How Soil Microbial Communities from Industrial and Natural Ecosystems Respond to Contamination by Polycyclic Aromatic Hydrocarbons

Soil microbial community plays a major role in removal of polycyclic aromatic hydrocarbons (PAHs) from soil, and bioremediation potentially offers an attractive economic approach to the clean-up polluted areas. To evaluate contribution different groups soil PAH degradation, enzymatic activity phospholipid fatty acids (PLFAs) were analysed mesocosm trial three soils (two natural one industrial) artificially contaminated with 3- 5-rings PAHs. The Metabolic Activity Index (MAI) was applied investigate stability, terms resistance resilience. Gram+ Gram- bacteria predominant all types. In first stage incubation, fungi industrial followed by mycorrhizae actinomycetes, indicating their stimulation after addition. two soils, several predominant: actinomycetes one, other, response contamination. Regarding MAI calculated on activities, showed neither resistant nor resilient respect other soil. Our results highlight that changes its composition then physiological functions according land use as result
