Visual analysis of research on microbial extracellular polymeric substances based on bibliometrics

【背景】胞外聚合物是微生物分泌的高分子聚合物,在环境治理、材料科学、生物医学等领域具有重要的应用价值。【目的】探讨胞外聚合物研究现状、研究热点和发展趋势。【方法】采用文献计量学方法,基于Web of Science核心合集数据库,检索近10年胞外聚合物相关文献,利用VOSviewer软件进行统计分析。【结果】胞外聚合物研究发文量呈上升趋势,中国发文量居首,但质量有待提高;研究热点主要集中在环境治理、生物制造和生物矿化等领域;微塑料降解是当前研究热点之一。【结论】本研究为深入了解胞外聚合物研究现状以及把握发展趋势提供了依据。

[Background]Extracellular polymeric substances(EPS),polymers secreted by microorganisms,have been applied in environmental management,material science,and biomedicine.[Objective]To discuss the research status,hotspots,and trends of EPS.[Methods]We retrieved the publications related to EPS in the last 10 years from the Web of Science Core Collection and employed VOSviewer to perform the statistical analysis.[Results]The number of publications about EPS was on the rise.China had the largest number of publications,the quality of which,however,remained to be improved.The research on EPS mainly involved environmental governance,biomanufacturing,and biomineralization.The degradation of microplastics is one of the hotspots.[Conclusion]This study provides a basis for understanding the research status and trends of EPS.
