Preparing growth medium for transduction screening

If the transduction works (i.e. an homologous recombinaison that should delete DapA by inserting an erythromycin resistant cassette), transducted MG1655 Coli should grow in a medium LB+erythro+ DAP but can't grow in a medium LB+erythro without DAP.

  • Preparation of DAP solution from the powder (50mM). See Protocols
  • Making 10 petri dish (LB+tet+citrate+DAP). See Protocols
  • Making 10 petri dish (LB+erythromycin+citrate+DAP). See Protocols

Acinetobacter and E.Coli on LNMM Nile Red solid culture

Nile Red can be excited by light around 312nm (Spiekermann,1999). After 24h incubation, we observed Acinetobacter and E.Coli on LNMM with and without Nile Red:
