Schematic presentation of the contact bioautographic method: (a) microbes are inoculated on an agar plate; (b) a developed chromatographic plate is flipped over an agar plate to create a chromatographic image and transfer the active compounds, and inoculated plates are incubated for 48 h at 37 °C, and finally, (c) the zones of inhibition can be seen on the agar around the active antimicrobial compounds (adapted from [28,127,128,131]).
