ABSTRACT The white-rot fungus Pleurotus ostreatus was able to degrade the polycyclic aromatic hydrocarbons (PAHs) benzo[a]anthracene, chrysene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[a]pyrene, dibenzo[a,h]anthracene, and benzo[ghi]perylene in nonsterile soil both in the presence and in the absence of cadmium and mercury. During 15 weeks of incubation, recovery of individual compounds was 16 to 69% in soil without additional metal. While soil microflora contributed mostly to degradation of pyrene (82%) and benzo[a]anthracene (41%), the fungus enhanced the disappearance of less-soluble polycyclic aromatic compounds containing five or six aromatic rings. Although the heavy metals in the soil affected the activity of ligninolytic enzymes produced by the fungus (laccase and Mn-dependent peroxidase), no decrease in PAH degradation was found in soil containing Cd or Hg at 10 to 100 ppm. In the presence of cadmium at 500 ppm in soil, degradation of PAHs by soil microflora was not affected whereas the contribution of fungus was negligible, probably due to the absence of Mn-dependent peroxidase activity. In the presence of Hg at 50 to 100 ppm or Cd at 100 to 500 ppm, the extent of soil colonization by the fungus was limited.

Indonesia is a tropical country and the richest country in the world for biodiversity, including fl ora and fauna, invertebrates, phytoplankton, bacteria, and huge number of fungus such as mushrooms, molds, mildews and smuts. White rot fungi is one of the ubiquitous creatures in Indonesia. Results indicated that white rot fungus has ability to degrade successfully some organic pollutansin the environment, such as polycyclic aromatic hydrocarbons (PAH), Polychlorinated Biphenyls (PCB’s), Trinitrotoluence (TNT), and DDT. This organism has ability to release intra and extra-cellular enzymes. There are three important rules in these degradation processes, called lignin modifi ed enzymes (LME’s) including Lignin peroxidase, Mn-dependent peroxidase and Laccase. White rot fungi contains all three enzymes and able to breakdown and mineralize several environmental pollutants into non toxic forms. This paper discuss several processes responsible for this degradation.Key words: White rot fungi, bioremediation, lignin modifi ed enzymes, persistent organic pollutants.
