| 2 | Physicochemical properties and volatile components of pea flour fermented by Lactobacillus rhamnosus L08显示文摘Pea(Pisum sativum L.)is an important source of plant proteins.However,the use of pea flour as a food ingredient is greatly limited due to its strong beany flavor.In this work,we investigated the effects of Lactobacillus rhamnosus L08(L.rhamnosus L08)fermentation on the physicochemical characteristics,amino acids composition and volatile flavor compounds of pea flour.We found that L.rhamnosus L08 had the probiotic potential of utilizing pea flour as fermentation substrate.L.rhamnosus L08 fermentation significantly increased the content of most amino acids,and total amino acid content increased from 222.18 mg/g at 0 h to 262.35 mg/g at 6 h.A total of 44 volatile compounds were identified in pea flour.L.rhamnosus L08 fermentation increased the variety of acids and esters,while reduced the unpleasant flavor such as nonanal,decanal,octanal,1-hexanol and 2-ethyl-1-hexanol.The emulsifying stability and foam stability of pea flour were slightly enhanced during fermentation.Our results illustrate that lactic acid bacteria fermentation is a promising approach to eliminate undesirable aroma of pea flour.Moreover,this study provides theoretical support for the application of peas as high-quality protein source. | Mengqi Pei Zifu Zhao Song Chen E.I.Reshetnik S.L.Gribanova Chun Li Guofang Zhang Libo Liu Lin Zhao | 2022 | Food Bioscience2022，46，2： | 2 |
| 3 | A spatiotemporal data collection of viral cases for COVID-19 rapid response显示文摘Under the global health crisis of COVID-19,timely,and accurate epi-demic data are important for observation,monitoring,analyzing,modeling,predicting,and mitigating impacts.Viral case data can be jointly analyzed with relevant factors for various applications in the context of the pandemic.Current COVID-19 case data are scattered across a variety of data sources which may consist of low data quality accompanied by inconsistent data structures.To address this short-coming,a multi-scale spatiotemporal data product is proposed as a public repository platform,based on a spatiotemporal cube,and allows the integration of different data sources by adopting various data standards.Within the spatiotemporal cube,a comprehensive data processing workflow gathers disparate COVID-19 epidemic data-sets at the global,national,provincial/state,county,and city levels.This proposed framework is supported by an automatic update with a 2-h frequency and the crowdsourcing validation team to produce and update data on a daily time step.This rapid-response dataset allows the integration of other relevant socio-economic and environ-mental factors for spatiotemporal analysis.The data is available in Harvard Dataverse platform(http://gffzz9c54d31c51204187sucb5wf5xvnf06o0w.ffgz.tsg.suse.edu.cn/dataset.xhtml?persistentId=doi:10.7910/DVN/8HGECN)and GitHub open source repository(http://gffzz188fe103f8f1460asucb5wf5xvnf06o0w.ffgz.tsg.suse.edu.cn/stccenter/COVID-19-Data). | Dexuan Sha Yi Liu Qian Liu Yun Li Yifei Tian Fayez Beaini Cheng Zhong Tao Hu Zifu Wang Hai Lan You Zhou Zhiran Zhang Chaowei Yang | 2021 | Big Earth Data2021，5，1： | 2 |
| 4 | Taking the pulse of COVID-19:a spatiotemporal perspective显示文摘The sudden outbreak of the Coronavirus disease(COVID-19)swept across the world in early 2020,triggering the lockdowns of several billion people across many countries,including China,Spain,India,the U.K.,Italy,France,Germany,Brazil,Russia,and the U.S.The transmission of the virus accelerated rapidly with the most confirmed cases in the U.S.,India,Russia,and Brazil.In response to this national and global emergency,the NSF Spatiotemporal Innovation Center brought together a taskforce of international researchers and assembled implementation strategies to rapidly respond to this crisis,for supporting research,saving lives,and protecting the health of global citizens.This perspective paper presents our collective view on the global