Biodegradation of Polycyclic Aromatic Hydrocarbons (PAHs) in Petroleum Contaminated Soils
Polycyclic aromatic hydrocarbons are a class of potentially hazardous chemicals of environmental and health concern. PAHs are one of the most prevalent groups of contaminants found in soil. Biodegradation of complex hydrocarbon usually requires the cooperation of more than single specie. In this research biotreatment of PAH (phenanthrene) was studied in a solid-phase reactor using indigenou...
متن کاملEnrichment, isolation, and phylogenetic identification of polycyclic aromatic hydrocarbon-degrading bacteria from Elizabeth River sediments.
The diversity of indigenous bacteria in sediments from several sites in the Elizabeth River (Virginia) able to degrade multiple polycyclic aromatic hydrocarbons (PAHs) was investigated by the use of classical selective enrichment and molecular analyses. Enrichment cultures containing naphthalene, phenanthrene, fluoranthene, or pyrene as a sole carbon and energy source were monitored by denaturi...
متن کاملIdentification of anthraquinone-degrading bacteria in soil contaminated with polycyclic aromatic hydrocarbons.
Quinones and other oxygenated polycyclic aromatic hydrocarbons (oxy-PAHs) are toxic and/or genotoxic compounds observed to be cocontaminants at PAH-contaminated sites, but their formation and fate in contaminated environmental systems have not been well studied. Anthracene-9,10-dione (anthraquinone) has been found in most PAH-contaminated soils and sediments that have been analyzed for oxy-PAHs...
متن کاملIsolation and characterization of a polycyclic aromatic hydrocarbons-degrading enzyme from Xylaria regalis
Twenty-one fungal species were screened for capability of removing pyrene and benzo(a)pyrene in culture. Xylaria regalis was found to show the highest activity. An PAHs-degrading enzyme was purified to homogeneity from the culture mycelium of X. regalis. The crude enzyme was subjected to a series of purification procedures, including QAE Sephadex A-25 anion exchange column, hydrophobic interact...
متن کاملMicrobial degradation of petrochemical waste-polycyclic aromatic hydrocarbons
BACKGROUND Petrochemical industry is one of the fastest growing industries. This industry has immense importance in the growth of economy and manufacture of large varieties of chemicals. The petrochemical industry is a hazardous group of industry generating hazardous waste containing organic and inorganic compounds. In spite of the present treatment process, the hazardous waste compounds are fo...
