Characterization of a phenanthrene-degrading methanogenic community

Quanhui Ye, Chengyue Liang, Chongyang Wang, Yun Wang, Hui Wang

《环境科学与工程前沿（英文）》 2018年第12卷第5期 doi: 10.1007/s11783-018-1083-2

摘要：

The mixed samples of contaminated soil, sludge and coke wastewater showed great phenanthrene methanogenic degradation potential.

Comamonadaceae, Nocardiaceae and Methanobacterium were dominant members.

Hexane, hexadecane and benzene could enhance phenanthrene degradation.

Acid resistance of methanogenic bacteria in a two-stage anaerobic process treating high concentration

ZHOU Xuefei, REN Nanqi

《环境科学与工程前沿（英文）》 2007年第1卷第1期页码 53-56 doi: 10.1007/s11783-007-0010-8

摘要： In this study, the two-stage upflow anaerobic sludge blanket (UASB) system and batch experiments were employed to evaluate the performance of anaerobic digestion for the treatment of high concentration methanol wastewater. The acid resistance of granular sludge and methanogenic bacteria and their metabolizing activity were investigated. The results show that the pH of the first UASB changed from 4.9 to 5.8 and 5.5 to 6.2 for the second reactor. Apparently, these were not the advisable pH levels that common methanogenic bacteria could accept. The methanogenic bacteria of the system, viz. Methanosarcina barkeri, had some acid resistance and could still degrade methanol at pH 5.0. If the methanogenic bacteria were trained further, their acid resistance would be improved somewhat. Granular sludge of the system could protect the methanogenic bacteria within its body against the impact of the acidic environment and make them degrade methanol at pH 4.5. The performance of granular sludge was attributed to its structure, bacteria species, and the distribution of bacterium inside the granule.

Effect of 2-butenal manufacture wastewater to methanogenic activity and microbial community

Guangqing Song, Hongbo Xi, Xiumei Sun, Yudong Song, Yuexi Zhou

《环境科学与工程前沿（英文）》 2018年第12卷第5期 doi: 10.1007/s11783-018-1056-5

摘要：

The inhibition ratio sharply increased with the increasing COD.

The absorbance of UV-vis at 420 nm showed a linear correlation with the SMA.

The molecular structure of EPS has changed when COD was 9585 mg/L.

Illumina Miseq sequencing was employed to reveal the microbial composition.

Methanogenic community structure in simultaneous methanogenesis and denitrification granular sludge

Yujiao Sun, Juanjuan Zhao, Lili Chen, Yueqiao Liu, Jiane Zuo

《环境科学与工程前沿（英文）》 2018年第12卷第4期 doi: 10.1007/s11783-018-1067-2

摘要：

• UASB with SMD granules was operated with high removal efficiency of COD and NO₃^--N.

• Methanosaetaceae was absolute predominant methanogen in SMD granules.

• The methanogen quantity and activity decreased as C/N decreased from 20:1 to 5:1.

• Bacterial community succession happened with C/N decreasing.

摘要：

针对石油烃污染的厌氧环境, 利用微生物的代谢作用将石油烃转化为甲烷是一种潜在的生物修复策略。然而, 目前对于微生物厌氧烃降解产甲烷的机制尚不清楚。经过十年的持续富集和转接培养, 我们获得了一种能够降解正构烷烃 (C₁₅~C₂₀) 并且产甲烷富集培养体系, 并且经过转接培养该培养物在甲烷生产的动力学特性方面得到了持续的提高。综合宏基因组和宏转录组的分析结果, 发现正构烷烃主要通过Desulfosarcinaceae、Firmicutes和Synergistetes菌通过富马酸加成的方式进行起始活化, 然后在Tepidiphilus菌的协同作用下进一步降解。同时, 体系中含量较多的Anaerolineaceae菌主要负责死细胞生物质的回收。根据宏转录组学分析结果, 甲烷主要通过H₂依赖型的甲基营养甲烷途径产生, 主要由候选门Verstraetearchaeta内的Methanomethyliaceae通过利用死细胞生物质回收代谢过程中产生的三甲胺来产生甲烷。这些发现表明, 依赖H2的甲基营养产甲烷菌以及甲基营养产甲烷菌可能在含石油烃的地下生态系统的碳循环过程中发挥着重要的作用。
