Why might the zone of inhibition not be a perfect circle?
I was wondering if you could explain to me why the zone of inhibition might not appear as a perfect circle on an agar plate.
Certainly! One reason for a non-perfect circle might be due to diffusion of the antibiotic in the agar, causing the concentration gradient to be uneven. Another reason could be irregularities in the surface of the agar plate or uneven distribution of bacteria.
