| 2 | Microcystin-LR biodegradation by Sphingopyxis sp.USTB-05显示文摘A promising bacterial strain for biodegradingmicrocystin-LR(MC-LR)as the sole carbon and nitrogensource was successfully isolated from Lake Dianchi,China.The strain was identified as Sphingopyxis sp.USTB-05,which was the first isolated MCs-biodegradingSphingopyxis sp.in China.The average biodegradationrate of MC-LR by Sphingopyxis sp.USTB-05 was 28.8mg·L^(-1)per day,which was apparently higher than those ofother bacteria reported so far.The optimal temperature andpH for both strain USTB-05 growth and MC-LRbiodegradation were 30℃and 7.0,respectively.Therelease of MC-LR from the cyanobacterial cells collectedfrom Lake Guishui and the biodegradation of MC-LR byboth strain and cell-free extract(CE)were investigated.The results indicated that MC-LR with the initialconcentration of 4.0 mg·L^(-1)in water was biodegraded bySphingopyxis sp.USTB-05 within 4 d,while MC-LR withthe initial concentration of 28.8 mg·L^(-1)could be completelyremoved in 3 h by CE of Sphingopyxis sp.USTB-05 containing 350 mg·L^(-1)protein.During enzymaticbiodegradation of MC-LR,two intermediate metabolitesand a dead-end product were observed on an HPLCchromatogram.Moreover,the similar scanning profiles ofMC-LR and its metabolic products indicate that the Addaside-chain of MC-LR was kept intact in all products. | Chengbin XIAO Hai YAN Junfeng WANG Wei WEI Jun NING Gang PAN | 2011 | Frontiers of Environmental Science & Engineering2011，5，4： | 2 |

| 4 | Synergistic removal of aniline by carbon nanotubes and the enzymes of Delftia sp. XYJ6显示文摘Synergistic removal of aniline by carbon nanotubes and the enzymes of Delftia sp. XYJ6, a newly isolated bacterial strain for biodegrading aniline, was investigated. It showed that biodegradation rate of aniline was increased with the augment of protein concentration in cell-free extract of Delftia sp. XYJ6. The adsorption amount of aniline by multi-walled carbon nanotubes (MWCNTs) was slightly higher than that by single-walled carbon nanotubes (SWCNTs), however the adsorption amount of protein of Delftia sp. XYJ6 by MWCNTs was lower than that by SWCNTs. Much more amount of aniline could be removed by CE of Delftia sp. XYJ6 in the presence of SWCNTs than MWCNTs, which indicated that an efficient reaction between aniline and enzymes of Delftia sp. XYJ6 on the surface of SWCNTs played a key role in the rapid enzymatic biodegradation of aniline. This study is not previously reported and may be useful in basic research and the removal of aniline from wastewater. | Hai Yan Xiaojing Yang Jian Chen Chunhua Yin Chengbin Xiao Hao Chen | 2011 | Journal of Environmental Sciences2011，23，7： | 1 |
| 5 | Comparative Assessment on Microstructure and Properties of in-situ TiC+Ti_(5)Si_(3)Reinforced TiAl-Sn-Zr Matrix Composites by Spark Plasma Sintering and Argon Protected Sintering显示文摘The effects of SiC particles(SiCp)on high temperature oxidation behavior of titanium matrix composites(TMCs)under different powder metallurgy processes were investigated.In situ Ti C+Ti_(5)Si_(3)reinforced titanium matrix composites were prepared by discharge plasma sintering(SPS)and argon protective sintering(APS).The results show that the two processes have a negligible effect on the composition and hardness of the samples,but the hardness of the two samples is significantly improved by adding SiCp.The apparent porosity of SPS process is obviously smaller than that of APS process,whereas,the apparent porosity increases slightly with the addition of SiCp.The oxide layer thickness and mass gain of the samples obtained by SPS process are smaller than those obtained by APS process.The oxide thickness and mass gain of both processes are further reduced by adding SiCp.The SPS composites showed the best high temperature oxidation resistance.Therefore,TMCs with Si Cp by SPS can effectively improve the high-temperature oxidation behavior of the materials. | 姚辉 许晓静 CAI Chengbin LI Chen CHEN Fenghua LIU Yangguang XIAO Yishui | 2023 | Journal of Wuhan University of Technology(Materials Science)2023，38，1： | 0 |
