[Acylase activity of mycophilic fungi].

The acylase activity was studied with 65 cultures of mycophilic fungi belonging to 56 species and 33 genera. Among these: 9 species displayed the acylase activity toward ampicillin; 8 species, toward phenoxymethylpenicillin; 6 species, toward benzylpenicillin; and 21 species manifested the complex activity. Many of the active species belonged to the bionecrotrophic group of mycophilic fungi, the number of necrotrophic fungi was less, while that of biotrophs and saprotrophs was even lower.
