Tests of antibiotics' stocks
Six plates of LB agar were made.
Five of them contained one of those antibiotics in the dilution 1:1000:
- Chloramphénicol
- Kanamycin
- Erythromycin
- Ampicilin
- Tetracyclin
(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:
- DH5a tranformed with pCB1C3
- Top10 transformed with pQexp
- DH5a pyr tranformed with pMK2
Bacteria tranformed with plasmid were cultivated with the corresponding antibiotic for the selection.
For each medium we make a negative contrôle without bacteria.
