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:
    • Bl21
    • Top10
    • DH5a
    From plates:
    • DH5a tranformed with pCB1C3 (CamR)
    • Top10 transformed with pQexp (ErmR)
    • DH5a pyr tranformed with pMK2 (KanR)

    Bacteria tranformed with plasmid were cultivated with the corresponding antibiotic for the selection. For each medium we make a negative contrôle without bacteria.
