摘　　要：黏细菌是一类捕食性革兰氏阴性菌,广泛分布在土壤、海洋和淡水等生境中,是多类环境的优势类群。根据16S rRNA基因序列,黏细菌被归属于变形菌门的δ分支黏细菌目(Myxococcales)。新近根据120个保守性的单拷贝标识基因和16S rRNA基因序列,对变形菌门的系统分类学研究将黏细菌类群单列为黏细菌门(Myxococcota)。本文介绍了黏细菌资源的特性,并围绕从目到门的分类地位变迁,系统简述了黏细菌分类学研究的历史演变,对黏细菌资源的应用和发展进行了展望。Myxobacteria are predatory Gram-negative bacteria ubiquitous and often predominant in soil,ocean,and freshwater environments.According to the 16S rRNA gene sequences,myxobacteria were classified as an order Myxococcales affiliated to the classδ-Proteobacteria.The recent phylogenetic studies based on 120 conserved single-copy marker genes and the 16S rRNA gene sequences have upgraded Myxococcales to the phylum Myxococcota.This review briefly summarizes the characteristics of myxobacteria and the history of the phylogenetic research and then makes a perspective on the future studies and applications of myxobacterial resources.
