Research status and trends of mycelial pellets and their application in the field of environment based on bibliometrics

摘要:

菌丝球的发酵培养、形态分析、代谢产物纯化，以及在污水处理和能源回收等领域的应用研究获得了环境和生物领域学者的广泛关注。全面了解菌丝球相关研究的进展和未来的热点趋势。基于Web of Science数据库，筛选出近20年与菌丝球环境应用相关的1 337篇科技文献，采用可视化方法，进行了关键词聚类、关键词时间趋势分析和关键词国家、作者、发文机构共现分析。发现总发文量总体呈上升趋势，共涉及97个学科类别，跨多学科文章较多，也往往具有更高的引用价值，我国在此领域取得的成果显示出明显的优势，并与其他国家保持密切的合作。热门研究关键词一直保持稳定(growth, morphology, fermentation, removal, degradation, mycelial pellets, biological control, fungi, culture, optimization, biodegradation, biosorption)，近年来热度上升和新兴关键词出现了明显的变化。菌丝球在水处理领域的应用研究越来越热，与此相关的关键词(waste water, performance)热度上升；与菌丝球作为生物质载体处理污水(biomass, bacteria)、菌丝球生物合成(biosynthesis)、菌丝球和藻类共生处理污水(Chlorella vulgaris, microalgae)等领域相关的新兴关键词陆续出现并保持热度，表明菌丝球在水处理领域的相关研究逐步划分出更系统的研究方向，成为菌丝球未来的研究热点和机遇。

Abstract:

The fermentation, morphological observation, and metabolite purification of mycelial pellets and the application of mycelial pellets in sewage treatment and energy recovery have gained widespread attention from researchers in the fields of environment and biology. To get a full picture of the research hotspots and trends of mycelial pellets. We screened 1 337 scientific articles related to the application of mycelial pellets that were published in the past 20 years from the Web of Science. The clustering and temporal trends of keywords and the co-occurrence of countries, authors or institutions were visually analyzed. The annual number of published articles was on the rise, involving a total of 97 topics, and interdisciplinary articles were abundant and tended to have higher cited frequency. China’s achievements in this field kept a leading position and China maintained close cooperation with other countries. The hot keywords remained stable (growth, morphology, fermentation, removal, degradation, mycelial pellets, biological control, fungi, culture, optimization, biodegradation, and biosorption), and the uptrending and emerging keywords changed in recent years. The application of mycelial pellets in water treatment had been increasingly studied, with the related keywords (waste water, performance) becoming increasingly frequent. Emerging keywords related to wastewater treatment with mycelial pellets as carriers (biomass, bacteria), synthesis by mycelial pellets (biosynthesis), and water treatment with both mycelial pellets and algae (Chlorella vulgaris, microalgae) remained hot. This result indicates that research on the application of mycelial pellets in water treatment has gradually evolved into more systematic research directions, which will become future research hotspots and opportunities.