health emergency and our effort in collecting,analyzing,and sharing relevant data on global policy and government responses,human mobility,environmental impact,socioeconomical impact;in developing research capabilities and mitigation measures with global scientists,promoting collaborative research on outbreak dynamics,and reflecting on the dynamic responses from human societies. | Chaowei Yang Dexuan Sha Qian Liu Yun Li Hai Lan Weihe Wendy Guan Tao Hu Zhenlong Li Zhiran Zhang John Hoot Thompson Zifu Wang David Wong Shiyang Ruan Manzhu Yu Douglas Richardson Luyao Zhang Ruizhi Hou You Zhoua Cheng Zhong Yifei Tian Fayez Beaini Kyla Carte Colin Flynn Wei Liu Dieter Pfoser Shuming Bao Mei Li Haoyuan Zhang Chunbo Liu Jie Jiang Shihong Du Liang Zhao Mingyue Lu Lin Li Huan Zhou Andrew Ding | 2020 | International Journal of Digital Earth2020，13，10： | 2 |

| 7 | Properties and applications of biochars derived from different biomass feedstock sources显示文摘In China,substantial agricultural and garden wastes are burned yearly.This practice not only wastes resources but also pollutes air.Corn straw and poplar leaves are typical agricultural and garden waste in China.In this study,corn straw and poplar leaves were used to prepare biochars with different pyrolysis temperatures(250℃,350℃,450℃,550℃and 650℃)and were labeled as CC(corn straw)and LC(poplar leaves),respectively.The biochars were characterized through elemental analysis,Brunauer-Emmett-Teller surface area analysis,scanning electron microscopy and Fourier transform infrared spectroscopy.Yield,ash content and biochar pH were also measured.Results showed that the two biochars possessed some similar characteristics with increasing pyrolysis temperature.These attributes included increased carbon content,biochar hydrophobicity,alkaline pH;decreased hydrogen and oxygen contents and polar functional group content;and enlarged surface area.The biochars also displayed some different characteristics,such as the obviously larger surface area of CC than that of LC at high pyrolysis temperatures and the regular holes of CC and irregular and disordered holes of LC.When biochars CC-650 and LC-650 were used as soil conditioners,the soil pH increased by 0.3 and 0.4 units,respectively,and the soil cation exchange capacity increased by 12.7%and 21.5%,respectively,with respect to those of the blank controls. | Bai Xiaofeng Zhou Xiaoqin Li Zifu Ni Jiewen Bai Xue | 2017 | International Journal of Agricultural and Biological Engineering2017，10，2： | 1 |
| 8 | Online measurement of alkalinity in anaerobic co-digestion using linear regression method显示文摘Alkalinity is a reliable indicator of process stability in anaerobic digestion system.Total alkalinity(TA)and partial alkalinity(PA)are usually monitored offline as indicators for the status of anaerobic digestion process.In order to online monitor TA and PA,the linear regression method was used as estimator to predict alkalinity via software sensor method.Parameters,namely,pH,oxidation and reduction potential(ORP),and electrical conductivity(EC),were used as input variables.EC was the most significant parameter with TA and PA.Multiple linear regression(MLR)models and simple linear regression models with EC were constructed to predict TA and PA in anaerobic co-digestion system.On the basis of the evaluation of prediction accuracy,the applications of linear regression models were better for monitoring PA than TA.MLR models provided higher accuracy for alkalinity prediction than simple linear regression models.The two MLR models based on single-phase anaerobic digestion system were also feasible to predict TA in anaerobic co-digestion systems.However,the accuracy of these models should be improved by calibrating for broad applications of linear regression method in online alkalinity measurement. | Bai Xue Li Zifu Wang Xuemei He Xi Cheng Shikun Bai Xiaofeng Gao Ruiling | 2017 | International Journal of Agricultural and Biological Engineering2017，10，1： | 1 |
