 +
<li>Thaw home made CaCl2 competent cells on ice.</li>
 +
<li>Add 1&micro;L of DNA to 200&micro;L of competent cells (concentration of DNA stock should be between 50–150 ng/&micro;L).</li>
 +
<li>Incubate on ice for 30 min.</li>
 +
<li>Heat shock at 42&deg;C for exactly 2 min.</li>
 +
<li>Incubate on ice 1 min.</li>
 +
<li>Add 500-700&micro;L of LB (or SOC) and shake at 37&deg;C for 1 h.</li>
 +
<li>Plate the cells (use plates with the appropriate antibiotic according to your plasmid).</li>
 +
</ul>
 +
<br/>
 +
You can either plate a small amount (200&micro;L) of the cells or more.<br/>
 +
You should try a few conditions the first time and then choose the one that gives 30–300 separate colonies.<br/>
 +
If few cells are expected: spin down the cells at 2500 rpm, discard supernatant and resuspend in 150–200&micro;L of LB and plate all the cells.<br/>
 +
<br/>
 +
Plates must be labeled as follow:<br/>
 +
strain – [resistance] – part – “(plasmid)” – YOUR_NAME – date<br/>
 +
<br/>
 +
For ligation you should increase the amount of DNA to be transformed (see cloning protocol).<br/>
 +
<ul><li>Incubate the plates O/N upside down at 37&deg;C.</li></ul>

To test if our system was able to accelerate or to slow down fruit ripening, we designed an ermetically closed jam jar with a rubber hose connector. These jars contained our test-fruit and each one was connected to a flask. The flasks contained 300 ml of induced (or not) culture when its O.D.600 reached 0.8. The flasks contained also a stirrer. The cultures were maintained at 37 &deg;C using a laboratory heating plate connected to a digital thermometer immersed in the culture.<br/>

The program set on the PCR is the following:
+
For some days, every morning the culture in the flasks was substituted with a new induced (or not) colture .<br/>
-

Furthermore, canonical jam jars (i.e.: with no connector) were adopted to contain the negative control fruit samples. All the apparatus was put under the chemical hood. <br/>

To test if our system was able to accelerate or to slow down fruit ripening, we designed an ermetically closed jam jar with a rubber hose connector. These jars contained our test-fruit and each one was connected to a flask. The flasks contained 300 ml of induced (or not) culture when its O.D.600 reached 0.8. The flasks contained also a stirrer. The cultures were maintained at 37 &deg;C using a laboratory heating plate connected to a digital thermometer immersed in the culture.<br/>
+
-
For some days, every morning the culture in the flasks was substituted with a new induced (or not) colture .<br/>
+
-
Furthermore, canonical jam jars (i.e.: with no connector) were adopted to contain the negative control fruit samples. All the apparatus was put under the chemical hood. <br/>

All the measurement have to start by inocula in the correct antibiotics (CM) of MeSA producing cells and of normal Neb10&beta; in LB without antibiotic as control. The inocula need to be growth O/N at 37&deg;C in agitation.

 +
<p>

Then the cells were induced by adding Arabinose 5mM by a solution 1 M prepared by dissolving 0,150 g in 1 mL of dH2O. After two hours in some of the samples was added Salicylic Acid 2mM by a solution 1 M obtained by dissolving 0,138 g in 1 mL ethanol 70%. Then the culture were put for other 2 hours at 37&deg;C in agitation waiting for the 4 hours of induction to pass.

</p>
 +
<p>
 +
The tests could also been in M9 medium because it smells less than LB. To do this, when cells in LB reached an O.D. of 400 they were centrifuged at 4100 rpm for 10 minutes to form a pellet. The supernatant was discarded and they were resuspended in fresh M9 medium with the correct antibiotic. This was done because E.coli cells growth in M9 in much more time than in LB. The cells were therefore induced with Arabinose and after two hours SA was added where needed.

At this point the samples were ready for different test.

Cells

Competent cells preparation
  • Transformation Buffer: sterile 10 mM Tris-HCl, pH 7.0, 50 mM CaCl2
  • Grow a 50 mL culture in LB at 37 deg C from 1 colony.
  • When OD ~ 0.5, collect the cells in a sterile Falcon tube and chill on ice for 10min.
  • Centrifuge at 5000 rpm for 10 min at 4 deg C. Discard supernatant.
  • Resuspend cells in 15 mL of transformation buffer.
  • Chill on ice for 15 min. Spin at 5000 rpm for 10 min at 4 deg C. Discard supernatant.
  • Resuspend cells in 4 mL of transformation buffer.

The cells are now ready to be transformed. They can be stored in this state at 4 deg C for under a week.
Alternatively, the competent cells can be aliquoted (200µL), adding glycerol to a final conc of 15% (v/v), and the cells stored at –80 deg C.
Every time you make new competent cells you should check for possible contaminations. Plate an aliquot of the new cells in LB plates + antibiotic (i.e. ampicillin, chloramphenicol, kanamycin). Strains such as DH5a, NEB10b, Novablue, should not grow in the presence of antibiotics.

