Soil experiment

by Coralie

Water

Sea Water separate in 5mL in 50mL Falcon Fresh water separate in 5mL in 50mL Falcon Contamination with 1mL Water + LB Water + concentrate cells solution Water + concentrate cells solution 10 fold dilution Water + concentrate cells solution 100 fold dilution

J0: we take 100µL of each water and put it on plates with specific antibiotic:

  • MacConkey + Spectinomycin
  • MacConkey + Tetracyclin
  • MacConkey + Chloramphenicol

And only MacConkey for the Water + LB

Incubation ON, 37°C

Soil

Observation of plates (03/08/2015):

Less contamination on plates with MCK+Sorbitol thant MCK+Lactose.

We choose to only use MCK+Sorbitol now

Low Budget Challenge

by Coralie

Observation of plates (03/08/2015): We can saw a little bit of colony. We can suppose that the initial culture wasn't enough in growing phase.

We try another time, with the same protocol than the 03/08/2015 but a fresh culture of bacteria.
