Inhibition zone formed by P. canescens extract. Penicillium canescens extract (250 μg/ml) was tested for the antibacterial potential against the test bacteria seeded onto Mueller-Hinton agar (MH) by the disc diffusion assay. The plates were incubated for 24 h at 35+ °C and the presence of or absence of the inhibitory zone around the disc was measured and represented.
