先前关于微生物（过）氯酸盐还原的普遍性和多样性的研究导致分离出20种新的异化（过）氯酸盐还原细菌菌株。系统发育分析表明，所有的分离株的成员变形菌的代表在α，β和γ-亚类。大多数新的分离物位于β-亚类，彼此之间以及与光养红环藻属物种密切相关。在这里，深入分析这些生物，形成两个不同的单系类群内的Rhodocyclos组合。两个新的属，Dechloromonas和Dechlorosoma，提出了这些β亚类谱系，代表了环境中的主要（全）氯酸盐还原菌。这些新属的模式种和菌株分别为Dechloromonasagitata菌株CKBT和Dechlorosomassuillum菌株PST。
Previous studies on the ubiquity and diversity of microbial (per)chlorate reduction resulted in the isolation of 20 new strains of dissimilatory (per)chlorate-reducing bacteria. Phylogenetic analysis revealed that all of the isolates were members of the Proteobacteria with representatives in the alpha-, beta- and gamma -subclasses. The majority of the new isolates were located in the beta -subclass and were closely related to each other and to the phototrophic Rhodocyclus species. Here an in-depth analysis of these organisms which form two distinct monophyletic groups within the Rhodocyclus assemblage is presented. Two new genera, Dechloromonas and Dechlorosoma, are proposed for these beta -subclass lineages which represent the predominant (per)chlorate-reducing bacteria in the environment. The type species and strains for these new genera are Dechloromonas agitata strain CKBT and Dechlorosoma suillum strain PST, respectively.
