Swimming agar assay

We wanted to test different conditions for the swimming agar assay:

- different agar concentrations

- different incubation temperatures

- different inoculation depths

After an incubation overnight, we measured the diameter of the E. coli MG1655 swarms. Surprisingly, we observed two swarm layers: The lower one has a bigger diameter than the upper.