Competent cells transformation
Competent cells must always stay in ice
  • Thaw home made CaCl2 competent cells on ice.
  • Add 1µL of DNA to 200µL of competent cells (concentration of DNA stock should be between 50–150 ng/µL).
  • Incubate on ice for 30 min.
  • Heat shock at 42°C for exactly 2 min.
  • Incubate on ice 1 min.
  • Add 500-700µL of LB (or SOC) and shake at 37°C for 1 h.
  • Plate the cells (use plates with the appropriate antibiotic according to your plasmid).

You can either plate a small amount (200µL) of the cells or more.
You should try a few conditions the first time and then choose the one that gives 30–300 separate colonies.
If few cells are expected: spin down the cells at 2500 rpm, discard supernatant and resuspend in 150–200µL of LB and plate all the cells.

Plates must be labeled as follow:
strain – [resistance] – part – “(plasmid)” – YOUR_NAME – date

For ligation you should increase the amount of DNA to be transformed (see cloning protocol).
  • Incubate the plates O/N upside down at 37°C.
!!!Don't plate before four o'clock!!!

pSB1C3 linearization by PCR
This protocol is a Phusion PCR using Suffix Forward and Prefix Reverse primers: in this way it is possible to linearize pSB1C3 removing any insert (like RFP,...). Note: it is advisable to perform the PCR at least in triplicates.

PCR mix
Template 50ng (at least 0.50µl)
HF Buffer 10µl
dNTPs 1µl
Primer Fw (suff) 2.5µl
Primer Rv (pref) 2.5µl
Phusion 0.5µl
Water up to 50µl

Given that pSB1C3 is 2070bp long and that the annealing temperature of the primers used is 58°C, the PCR program to be used is the following:
Step Temperature Time Type Go to
1 98°C 30sec    
2 98°C 10sec Denaturation  
3 58°C 20sec Annealing  
4 72°C 35sec Extend Go to step #2 for 30 times
5 72°C 10min    
6 4°C &infinit;    
Then run the PCR samples on a 1% agarose gel to verify the success of the reactions (each sample is prepared with 8µl of PCR reaction and 2µl of 6X loading die; 1kb ladder is good).

Ethylene detection through Micro GC

An overnight culture was diluited 1:100 and grown until O.D.600 reached 0.5. After that, the culture was induced with 5 mM arabinose and placed with a stirrer in a sealed vial (V = 15 ml) with a pierceable septum. The sample was kept for about 4 hours at 37 °C in thermoshaker. After that the sample was connected to the Micro Gas Chromatograph Agilent 3000A endowed with two colums: a Mol Sieve 5A Plot and a Plot U column (see the tables for colums and method specifications).

A measure was then taken.
In order to estimate how much gas was taken for each measurement using the settings described above, a mass flow meter was connected to the micro GC. During a measurment, a flow of 3 (± 0.15) ml / min was registered. Due to the fact that a measurment lasts 10 s, the withdrawn volume was 0.5 ml.

Application of B. fruity on fruit
To test if our system was able to accelerate or to slow down fruit ripening, we designed an ermetically closed jam jar with a rubber hose connector. These jars contained our test-fruit and each one was connected to a flask. The flasks contained 300 ml of induced (or not) culture when its O.D.600 reached 0.8. The flasks contained also a stirrer. The cultures were maintained at 37 °C using a laboratory heating plate connected to a digital thermometer immersed in the culture.
For some days, every morning the culture in the flasks was substituted with a new induced (or not) colture .
Furthermore, canonical jam jars (i.e.: with no connector) were adopted to contain the negative control fruit samples. All the apparatus was put under the chemical hood.

The apparatus.

MeSA Detection
Sample preparation

To detect if E. coli actually produced Methyl salicilate (MeSA), we tried both qualitative (SNIFF Test) and quantitative (GC-MS) tests.

All the measurement have to start by inocula in the correct antibiotics (CM) of MeSA producing cells and of normal Neb10β in LB without antibiotic as control. The inocula need to be growth O/N at 37°C in agitation. The following day, dilutions 1:100 were done in falcons with fresh LB and the same antibiotic; the cells were growth at 37°C in agitation until O.D.600≈0.6 was reached.

Then the cells were induced by adding Arabinose 5mM by a solution 1 M prepared by dissolving 0,150 g in 1 mL of dH2O. After two hours in some of the samples was added Salicylic Acid 2mM by a solution 1 M obtained by dissolving 0,138 g in 1 mL ethanol 70%. Then the culture were put for other 2 hours at 37°C in agitation waiting for the 4 hours of induction to pass.

The tests could also been in M9 medium because it smells less than LB. To do this, when cells in LB reached an O.D. of 400 they were centrifuged at 4100 rpm for 10 minutes to form a pellet. The supernatant was discarded and they were resuspended in fresh M9 medium with the correct antibiotic. This was done because E.coli cells growth in M9 in much more time than in LB. The cells were therefore induced with Arabinose and after two hours SA was added where needed.

At this point the samples were ready for different test.
