Microorganisms play a vital role in biological wastewater treatment by converting organic and toxic materials into harmless substances. Understanding microbial communities' structure, taxonomy, phylogeny, and metabolic activities is essential to improve these processes. Molecular microbial ecology employs molecular techniques to study community profiles and phylogenetic information since culture-dependent approaches have limitations in providing a comprehensive understanding of microbial diversity in a system. Genomic advancements such as DNA hybridization, microarray analysis, sequencing, and reverse sample genome probing have enabled the detailed characterization of microbial communities in wastewater treatment facilities. This mini-review summarizes the current state of knowledge on the diversity of microorganisms in wastewater treatment plants, emphasizing critical microbial processes such as nitrogen and phosphorus removal.
微生物在生物废水处理中起着至关重要的作用，它们将有机和有毒物质转化为无害物质。了解微生物群落的结构、分类、系统发育和代谢活动对于改进这些过程至关重要。分子微生物生态学利用分子技术来研究群落谱和系统发育信息，因为基于培养的方法在提供对系统中微生物多样性的全面了解方面存在局限性。基因组学的进步，如 DNA 杂交、微阵列分析、测序和反向样品基因组探测，使我们能够详细描述废水处理设施中的微生物群落。本综述总结了目前关于废水处理厂中微生物多样性的知识状况，强调了氮磷去除等关键微生物过程。
