The North American mushroom competitor, Trichoderma aggressivum f. aggressivum, produces antifungal compounds in mushroom compost that inhibit mycelial growth of the commercial mushroom Agaricus bisporus



The North American mushroom competitor, Trichoderma aggressivum f. aggressivum, produces antifungal compounds in mushroom compost that inhibit mycelial growth of the commercial mushroom Agaricus bisporus



Mycological Research 107(12): 1467-1475



We identified a metabolite produced by T. aggressivum isolates in vitro that inhibited the growth of A. bisporus and other fungi. This antifungal compound, which was not produced by 'non-aggressive' T. harzianum isolates under the prevalent culture conditions, was identified as 3,4-dihydro-8-hydroxy-3-methylisocoumarin. Another compound was isolated from both liquid culture and infested compost.
