Biodegradation of polycyclic aromatic hydrocarbons

Bioremediation of Oil on Shoreline Environments: Development of Techniques and Guidelines

“…There are two main approaches to oil-spill bioremediation: [1] Bioaugmentation (seeding) involves the addition of oil-degrading bacteria to supplement the existing microbial population; and [2] Biostimulation involves the addition of nutrients or other growth-enhancing cosubstrates to stimulate the growth of indigenous oil degraders.…”

“…Bacteria and fungi, with the capability to degrade a wide range of oil components, have been found to exist throughout the marine ecosystem [2,3]. Studies on the fate of petroleum following marine oil spills have shown that the natural rates of hydrocarbon biodegradation are usually limited by abiotic environmental factors [4].…”

Evaluation of the interaction between biodegradation and sorption of phenanthrene in soil-slurry systems

“…Bioremediation of hazardous hydrophobic organic compounds, such as polycyclic aromatic hydrocarbons (PAHs), is a major environmental concern due to their toxic and carcinogenic properties (Cerniglia, 1992;Keith and Telliard, 1979). These compounds are released into the environment as a result of incomplete combustion of fossil fuels or by accidental discharge during the transport, use, and disposal of petroleum products (Cerniglia, 1992).…”

“…These compounds are released into the environment as a result of incomplete combustion of fossil fuels or by accidental discharge during the transport, use, and disposal of petroleum products (Cerniglia, 1992). Due to their hydrophobicity, the hydrophobic organic compounds are mainly associated with the soil organic matter or non-aqueous-phase liquids.…”

Degradation of polycyclic aromatic hydrocarbons by newly isolated Curvularia sp. F18, Lentinus sp. S5, and Phanerochaete sp. T20

“…However, if this hypothesis is correct, these metabolites would probably be the PAH-quinone compounds, which, in general, are the products of PAHs degradation by white rot fungi including Lentinus via the ligninolytic and laccase enzymatic reactions 42 . In the case of complete mineralization, this PAH-quinone will pass the ring fission process and produce CO 2 as the final product 44 . Phanerochaete sp.…”
