Abstract

A polyphasic taxonomic study was undertaken to clarify the exact position of type strain DY6-4 of Xuhuaishuia manganoxidans . A combination of physiological properties of X. manganoxidans DY6-4 was consistent with those of type strain 22DY15 of Brevirhabdus pacifica . The 16S rRNA gene sequence analyses indicated that X. manganoxidans DY6-4 and B. pacifica 22DY15 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 .
