基于文献计量的胞外多糖研究现状和热点分析

Research Status and Hot Spots of Exopolysaccharides Based on Bibliometric Analysis

摘要

摘要: 本文基于科学文献计量学，利用CiteSpace和VOSviewer软件，对2013~2023年Web of Science（WOS）核心合集数据库和中国知网（CNKI）学术期刊数据库中胞外多糖（Exopolysaccharides，EPS）领域4047篇英文文献和1212篇中文文献进行计量统计和可视化分析。从年度发文量、发文作者、高被引文献、发文期刊、发文机构、发文国家、关键词共现和突现等角度，阐述EPS的研究现状和热点。结果表明，EPS领域整体发文量逐年上升，主要集中于Dertli Enes、De Philippis Roberto和Xu Chunping等少数核心作者，作者之间的交流合作有待加强。WOS和CNKI数据库中被引频次最高的文献分别是《Strategies for combating bacterial biofilms: A focus on anti-biofilm agents and their mechanisms of action》和《生物膜形成机理及影响因素探究》。期刊发文量前三的是《International Journal of Biological Macromolecules》《Frontiers in Microbiology》和《Carbohydrate Polymers》。机构发文量前三的是法国科学院（CNRS）、埃及知识库（EKB）、中国科学院。发文国家主要集中于中国、印度和美国，但中国在EPS领域的学术影响力还有待提升。关键词共现分析发现EPS的发酵条件优化、活性功能开发和乳酸菌生产EPS是研究热点。关键词突现分析发现EPS的生物学功能挖掘、生物合成和产业应用是未来研究的主要方向。本文基于文献计量学对EPS领域的研究现状和热点进行了阐述和分析，对未来研究方向提供一定的参考。

Abstract: Based on the bibliometrics of scientific literature, CiteSpace and VOSviewer software were used to investigate exopolysaccharides (EPS) in Web of Science (WOS) core collection database and China National Knowledge Infrastructure (CNKI) database from 2013 to 2023. In the field of EPS, 4047 English literatures and 1212 Chinese literatures were analyzed by quantitative statistics and visualization. The research status and hotspots of EPS were revealed by the perspectives of annual publication numbers, authors, highly cited literatures, publication journals, publication institutions, publication countries, keyword co-occurrences and emergences. The results showed that the overall number of published papers in the field of EPS had increased year by year. Major contributors were Dertli Enes, De Philippis Roberto, Xu Chunping etc., whereas the communication and cooperation among authors needed to be strengthened. The most highly cited literatures in the WOS and CNKI databases were Strategies for combating bacterial biofilms: A focus on anti-biofilm agents and their mechanisms of action and Investigation of Biofilm formation Mechanism and its Influencing Factors, respectively. The top three journals were International Journal of Biological Macromolecules, Frontiers in Microbiology and Carbohydrate Polymers. The top three institutions were Centre National de la Recherche Scientifique (CNRS), Egyptian Knowledge Bank (EKB) and Chinese Academy of Sciences. The publication countries mainly were China, India and the United States, whereas academic impact of China in the field of EPS needed to be improved. Keyword co-occurrence analysis found that the hot spots were optimization of fermentation conditions, developement of EPS function and production EPS by lactic acid bacteria. It revealed that mining of biological function, biosynthesis and industrial application of EPS were the main directions of future research. Based on bibliometrics, this paper expounded and analyzed the research status and hot spots in the field of EPS, providing certain references for future research.
