NB: The negative control with E.Coli does'nt work on any plates. The culture was probably too old.
A problem occurs with stocks of electro-competent Pseudovibrio because wa can see that it growth on Kanamycine 1:1000. On Chloramphenicol, the contamination does'nt seem to grow.
We have to prove that it's Pseudovibrio wich growth on Chloramphenicol. Sep 02

Amplification of pRhokHI-2 in E.Coli Bl21 - Results
After incubation overnight we can see some colonies of E.Coli Bl21 transformed on LB+Cam 1:1000 and on LB+Kan 1:1000. Our Bl21 which had not been transformed doesn't growth on these media but both grow on LB only.
We had well success to tranform E.Coli and amplifly the plasmid.
![Transfo2](https://static.igem.org/mediawiki/2014/0/09/Pouet.jpg)
We tranfered two colonies into liquid MB+Kan(1:1000) and let them in incubator overnight to have a pre-culture for the plasmid purification with NucleoSpin Plamsid Kit (Macherey Nagel).

Amplification of pRhokHI-2 in E.Coli Bl21
The transformation of E.Coli with pRhokHi-2 still didn't works. We still have to amplify it so we re-tried to the tranformation (1µL of plasmid for 40µL of cells, 1800V).
This time, after a liquid culture of only one hours cells were plated on LB 1X + Kan (1:1000), LB 1X + Cam (1:1000), and LB only and let in incubator overnight.

Transformation of Pseudovribrio with pBBR1MCS - Results
We saw no colony on our plates. We decided to test our two replicates of transformation on MB 1X plates with other concentrations of antibiotic. We made three plates with Cam 1:5000, and 1:10 000, then Pseudovibrio were showed on them and let overnight in incubator.

Transformation of Pseudovribrio with pBBR1MCS
After made a purification of pBBR1MCS with NucleoSpin Plamsid Kit (Macherey Nagel), electrocompetent Pseudovibrio cells were tranformed with the plasmid by electroporation (1µL of plasmid for 40µL of cells, 1800V), then they were incubated for three hours and showed on MB 1X+Cam (1:1000) plates. Plates are let in incubator overnight.

Unfortunately the transformation with pRhokHI-2 didn't works so we have to retry.

New stocks are ready for antibiotics' tests on Pseudovribrio
Launch of antibiotics's tests in liquid M9 1X
For each tested antibiotic we made the following range of concentrations:
0 | 1:500 | 1:1000 | 1:50 000 | 1:100 000 |
We made these range two time to have a replicate and we added a controle tube without antibiotic for each bacteria.
Each tube is made like in the following table in Falcon tubes (15mL):
/ | 0 | 1:500 | 1:1000 | 1:50 000 | 1:100 000 |
Medium+agar | 3mL | 3mL | 3mL | 3mL | 3mL |
Antibiotic | 0 | 6µL of stock | 3µL of stock | 6µL of stock diluted 1/100 | 3µL of stock diluted 1/100 |
Pre-culture | 300µL | 300µL | 300µL | 300µL | 300µL |
For each range, we test Pseudovibrio denitrificans but also E.Coli and E.Coli tranformed with a speicific resistance cassette (NM:The E.Coli strain for the control case is the same strain that is tranformed for the cassette efficiency test).
The initial OD at 600nm of each bacteria has been mesured to after be able to calculate the ΔOD at 600nm, during three days.
/ | Pseudo | Bl21 | DH5a | Top 10 | DH5a pyr+KanR | DH5a+CamR | Top 10+ErmR |
OD init | 0.02 | 0.795 | 0.873 | 0.693 | 0.408 | 0.687 | 0.319 |
Plates for antibiotics's tests
For each tested antibiotic we made the same range of concentrations than in liquid.
We also made these range two time to have a replicate and we added a controle plate without antibiotic on which we showed all our tested bacteria. Plates will be checked during three days.
We made these same ranges of tested antibiotic's concentrations for three media:
- MB agar 1X
- MB agar 0.5X
- M9 agar 1X
Each plate is made like in the following table:
/ | 0 | 1:500 | 1:1000 | 1:50 000 | 1:100 000 |
Medium+agar | 20mL | 20mL | 20mL | 20mL | 20mL |

Plates | LB Agar only | LB+Cam | LB+Kan | LB+Amp | LB+Erm | LB+Tet |
E.coli | X | 0 | X | 0 | X | 0 |
There was a problem with the stock of Kanamycine so we made a new one at 25mg/mL.
For the erythrompycine, we learn that E. Coli is not really sensitive to this antibiotic and that it's better to use it with a dilution at 1:100.
Survivability tests - Results
liquid cultures/Plates | MB | M9 |

Any liquid culture can be plated and will grow up. Of course, it works better on MB medium, wich is a rich medium than on M9.

Tests of antibiotics' stocks
Six plates of LB agar were made.
Five of them contained one of those antibiotics in the dilution 1:1000:
(The last one was the control of the growth of our bacteria without antibiotics) We sowed 10µL of a liquid LB culture of Bl21, and we let them incubate overnight at 37°C.
Survivability tests
Two plates of MB 1X and M9 1X were made and divised in two parts. Each plate was sowed with 5µL of a liquid MB 1X culture of Pseudovibrio denitrificans(dated 12th August) in a part and with 5µL of a liquid M9 1X culture Pseudovibrio denitrificans (dated 12th August) in the other part.
Pre-cultures
Cultures in MB 1X and M9 1X of Pseudovibrio were passed by a 1/10 dilution and let incubate overnight at 30°C. New cultures of different E.Coli were also started from glycerol or plate and let incubated overnight at 37°C.
From glycerol stocks:
From plates:
Bacteria tranformed with plasmid were cultivated with the corresponding antibiotic for the selection. For each medium we make a negative contrôle without bacteria. Aug 16
