Concentrations ranging from 5 to 800 μg/mL for antibacterial activity tests, and 50 to 2000 μg/mL for antifungal activity tests were employed by diluting the stock solution in appropriate volumes of water. Serial nutrient agar plates were then prepared by pouring of molten media into sterile Petri dishes and incubated at 37 °C for 24 h to check for any sort of contamination. The inoculums were then swabbed uniformly and allowed to dry for 5 min.
