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. (c) 2006 Elsevier Inc. All rights reserved.
