Abstract

Abstract

Microbial remediation is one of the widely used remediation techniques in the field of groundwater chromium pollution remediation. Using literature collected from the Web of Science core^® database as the data source， CiteSpace， VOSviewer and Pajek bibliometric software were used to analyze the relevant literature in the field of global groundwater microbial remediation in the past 15 years （2010 to 2024） from three aspects： publication volume， keyword analysis， and policy analysis. The development trend and hotspots of research in this field were systematically sorted out. The results showed that there were a total of 441 research papers in the field of groundwater microbial remediation technology， and the trend of publication has been on the rise in the past 15 years. The development of this field can be divided into three stages： The early research stage （2010 to 2016） mainly focused on the basic treatment methods of chromium pollution； the in-depth exploration stage （2017 to 2019） focused on the intrinsic mechanisms of microbial remediation processes； the expanded research stage （2020 to 2024） shifted its focus to remediation process optimization. Through literature analysis， it is revealed that biological adsorption and biological reduction are the main mechanisms of chromium contaminated microbial remediation. The impact mechanism of four environmental factors， including temperature， pH， initial chromium concentration and reaction time， on microbial remediation was determined through correlation analysis and principal component analysis. Temperature was identified as the key factor affecting remediation efficiency， and the removal efficiency and mechanism of different dominant bacterial strains were summarized， providing reference for the selection of bacterial strains in practical applications. In the future， it is recommended to focus on the synergistic effects of microbial communities， the combination of nanomaterials， and the optimization of environmental conditions to enhance the microbial remediation efficiency of chromium pollution.
