分枝杆菌SNP 11具有较高的PAH生物降解潜力。在本文中，芘，荧蒽，菲，和他们的死端代谢产物，积累在介质中的分枝杆菌菌株SNP 11的生物降解后的毒性进行了评估，通过筛选电池的急性，慢性和遗传毒性试验。根据对细菌（费氏弧菌、鼠伤寒沙门氏菌菌株TA 1535/pSK 1002、TA 97 a、TA 98、TA 100）、藻类（近头状拟基希内氏菌）和甲壳类动物（大型蚤、可疑网纹蚤）进行的生物测定，在分枝杆菌SNP 11降解PAH后，观察到（基因）毒性潜力完全消失或非常显著降低。
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.
