| 1 | Metal-dependent anaerobic methane oxidation in marine sediment:insights from marine settings and other systems显示文摘Anaerobic oxidation of methane(AOM) plays a crucial role in controlling global methane emission. This is a microbial process that relies on the reduction of external electron acceptors such as sulfate, nitrate/nitrite, and transient metal ions. In marine settings, the dominant electron acceptor for AOM is sulfate, while other known electron acceptors are transient metal ions such as iron and manganese oxides. Despite the AOM process coupled with sulfate reduction being relatively well characterized,researches on metal-dependent AOM process are few, and no microorganism has to date been identified as being responsible for this reaction in natural marine environments. In this review, geochemical evidences of metal-dependent AOM from sediment cores in various marine environments are summarized. Studies have showed that iron and manganese are reduced in accordance with methane oxidation in seeps or diffusive profiles below the methanogenesis zone. The potential biochemical basis and mechanisms for metal-dependent AOM processes are here presented and discussed. Future research will shed light on the microbes involved in this process and also on the molecular basis of the electron transfer between these microbes and metals in natural marine environments. | Lewen Liang Yinzhao Wang Orit Sivan Fengping Wang | 2019 | Science China(Life Sciences)2019，62，10： | 7 |
| 2 | Widespread Bathyarchaeia encode a novel methyltransferase utilizing lignin-derived aromatics显示文摘Lignin degradation is a major process in the global carbon cycle across both terrestrial and marine ecosystems.Bathyarchaeia,which are among the most abundant microorganisms in marine sediment,have been proposed to mediate anaerobic lignin degradation.However,the mechanism of bathyarchaeial lignin degradation remains unclear.Here,we report an enrichment culture of Bathy-archaeia,named Candidatus Baizosediminiarchaeum ligniniphilus DL1YTT001(Ca.B.ligniniphilus),from coastal sediments that can grow with lignin as the sole organic carbon source under mesophilic anoxic conditions.Ca.B.ligniniphilus possesses and highly expresses novel methyltransferase 1(MT1,mtgB)for transferring methoxyl groups from lignin monomers to cob(I)alamin.MtgBs have no homology with known microbial methyltransferases and are present only in bathyarchaeial lineages.Heterologous expression of the mtgB gene confirmed O-demethylation activity.The mtgB genes were identified in metagenomic data sets from a wide range of coastal sediments,and they were highly expressed in coastal sediments from the East China Sea.These findings suggest that Bathyarchaeia,capable of O-demethylation via their novel and specific methyltransferases,are ubiquitous in coastal sediments. | Tiantian Yu Haining Hu Xianhong Zeng Yinzhao Wang Donald Pan Longhui Deng Lewen Liang Jialin Hou Fengping Wang | 2023 | mLife2023，2，3： | 0 |
| 3 | Numerical Simulation of Boundary Layer with Spectral Method显示文摘It is important to improve the speed of a ship,the friction resistance can be reduced by injection air at the bottom of a ship when the ship is running on the water.As the first part of the studying project,here numerical simulation study method,boundary condition and governing equations are presented.It is easy to study complicated problems from simple conditions,so the program concerning boundary layer condition is compiled to solve the problem.Here the spectral method is introduced,and the results are tested by Dorod’s results. | Zhiyong Liang Lewen Zhang Xianfu Wang(Wuhan Transportation University,Wuhan 430063, P.R.China) | 1999 | 武汉理工大学学报(交通科学与工程版)1999，24，S1： | 0 |
