Abstract
Nonomuraea nitratireducens WYY166T was compared with Nonomuraea phyllanthi PA1-10T to examine the taxonomic relationship between the two type strains. The 16S rRNA gene sequence of N. nitratireducens WYY166T had high similarity (99.9 %) to that of N. phyllanthi PA1-10T. The results of phylogenetic analyses based on 16S rRNA gene sequences indicated that the two strains formed a tight cluster within the genus Nonomuraea . Draft genomic comparison between the two strains revealed an average nucleotide identity of 99.3 % and a digital DNA–DNA hybridization estimate of 94.4±1.8 %, strongly indicating that the two strains represented a single species. In addition, neither strain displayed any striking difference in metabolic, physiological or chemotaxonomic features. Therefore, we propose Nonomuraea nitratireducens as a later heterotypic synonym of Nonomuraea phyllanthi .
