Ecotoxicological assessment of PAHs and their dead-end metabolites after degradation by Mycobacterium sp. strain SNP11

Mycobacterium sp. SNP11 has a high PAH biodegradation potential. In this paper, the toxicity of pyrene, fluoranthene, phenanthrene, and their dead-end metabolites, accumulated in the media after biodegradation by Mycobacterium sp. SNP11, were evaluated by a screening battery of acute, chronic, and g...

Description
Summary:Mycobacterium sp. SNP11 has a high PAH biodegradation potential. In this paper, the toxicity of pyrene, fluoranthene, phenanthrene, and their dead-end metabolites, accumulated in the media after biodegradation by Mycobacterium sp. SNP11, were evaluated by a screening battery of acute, chronic, and genotoxic tests. According to the bioassays, performed on bacteria ( Vibrio fischeri, Salmonella typhimurium strains TA1535/pSK1002, TA97a, TA98, TA100), algae ( Pseudokirchneriella subcapitata), and crustaceans ( Daphnia magna, Ceriodaphnia dubia), total disappearance or a very significant reduction of the (geno)toxic potential was observed after PAH degradation by Mycobacterium sp. SNP11.
