Abstract

Polycyclic aromatic hydrocarbons (PAHs) form a group of compounds compused of two or more fused aromatic rings that are carcinogen and mutagenic to human and animals. They are formed by the incomplete combustion of organic matter and fossil fuesl. PAHs are released into the environment along with the wastewater of cokeproducting factories, oil refineries and industrials that use very high temperature. These compounds are also the primary substances used for the production of cosmetics, polymers, highly explosive fertilizer, colours and etc.that are transfer to the environment when used. Today BIODEGRADATION of PAHs by microorganisms is the best way for fending these contamination, and since these bacteria have a variety enzymes, thay are the best microorganisms. Anthracene is tricyclic aromatic hydrocarbon, solid and Phenanthrene isomer. Anthracene is major source for colours such Anthrakinon and Alizarin. It is formed by the incomplete combustion of fossil fuels. In this paper, we isolated the anthracene degrading GRAM NEGATIVE BACTERIA from Maharlu lake. The samples of sediments and water were collected from four sites in Maharlu lake. Samples were filtered and cultured in mineral medium that included inorganic compounds, trace elements and anthracene. After sequential culturing in specialized medium and conducting the biochemical tests, the GRAM NEGATIVE BACTERIA were isolated and the species and genus were identified. The bacteria included Pseudomonas, Vibrio, Nocardia, Aeromonas, and Mycobacterium isolated and characterized as anthracene-degrading bacteria from the lake. Among these bacteria, the highest amount was detected in Khoshk river estury and the least amount was found the central part of the the lake. However, Pseudomonas had the highest dispersal rate and could be used as an anthracenedegrading indicator species.
