ABSTRACT
A selection of 39 strains of micromycetes known as good degraders of polychlorinated aromatic compounds, mostly isolated from soil and belonging to various taxonomic groups, have been investigated for anthracene degradation. Toxicity and consumption assays, first evaluated on solid media, have not shown any toxicity of anthracene (1-100 mg.L-1) towards fungi. Degradation of anthracene (10 mg.L-1) was then investigated in a liquid synthetic medium for 4 days and evaluated by HPLC. Among the 39 strains tested, 19 degraded anthracene at 50% or more. Zygomycetes appeared to be the most efficient group (mean degradation : 81%) while Melanconiales were the least efficient (mean: 14%). Among 19 efficient strains, 8 had not yet been reported in the literature: Cryphonectria parasitica, Ceriporiopsis subvermispora, Oxysporus sp., Cladosporium herbarum, Drechslera spicifera, Verticillium lecanii, Fusarium moniliforme var. subglutinans and Rhizopus arrhizus.
