A bacterial culture (200 μL containing 1.8 × 109 cells) was treated with an antibiotic Z (50 μg per mL) for 4 h at 37°C. After this treatment, the culture was divided into two equal aliquots.
Set A: 100 μL was plated on Luria agar.
Set B: 100 μL was centrifuged, the cell pellet washed and plated on Luria agar.
After incubating these two plates for 24 h at 37°C, Set A plate showed no colonies, whereas the Set B plate showed 0.9 × 109 cells. This experiment showed that the antibiotic Z is
Thin layer of material B (of total amount m) is plated on the end faces of two long rods of material A. These are then joined together on the plated side (see the figure below) and heated to a high temperature. Assuming the diffusion coefficient of B in A is D, the composition profile CB along the rod axis x after a time t is described by
