Pollutants represents an important problem in soil and biosludge.
The object of study is the degradation or accumulation of aromatic substances by mycorrhizal fungi. However, investigations with HPLC showed, that the fungi can metabolize 4-hydroxybenzoic acid and benzoic acid up to concentration of 1 mmol. The accumulation of 3-chlorobenzoic acid by ectomycorrhizal roots depended on the substrate concentration. The highest 3-chlorobenzoic acid concentrations were detected in cell walls of both partners. The results show that mycorrhizal fungi can play an important role in remediation.
