Abstract：
Antibiotic residues in aquatic environments pose a potential hazard, and microbes, which play important roles in aquatic ecosystems, are vulnerable to the impacts of antibiotics. This study aimed to analyze the research progress, trends, and hot topics of the impact of antibiotics on microbial community and biodegradation mechanism using bibliometric analysis. An in-depth analysis of the publication characteristics of 6143 articles published between 1990 and 2021 revealed that the number of articles published increased exponentially. The research sites have been mainly concentrated in the Yamuna River, Pearl River, Lake Taihu, Lake Michigan, Danjiangkou Reservoir, etc., illustrating that research around the world is not even. Antibiotics could change the diversity, structure, and ecological functions of bacterial communities, stimulate a widespread abundance of antibiotic-resistant bacteria and antibiotic-resistant genes, and increase the diversity of eukaryotes, thus triggering the shift of food web structure to predatory and pathogenic. Latent Dirichlet allocation theme model analysis showed three clusters, and the research hotspots mainly included the effect of antibiotics on the denitrification process, microplastics combined with antibiotics, and methods for removing antibiotics. Furthermore, the mechanisms of microbe-mediated antibiotic degradation were unraveled, and importantly, we provided bottlenecks and future research perspectives on antibiotics and microbial diversity research.
摘要：
水生环境中的抗生素残留构成潜在危害，和微生物，它们在水生生态系统中起着重要的作用，容易受到抗生素的影响。本研究旨在分析研究进展,趋势,用文献计量学方法分析抗生素对微生物群落的影响和生物降解机理。对1990年至2021年间发表的6143篇文章的发表特征进行深入分析后发现，发表的文章数量呈指数级增长。研究地点主要集中在亚穆纳河,珠江,太湖,密歇根湖,丹江口水库,等。,说明世界各地的研究都没有。抗生素可以改变多样性，结构,和细菌群落的生态功能，刺激大量的抗生素抗性细菌和抗生素抗性基因，增加真核生物的多样性，从而引发了食物网结构向掠夺性和致病性的转变。潜在的狄利克雷分配主题模型分析显示了三个集群，研究热点主要包括抗生素对反硝化过程的影响,微塑料与抗生素结合，以及去除抗生素的方法。此外，微生物介导抗生素降解的机制被揭开，而且重要的是,我们提供了抗生素和微生物多样性研究的瓶颈和未来研究前景。