| 6 | Nitrate transporter NRT1.1 and anion channel SLAH3 form a functional unit to regulate nitrate-dependent alleviation of ammonium toxicity显示文摘Ammonium(NH_(4)^(+))and nitrate(NO_(3)^(-))are major inorganic nitrogen(N)sources for plants.When serving as the sole or dominant N supply,NH_(4)^(+)often causes root inhibition and shoot chlorosis in plants,known as ammonium toxicity.NO_(3)^(-) usually causes no toxicity and can mitigate ammonium toxicity even at low concentrations,referred to as nitrate-dependent alleviation of ammonium toxicity.Our previous studies indicated a NO_(3)^(-) efflux channel SLAH3 is involved in this process.However,whether additional components contribute to NO_(3)^(-)-mediated NH_(4)^(+)detoxification is unknown.Previously,mutations in NO_(3)^(-) transporter NRT1.1 were shown to cause enhanced resistance to high concentrations of NH_(4)^(+).Whereas,in this study,we found when the high-NH_(4)^(+) medium was supplemented with low concentrations of NO_(3)^(-),nrt1.1 mutant plants showed hyper-sensitive phenotype instead.Furthermore,mutation in NRT1.1 caused enhanced medium acidification under high-NH_(4)^(+)/Iow-NO_(3)^(-) condition,suggesting NRT1.1 regulates ammonium toxicity by facilitating H+uptake.Moreover,NRT1.1 was shown to interact with SLAH3 to form a transporter-channel complex.Interestingly,SLAH3 appeared to affect NO_(3)^(-) influx while NRT1.1 influenced NO_(3)^(-) efflux,suggesting NRT1.1 and SLAH3 regulate each other at protein and/or gene expression levels.Our study thus revealed NRT1.1 and SLAH3 form a functional unit to regulate nitrate-dependent alleviation of ammonium toxicity through regulating NO_(3)^(-) transport and balancing rhizosphere acidification. | Chengbin Xiao Doudou Sun Beibei Liu Xianming Fang Pengcheng Li Yao Jiang Mingming He Jia Li Sheng Luan Kai He | 2022 | Journal of Integrative Plant Biology2022，64，4： | 0 |
| 7 | The characteristics of multi-source mobility datasets and how they reveal the luxury nature of social distancing in the U.S. during the COVID-19 pandemic显示文摘This study reveals the human mobility from various sources and the luxury nature of social distancing in the U.S during the COVID-19 pandemic by highlighting the disparities in mobility dynamics from lower-income and upper-income counties.We collect,process,and compute mobility data from four different sources.We further design a Responsive Index(RI)based on the time series of mobility change percentages to quantify the general degree of mobility-based responsiveness to COVID-19 at the U.S.county level.We find statistically significant positive correlations in the RI between either two data sources,revealing their general similarity,albeit with varying Pearson’s r coefficients.Despite the similarity,however,mobility from each source presents unique and even contrasting characteristics,in part demonstrating the multifaceted nature of human mobility.The results suggest that counties with higher income tend to react more aggressively in terms of reducing more mobility in response to the COVID-19 pandemic.Most states present a positive difference in RI between their upper-income and lower-income counties,where diverging patterns in time series of mobility changes percentages can be found.The findings shed light on not only the characteristics of multi-source mobility data but also the mobility patterns in tandem with the economic disparity. | Xiao Huang Zhenlong Li Yuqin Jiang Xinyue Ye Chengbin Deng Jiajia Zhang Xiaoming Li | 2021 | International Journal of Digital Earth2021，14，4： | 0 |
| 8 | The alleviation of ammonium toxicity in plants显示文摘Nitrogen(N)is an essential macronutrient for plants and profoundly affects crop yields and qualities.Ammonium(NH4+)and nitrate(NO3-)are major inorganic N forms absorbed by plants from the surrounding environments.Intriguingly,NH4+is usually toxic to plants when it serves as the sole or dominant N source.It is thus important for plants to coordinate the utilization of NH4+and the alleviation of NH4+toxicity.To fully decipher the molecular mechanisms underlying how plants minimize NH4+toxicity may broadly benefit agricultural practice.In the current minireview,we attempt to discuss recent discoveries in the strategies for mitigating NH4+toxicity in plants,which may provide potential solutions for improving the nitrogen use efficiency(NUE)and stress adaptions in crops. | Chengbin Xiao Yuan Fang Suomin Wang Kai He | 2023 | Journal of Integrative Plant Biology2023，65，6： | 0 |
