From Monday the 10th of October to Sunday the 16th of October 2011

Monday

Strain construction

We're back to the lab for few more experiments, so we're building up again the strain we'll need for these experiments.

Transformations : PHL1414/pIG2, PHL1414/pIG6, PHL1414/pIG16, MC4100/p85, MC4100/pIG2, MC4100/pIG6
Note:There was less than 2µl of p85.
Dickeya strain A350 was transformed by electroporation with pIG6 and pIG2. A 5ml of LB liquid culture of 1 clone of both strain is started.
Do not forget that Dickeya doesn't like the cold, so keep the Petri dishes on the bench.

Tuesday

Strain construction

Transformations results:
MC4100/pIG6 --> 1 clone
MC4100/pIG2 --> 2 clones
MC4100/p85 --> 0 clone
PHL1414/pIG2 --> 0 clone
PHL1414/pIG16 --> 5 clones
A 5ml liquid culture of each clone obtened is started.
Extraction and digestion by E and P.
The gel electrophoresis shows that the clones of MC4100/pIG2, MC4100/pIG6, PHL1414/pI16, PHL1414/pIG6 and A350/pIG2 are ok. There is nothing on the digested A350/pIG6 track.

New test for the transformation of pIG20 (same as pIG2) in PHL1414.

Strain collection

S46 = A350/pIG6
S45 = A350/pIG2
The final concentration of glycerol is 40%. (500µl of culture + 500µl of Y80%)

Wednesday

Strain construction

Transformations results: PHL1414/pIG20 --> 3 clones
A 5ml liquid culture is started for two of them.
