| - | <h4> <u>Tests of antibiotics' stocks</u> </h4>
| |
| - |
| |
| - | Six plates of LB agar were made.
| |
| - | Five of them contained one of those antibiotics in the dilution 1:1000:
| |
| - | <ul>
| |
| - | <li> Chloramphénicol
| |
| - | <li> Kanamycin
| |
| - | <li> Erythromycin
| |
| - | <li> Ampicilin
| |
| - | <li> Tetracyclin
| |
| - | </ul>
| |
| - | (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.
| |
| - |
| |
| - | <h4> <u>Survivability tests</u> </h4>
| |
| - | 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.
| |
| - |
| |
| - | <h4> <u>Pre-cultures</u> </h4>
| |
| - | 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.
| |
| - | <u>From glycerol stocks:</u>
| |
| - | <ul>
| |
| - | <li>Bl21
| |
| - | <li>Top10
| |
| - | <li>DH5a
| |
| - | </ul>
| |
| - | <u>From plates:</u>
| |
| - | <ul>
| |
| - | <li>DH5a tranformed with pCB1C3
| |
| - | <li>Top10 transformed with pQexp
| |
| - | <li>DH5a pyr tranformed with pMK2
| |
| - | </ul>
| |
| - | Bacteria tranformed with plasmid were cultivated with the corresponding antibiotic for the selection.
| |
| - | For each medium we make a negative contrôle without bacteria.

| |
| - | 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

| |
| - | The initial OD at 600nm of each bacteria has been mesured to after be able to calculate the ΔOD at 600nm, during three days.
