Plasmid pIJ773

With the Macherey-Nagel Extraction kit

Soil experiment

by Coralie

Soil

Observation of plates (31/07/2015):

  • Soil + H2O on new MCK: lots of colonies are visible
  • Soil + LB on new MCK: lots of colonies are visible
  • LB on new MCK: nothing
  • MCK alone: nothing

We can suppose two different hypothesis:

  • The soil is contaminated
  • the MCK isn't OK for our experiment: now we add lactose in the preparation. We will try with sorbitol instead of lactose.

We try soil + H2O and soil +LB on:

  • MCK + Sorbitol: Without antibiotics, with Spectinomycine, Tetramycine or Chloramphenicol
  • MCK + Lactose: Without antibiotics, with Spectinomycine, Tetramycine or Chloramphenicol

Incubation ON, 37°C
