COMPARISON OF THE TOXICITY OF VARIOUS LIGNIN-RELATED PHENOLIC-COMPOUNDS TOWARD SELECTED FUNGI PERFECTI AND FUNGI IMPERFECTI

A selection of 88 micromycetes belonging to various taxonomic groups w as grown on malt-agar medium containing different lignin-related pheno lic compounds (ferulic, protocatechuic, syringic and vanillic acids, c atechol, guaiacol, and phenol) at concentrations ranging from 100 to 1 000 mg/liter. Growth and morphological changes mere recorded after 15 days of incubation. Behavior of fungi in contact with the different ph enolics were compared. Some strains were very sensitive and might cons titute specific or general bioindicators of pollution. The relationshi ps between origin of isolates or constitutive phenoloxidase activity a nd resistance or sensitivity of fungi to phenolics were researched. No evidence of implication of these two parameters was found. (C) 1995 A cademic Press, Inc.
