| 1 | Evaluating the flavor and divergent bacterial communities in corn-based zha-chili显示文摘Zha-chili is a naturally fermented traditional food from central southern China.Corn-based zha-chili is one of the most popular varieties with a special flavor.To investigate its distinct microbiome,corn-based zha-chili samples were collected and investigated using both high-throughput sequencing and culture-dependent method.Subsequently,E-nose and E-tongue sensors were used to evaluate the overall sensory profile.We found that the bacterial communities present in zha-chili samples from the two regions were significantly different(P<0.05).Companilactobacillus,Lactiplantibacillus,and Corynebacterium were found to be the dominant genera common to samples from both regions.Among these,lactic acid bacteria were the most dominant.Biomarker genera were Ligilactobacillus,Lactobacillus,and Levilactobacillus(Huaihua)and Pantoea,Lactiplantibacillus,and Weissella(Songtao).Using culture-dependent methods,the most dominant genus Companilactobacillus was found to comprise Companilactobacillus alimentarius and Companilactobacillus futsaii.The sensory profile was also characterized.This indicated that zha-chili from the two regions could be discriminated by sourness and aftertaste-B(E-taste),and W1C,W3C,W5C,W1S,W2S,W5S,and W2W(E-nose).Correlation analysis suggested that the dominant genera might not affect the aroma quality of corn-based zha-chili,whereas they were related to taste quality.Levilactobacillus and Ligilactobacillus were positively correlated with the characteristic taste indices and negatively correlated with the off-flavor indices.Another dominant genus,Kocuria was positively correlated with umami and richness(P<0.05).Our results could provide a basis for supporting zha-chili production and help the isolation of appropriate lactic acid bacteria from corn-based zha-chili. | Zhuang Guo Yurong Wang Fanshu Xiang Yun Dong Qiangchuan Hou Zhendong Zhang | 2022 | Food Bioscience2022，46，2： | 6 |
| 2 | China’s Recent Progresses in Polar Climate Change and Its Interactions with the Global Climate System显示文摘During the recent four decades since 1980,a series of modern climate satellites were launched,allowing for the measurement and record-keeping of multiple climate parameters,especially over the polar regions where traditional observations are difficult to obtain.China has been actively engaging in polar expeditions.Many observations were conducted during this period,accompanied by improved Earth climate models,leading to a series of insightful understandings concerning Arctic and Antarctic climate changes.Here,we review the recent progress China has made concerning Arctic and Antarctic climate change research over the past decade.The Arctic temperature increase is much higher than the global-mean warming rate,associated with a rapid decline in sea ice,a phenomenon called the Arctic Amplification.The Antarctic climate changes showed a zonally asymmetric pattern over the past four decades,with most of the fastest changes occurring over West Antarctica and the Antarctic Peninsula.The Arctic and Antarctic climate changes were driven by anthropogenic greenhouse gas emissions and ozone loss,while tropical-polar teleconnections play important roles in driving the regional climate changes and extreme events over the polar regions.Polar climate changes may also feedback to the entire Earth climate system.The adjustment of the circulation in both the troposphere and the stratosphere contributed to the interactions between the polar climate changes and lower latitudes.Climate change has also driven rapid Arctic and Southern ocean acidification.Chinese researchers have made a series of advances in understanding these processes,as reviewed in this paper. | Xichen LI Xianyao CHEN Bingyi WU Xiao CHENG Minghu DING Ruibo LEI Di QI Qizhen SUN Xiaoyu WANG Wenli ZHONG Lei ZHENG Meijiao XIN Xiaocen SHEN Chentao SONG Yurong HOU | 2023 | Advances in Atmospheric Sciences2023，40，8： | 1 |

| 4 | Insights into simultaneous adsorption and oxidation of antimonite[Sb(III)]by crawfish shell-derived biochar:spectroscopic investigation and theoretical calculations显示文摘Removal of antimonite[Sb(Ⅲ)]from the aquatic environment and reducing its biotoxicity is urgently needed to safeguard environmental and human health.Herein,crawfish shell-derived biochars(CSB),pyrolyzed at 350,500,and 650℃,were used to remediate Sb(Ⅲ)in aqueous solutions.The adsorption data best fitted to the pseudo-second-order kinetic and Langmuir isotherm models.Biochar produced at 350℃(CSB350)showed the highest adsorption capacity(27.7 mg g^(−1)),and the maximum 78%oxidative conversion of Sb(Ⅲ)to Sb(V).The adsorption results complemented with infrared(FTIR),X-ray photoelectron(XPS),and