Removal of Polycyclic Aromatic Hydrocarbons by Pleurotus ostreatus sp. ATCC38540 in Liquid Medium
نویسنده
چکیده
Biodegradation of polycyclic aromatic hydrocarbons (PAHs) in crude oil, by a white rot fungus, Pleurotus ostreatus sp., in broth culture was investigated. It was found that the biomass of the organism increased with the increase of PAHs concentration in the cultures. In the cultures with 25.99, 49.01 and 80.05 mg.kg-1 PAHs, the degradation increased with the PAHs of low molecular weight concentration, whereas, the degradation was high and constant for high molecular weight. The addition of Tween 80 improved the ability to degrade PAHs high molecular weight. In conclusion, P. ostreatus is a promising white rot fungus to used degrade PAHs of low and high molecular weight in the environment.

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 t...
متن کاملInfluence of PAHs on ligninolytic enzymes
Polycyclic aromatic hydrocarbons (PAHs), their derivatives, and their degradation products were assayed for the ability to enhance activities of ligninolytic enzymes (laccase and versatile peroxidase) of the fungus Pleurotus ostreatus D1. The activities of both laccase and versatile peroxidase were induced by the PAHs, their derivatives, and their degradation products. Laccase was produced most...

Abstract Polycyclic aromatic hydrocarbons (PAHs) are classified as persistent and carcinogenic organic pollutants. PAHs contamination has been reported in water. Many of relevant regulatory bodies such as EU and EPA have regulated the limit levels for PAHs in drinking water. In this study, 13 priority polycyclic aromatic hydrocarbons (PAHs) were determined in tap water samples of Tehran and wat...
