Microbial Degradation of Polyaromatic Hydrocarbons
Part of the Microorganisms for Sustainability book series (MICRO,volume 14)
Polycyclic aromatic hydrocarbons (PAHs) belong to the large group of compounds that are composed of multiple aromatic rings. These are found in natural and anthropogenic sources like coal and petrol and can be detected in various environmental compartments, which is a strong concern due to their toxic, cancerogenic, and genotoxic properties. It is crucial to develop methods that would decrease their concentration in water and soils. The most potent degradation of PAHs is usage of microorganisms to biotransform the compounds in situ. In this chapter, the characterization of PAHs is presented. Biodegradation may be performed by bacteria and fungi and also in anaerobic conditions. The factors influencing the biodegradation of PAH are also discussed.
