Abstract
The white rot fungus, Pleurotus ostreatus, metabolized four soil adsorbed p
olycyclic aromatic hydrocarbons: 50% of pyrene (0.1 mg g(-1) dry soil), 68%
of anthracene and 63% of phenanthrene were mineralized after 21 d. Biodegr
adation was increased to 75%, 80% and 75%, respectively of the initial conc
entration when 0.15% Tween 40 was added. Biodegradation of pyrene in the pr
esence of surfactant and H2O2 (1.0 mM) was 90%. Benz[a]pyrene was also oxid
ized by Pleurotus ostreatus but it is not mineralized.
