Experiment and Results

1. Inoculate recombinant strains into 20ml LB.Cultivate at 37°C overnight.

2. Add 200ul indicator inoculum (Micrococcus Lysodeikticus or Escherichia Coli) untill heated LB solid medium (100ml) cool to about 50°C.

3. Use puncher make several hole on the LB plate.Add 80ul recombinant strains inoculum into the hole.Cultivate at 37°C overnight.

4. Observe whether LB plate will appear inhibition zone. .
