Abstract
A lichen-forming fungus was successfully isolated by discharged spore method from Korean lichen (Hetero-dermia sp.) and cultivated in pure culture. The isolate JR0012 inhibited mycelial growth of several plant-pathogenic fungi. Mycelial growth of the four Pythium spp. tested was completely inhibited. Potato dextrose broth was found to be the medium favorable for large-scale production of antibiotics from the isolate. Anti-fungal substances produced in axenic culture were partially purified. This is the first report in Korea of lichen-forming fungus successfully isolated and which exhibited strong antifungal activity against plant-pathogenic fungi, especially the four Pythium spp..
