Pu-erh tea， a traditional.Chinese beverage， performs an anti-obesity function， but the correl.tion between its components and efficacy remains unknown. Here， we screened two Pu-erh teas with significant anti-obesity efficacies from 11 teas. In vitro experiments reveal.d that l.pid accumul.tion in l.2 cel.s and l.pid synthesis in 3T3-l. cel.s were significantl. better inhibited by Tea-B than Tea-A. Further in vivo experiments using model.mice reveal.d that the differences in chemical.components generated two pathways in the anti-obesity efficacy and mechanism of Pu-erh teas. Tea-A changes the histomorphol.gy of brown adipose tissue (BAT) and increases the abundance of Coriobacteriaceae＿UCG＿002 and cycl.c AMP in guts through high chemical.contents of cycl.pentasil.xane， decamethyl. tridecane and 1，2，3-trimethoxybenzene， eventual.y increasing BAT activation and fat browning gene expression; the high content of hexadecane and 1，2-dimethoxy-benzene in Tea-B reduces white adipose tissue (WAT) accumul.tion and the process of fatty l.ver， increases the abundance of Odoribacter and sphinganine 1-phosphate， inhibits the expression of l.pid synthesis and transport genes. These mechanistic findings on the association of the representative bioactive components in Pu-erh teas with the anti-obesity phenotypes， gut microbes， gut metabol.te structure and anti-obesity pathways， which were obtained for the first time， provide foundations for devel.ping functional.Pu-erh tea.

采用吸附法降低水体中磷酸盐浓度是目前治理和控制水体富营养化的常见手段之一.生物炭(BC)作为一种廉价的化学稳定型吸附材料,尤其适用于对阳离子型污染物的吸附与去除,但生物炭表面负电性和有限的吸附位点限制了其对磷酸盐的吸附性能.本研究使用球磨法将氧化铁负载于玉米秸秆生物炭得到一种具备高效除磷性能的复合材料.使用X射线衍射光谱仪、扫描电子显微镜、氮气吸附-解吸、傅里叶红外光谱仪、X射线电子能谱、Zeta电位仪对复合材料进行了表征检测,采用系列批次实验考察了材料对水溶液中正磷酸盐(PO_(4)^(3-))的吸附性能和吸附机制.结果表明,球磨处理成功将氧化铁(Fe_(2)O_(3))负载至生物炭表面,极大地提高了生物炭比表面积(210 m^(2)·g^(-1))、Zeta电势和含氧官能团种类和数量.溶液初始pH和吸附剂投加量是影响磷酸盐去除率的关键因素.l.ngmuir方程能更好地拟合等温吸附过程:当溶液pH=5.0,投加量为2.0 g·l.(-1)时,制备的球磨氧化铁改性生物炭达到对磷酸盐的理论最大吸附量(45.03 mg·g^(-1)).吸附动力学过程更加符合假二级动力学方程,表明化学过程主导整个吸附过程.共存离子(Cl.(-)、NO_(3)^(-)和SO_(4)^(2-))对磷酸盐吸附性能的影响可忽略不计.连续6次的吸附-解吸实验结果说明球磨氧化铁负载生物炭具备较好的化学稳定性和可循环使用性.系列表征分析结果显示:主要的吸附机制包括表面络合、金属-磷桥接和配位吸附.本研究为水体中磷素控制提供了一种可行策略,也为高效吸附材料的制备提供了新的思路.

The use of transition metal.activated peroxymonosul.ate（PMS） as an advanced oxidation technol.gy has gained recognition. This study devel.ped a catal.st using cobal.Dl.nthanum bimetal.ic oxide supported on l.yered mol.bdenum disul.ide （Mo S2） as a carrier. The CoDl./Mo S2catal.st was synthesised through coprecipitation, fol.owed by cal.ination with an optimised metal.ratio of Co:l.=2:1 to activate PMS and degrade trace chl.ramphenicol.CAP） in water. The chemical.composition of the catal.st was confirmed using X-ray diffraction （XRD） and X-ray photoel.ctron spectroscopy （XPS）. At catal.st and PMS dosages of 0.1 and 0.5 g·l.1, respectivel., the degradation rate of CAP was 95% with in 30 min. The catal.st exhibitedstrong resistance to most interfering anions and maintained a high degradation rate at p H 3D11. l.quid chromatographyDmass spectrometry anal.sis reveal.d the potential.degradation pathways of CAP in the CoDl./Mo S2（2:1）/PMS system. For other pol.utants, such as oxytetracycl.ne,compl.te degradation was achieved within 20 min,demonstrating the broad appl.cabil.ty of the CoDl./Mo S2（2:1）/PMS system for the degradation and removal.of antibiotic organic contaminants. This study offers a feasibl. approach for the degradation of antibiotic organic pol.utants, incl.ding CAP, in natural.water bodies.
