| 3 | 烷基化多环芳烃的细菌降解研究进展显示文摘烷基化多环芳烃(alkylated polycyclic aromatic hydrocarbons,A-PAHs)是以多环芳烃(PAHs)为母环,具有烷基侧链的稠环芳香烃,是一类在环境中广泛存在的持久性有机污染物.微生物降解是其在环境中降解去除的主要途径,与真菌、藻类等相比,细菌降解A-PAHs得到更多的关注.本文对APAHs的污染现状及生态毒性,细菌降解甲基萘、甲基菲的研究进展进行了概述,以PAHs的降解酶和降解基因作为参考,总结了A-PAHs可能涉及的降解酶及降解基因.本文有助于了解环境中A-PAHs的生物降解研究现状,为寻找高效的A-PAHs降解方法及减轻其生态风险提供理论依据. | 陈婧 栾天罡 罗丽娟 | 2023 | 环境化学2023，42，1： | 3 |
| 4 | Molecular characterization of methanogenic microbial communities for degrading various types of polycyclic aromatic hydrocarbon显示文摘Knowledge on methanogenic microbial communities associated with the degradation of polycyclic aromatic hydrocarbons(PAHs)is crucial to developing strategies for PAHs bioremediation.In this study,the linkage between the type of PAHs and microbial community structure was fully investigated through 16 S rRNA gene sequencing on four PAH-degrading cultures.Putative degradation products were also detected.Our results indicated that naphthalene(Nap)/2-methylnaphthalene(2-Nap),phenanthrene(Phe)and anthracene(Ant)sculpted different microbial communities.Among them,Nap and 2-Nap selected for similar degrading bacteria(i.e.,Alicycliphilus and Thauera)and methanogens(Methanomethylovorans and Methanobacterium).Nap and 2-Nap were probably activated via carboxylation,producing 2-naphthoic acid.In contrast,Phe and Ant shaped different bacterial and archaeal communities,with Arcobacter and Acinetobacter being Phe-degraders and Thiobacillus Ant-degrader.Methanogenic archaea Methanobacterium and Methanomethylovorans predominated Phe-degrading and Ant-degrading culture,respectively.These findings can improve our understanding of natural PAHs attenuation and provide some guidance for PAHs bioremediation in methanogenic environment. | Quanhui Ye Chengyue Liang Xunwen Chen Tingting Fang Yun Wang Hui Wang | 2019 | Journal of Environmental Sciences2019，31，12： | 3 |
| 5 | Anaerobic phenanthrene biodegradation with four kinds of electron acceptors enriched from the same mixed inoculum and exploration of metabolic pathways显示文摘Polycyclic aromatic hydrocarbons (PAHs) are widespread and persistent contaminants worldwide, especially in environments devoid of molecular oxygen. For lack of molecular oxygen, researchers enhanced anaerobic zones PAHs biodegradation by adding sulfate, bicarbonate, nitrate, and iron. However, microbial community reports of them were limited, and information of metabolites was poor except two-ring PAH, naphthalene. Here, we reported on four phenanthrene-degrading enrichment cultures with sulfate, bicarbonate, nitrate, and iron as electron acceptors from the same initial inoculum. The high-to-low order of the anaerobic phenanthrene biodegradation rate was the nitrate-reducing conditions>sulfate-reducing conditions>methanogenic conditions>iron-reducing conditions. The dominant bacteria populations were Desulfobacteraceae, Anaerolinaceae, and Thermodesulfobiaceae under sulfate-reducing conditions;Moraxellaceae, Clostridiaceae, and Comamonadaceae under methanogenic conditions;Rhodobacteraceae, Planococcaceae, and Xanthomonadaceae under nitrate-reducing conditions;and Geobacteraceae, Carnobacteriaceae, and Anaerolinaceae under iron-reducing conditions, respectively. Principal component analysis (PCA) indicated that bacteria populations of longtime enriched cultures with four electron acceptors all obtained significant changes from original inoculum, and bacterial communities were similar under nitrate-reducing and iron-reducing conditions. Archaea accounted for a high percentage under iron-reducing and methanogenic conditions, and Methanosarcinaceae and Methanobacteriaceae, as well as Methanobacteriaceae, were the dominant archaea populations under iron-reducing and methanogenic conditions. The key steps of phenanthrene biodegradation under four reducing conditions were carboxylation, further ring system reduction, and ring cleavage. | Zuotao Zhang Chongyang Wang Jianzhong He Hui Wang | 2019 | Frontiers of Environmental Science & Engineering2019，13，5： | 3 |
