A polyphasic taxonomic study was undertaken to clarify the exact position of type strain DY6-4T of Xuhuaishuia manganoxidans. A combination of physiological properties of X. manganoxidans DY6-4T was consistent with those of type strain 22DY15T of Brevirhabdus pacifica. The 16S rRNA gene sequence analyses indicated that X. manganoxidans DY6-4T and B. pacifica 22DY15T shared 100 % similarity and formed a monophyletic group. The close relationship between the two strains was underpinned by the results of chemotaxonomic characteristics, including the fatty acids, quinone and polar lipids. The digital DNA-DNA hybridization and average nucleotide identity values between the two strains were 99.90 and 99.98 %, respectively. Based on these results, we propose that Xuhuaishuia manganoxidans is a later heterotypic synonym of Brevirhabdus pacifica.
