The effects of the lichenicolous fungus on the antimicrobial potential of the lichen demonstrated that the extracts investigated have antimicrobial potential against gram-positive and negative bacteria, and yeast, and inhibit the germination of fungal spores. Inhibition activity varied considerably depending on the extract, the bacterial species, and the absence or presence of ; unparasitised has a higher antimicrobial activity. Methanol and acetone extracts of alone have higher inhibition diameters than with against ; the methanol extract of showed the best inhibition (250 µg/ml). also has a high lysozyme potential against and . Fungal hyphae of were more affected by the methanol extract from .
