aXa-AgNPs are the AgNPs prepared using Xanthoria parietina and Ff-AgNPs are the AgNPs prepared using Flavopunctelia flaventior, Methicillin-resistant Staphylococcus aureus (MRSA), Vancomycin-resistant Enterococcus (VRE), American Type Culture Collection (ATCC), Multi-Drug Resistant (MDR), Tetracycline 30 µg (TE30), Linezolid 30 µg (LZD30), Gentamicin 10 µg (CN10), Ampicillin 10 µg (Amp10). The mean and standard deviation of triplicate were presented in all results.