near-edge X-ray absorption fine structure(NEXAFS)spectroscopy analyses indicated that the adsorption of Sb(Ⅲ)on CSB involved electrostatic interaction,surface complexation with oxygen-containing functional groups(C=O,O=C-O),π-πcoordination with aromatic C=C and C-H groups,and H-bonding with-OH group.Density functional theory calculations verified that surface complexation was the most dominant adsorption mechanism,whilstπ-πcoordination and H-bonding played a secondary role.Furthermore,electron spin resonance(ESR)and mediated electrochemical reduction/oxidation(MER/MEO)analyses confirmed that Sb(Ⅲ)oxidation at the biochar surface was governed by persistent free radicals(PFRs)(•O_(2)^(−)and•OH)and the electron donating/accepting capacity(EDC/EAC)of biochar.The abundance of preferable surface functional groups,high concentration of PFRs,and high EDC conferred CSB350 the property of an optimal adsorbent/oxidant for Sb(Ⅲ)removal from water.The encouraging results of this study call for future trials to apply suitable biochar for removing Sb(Ⅲ)from wastewater at pilot scale and optimize the process. | Hanbo Chen Yurong Gao Jianhong Li Chenghua Sun Binoy Sarkar Amit Bhatnagar Nanthi Bolan Xing Yang Jun Meng Zhongzhen Liu Hong Hou Jonathan WCWong Deyi Hou Wenfu Chen Hailong Wang | 2022 | Biochar2022，4，1： | 0 |
| 5 | Uncertainties of ENSO-related Regional Hadley Circulation Anomalies within Eight Reanalysis Datasets显示文摘El Nino-Southern Oscillation(ENSO),the leading mode of global interannual variability,usually intensifies the Hadley Circulation(HC),and meanwhile constrains its meridional extension,leading to an equatorward movement of the jet system.Previous studies have investigated the response of HC to ENSO events using different reanalysis datasets and evaluated their capability in capturing the main features of ENSO-associated HC anomalies.However,these studies mainly focused on the global HC,represented by a zonal-mean mass stream function(MSF).Comparatively fewer studies have evaluated HC responses from a regional perspective,partly due to the prerequisite of the Stokes MSF,which prevents us from integrating a regional HC.In this study,we adopt a recently developed technique to construct the three-dimensional structure of HC and evaluate the capability of eight state-of-the-art reanalyses in reproducing the regional HC response to ENSO events.Results show that all eight reanalyses reproduce the spatial structure of HC responses well,with an intensified HC around the central-eastern Pacific but weakened circulations around the Indo-Pacific warm pool and tropical Atlantic.The spatial correlation coefficient of the three-dimensional HC anomalies among the different datasets is always larger than 0.93.However,these datasets may not capture the amplitudes of the HC responses well.This uncertainty is especially large for ENSO-associated equatorially asymmetric HC anomalies,with the maximum amplitude in Climate Forecast System Reanalysis(CFSR)being about 2.7 times the minimum value in the Twentieth Century Reanalysis(20CR).One should be careful when using reanalysis data to evaluate the intensity of ENSO-associated HC anomalies. | Yadi LI Xichen LI Juan FENG Yi ZHOU Wenzhu WANG Yurong HOU | 2024 | Advances in Atmospheric Sciences2024，41，1： | 0 |
| 6 | Mechanism of blood coagulation in common carp (Cyprinus carpio)显示文摘In vitro,carp blood was anticoagulated by using MgSO4 at a final concentration of 22.2 mmol L-1 and sodium citrate at a final concentration of 11.8 mmol L-1.The coagulation times for carp plasma diluted by ion-free water(1:1),and that of carp plasma to which thrombocytes and small lymphocytes were added,were measured at 23℃ using standard methods,and then contrasted with the coagulation times for plasma obtained from chickens and rabbits.The shapes of the thrombocytes and small lymphocytes,which were either wet mounted or stained with hematoxylin and eosin,were observed under a light microscope.We found that:(i)the coagulation reaction of carp blood was significantly(P<0.01)accelerated by the addition of ion-free water;(ii)the three types of blood cells(thrombocytes,small lymphocytes and red blood cells)promoted plasma coagulation to a similar extent(P>0.05);(iii)in carp Mg^(2+)plasma and K_(2)C_(2)O_(4) plasma,the thrombocytes were usually morphologically normal,but many small lymphocytes were destroyed and became aggregated;(iv)in the citrate plasma,thrombocytes were often aggregated,but the small lymphocytes were usually morphologically normal;and(v)the coagulation time for chicken and rabbit plasma was significantly extended by adding ion-free water. | Shuangan LI Yuzhi LIU Guoxian ZHAO Junjie LI Jianhua HOU Ming GAO Yurong LI | 2006 | Integrative Zoology2006，1，3： | 0 |
