Abstract

Polycyclic aromatic hydrocarbons (PAHs) such as anthracene, naphthalene, and phenanthren are the most toxic and carcinogenic pollutants which cause severe damages on soil and water resources. In order to remove these materials, biological methods and using potential of local microorganisms of oil contaminated soils are preferred because of cheapness and availability. Existing SOIL MICROORGANISMS use these hydrocarbons as carbon and energy and finally produce water, CO2, biomass, and harmless material sources. In the present study, the sampling was conducted from different points in soil of Tabriz and oil-polluted soils from oil materials of Tabriz refinery. The samples were cultured microbial in YGM and starch case in agar. About 100 microbial colonies and isolations were obtained. 1000 mg/l of anthracene hydrocarbons were obtained in Muller Hilton broth, and then fixed amounts of these bacteria were added separately. They were treated and incubated by shaker in 130 RPM, at 28oC for one week. The rate of mentioned hydrocarbons’ destruction was evaluated by the spectrophotometer that determined reliability of primary aromatic compounds by TLC method. Up to 90 anthracene reducing bacteria were isolated that their destroying rates were 3.4-82.6%. Some samples from secondary metabolites of each hydrocarbon which had the most destroying percentage were under GC-Mass analysis in order to be identified. Then, some toxic-free mediatory substances were obtained because of anthracene biological reduction. By improving the growth and proliferation of effective bacteria and identifying obtained metabolites, it can be possible to clear polluted spoils from PAHSs and to produce useful metabolites and other harmless materials in semi-industrial and practical pilots.
