The taxonomic position of a misclassified strain, Zoogloea remigera IAM 12670T (= ATCC 25925T = P. R. Dugan 115T), was reevaluated. A phylogenetic analysis based on 16S ribosomal rDNA sequences revealed that this organism was located in the beta subclass of the class Proteobacteria with members of the genus Telluria as its closest relatives. On the basis of phenotypic and phylogenetic information, we propose that this organism should be reclassified in a new taxon with the name Duganella zoogloeoides gen. nov., sp. nov.
