The plates obtained from the speading of yesterday can't be used because there are not single colonies.
We have to try again, but with a stronger dilution of the bacteria or with a smaller volume of spreading.

  • Resuspension of some bacteria from the glycerol stock into 1 mL of LB+antibiotic
  • Dilution 10 and dilution 100.
  • Spreading of each dilution on a LB plate containing the right antibiotic
  • Overnight incubation
