Microbial remediation technology has received much attention as a green, ecological, and inexpensive technology, and there is great potential for the application of microbial remediation technology for heavy metals (HMs) contaminated soil alone and in conjunction with other technologies in environmental remediation. To gain an in-depth understanding of the latest research progress, research hotspots, and development trends on microbial remediation of HMs-contaminated soil, and to objectively reflect the scientific contributions and impacts of relevant countries/regions, institutions, and individuals of this field, in this manuscript, ISI Web of Knowledge's Web of Science™ core collection database, data visualization, and analysis software Bibliometrix, VOSviewer, and HistCite Pro were used to collect and analyze the relevant literature from 2000 to 2022, and 1409 publications were subjected to scientometric analyses. It involved 327 journals, 5150 authors, 75 countries/regions, and 2740 keywords. The current progress and hotspots on microbial remediation of HMs-contaminated soil since the twenty-first century were analyzed in terms of the top 10 most productive countries (regions), high-yielding authors, source journals, important research institutions, and hotspots of research directions. Over the past 22 years, China, India, and the USA have been the countries with the most articles. The institution and author with the most publications are the Chinese Acad Sci and Zhu YG, respectively. Journal of Hazardous Materials is the most productive journal. The keywords showed 6 co-occurrence clusters. These findings revealed the research hotspots, knowledge gaps, and future exploration trends related to microbial remediation of HMs-contaminated soil.
微生物修复技术作为一种绿色、生态、廉价的技术受到了广泛关注，其在重金属（HM）污染土壤的单独应用以及与其他技术在环境修复中的联合应用具有巨大的潜力。为了深入了解 HM 污染土壤微生物修复的最新研究进展、研究热点和发展趋势，并客观反映该领域相关国家/地区、机构和个人的科学贡献和影响力，本研究采用 ISI Web of Knowledge 的 Web of ScienceTM 核心合集数据库、数据可视化和分析软件 Bibliometrix、VOSviewer 和 HistCite Pro，收集和分析了 2000 年至 2022 年的相关文献，对 1409 篇文献进行了科学计量分析。涉及 327 种期刊、5150 位作者、75 个国家/地区和 2740 个关键词。本研究从发文量最多的 10 个国家（地区）、高产作者、来源期刊、重要研究机构和研究方向热点等方面分析了 21 世纪以来 HM 污染土壤微生物修复的研究现状和热点。在过去的 22 年中，中国、印度和美国一直是发文量最多的国家。发文量最多的机构和作者分别是中国科学院和朱永官。高产期刊是《Journal of Hazardous Materials》。关键词显示出 6 个共现聚类。这些发现揭示了 HM 污染土壤微生物修复的研究热点、知识空白和未来探索趋势。
