Miniprep and sequencing
Miniprep of:
- pVeg-YFP TetR in pHM3 -> Sequence ok
- TetO pVeg-YFP TetR in pHM3 -> Sequence shows that only TetO was there
- YFP TetR BB -> SpeI site are not there in the 2 clones sequenced
- ComS -> Ok on the two clones sequenced

Preparation of slides
Dilution of overnight cultures : PY79 (gfp-) and PY79 (gfp+) .
We waited to an OD of 0.4 (600 nm).
Two well slides : 1-control (PY79 only) 2-Mix (both strains)
Observation
-37°C Microscopy-
We observed the plate with TRANS and YFP-filter settings on the Nikon microscope. We quickly saw that our PY79 + S12 gene was not correct since we found only one cell producing GFP. We will retry the experiment tomorrow with the other -20°C glycerol for this strain, hoping it is not contaminated.
We followed the plate a few hours nonetheless but no result was visible (the fluorescent cell divided only 2 times).
