WYY166 was compared with PA1-10 to examine the taxonomic relationship between the two type strains. The 16S rRNA gene sequence of WYY166 had high similarity (99.9 %) to that of PA1-10. The results of phylogenetic analyses based on 16S rRNA gene sequences indicated that the two strains formed a tight cluster within the genus . 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 as a later heterotypic synonym of .

16S rRNA gene sequence analysis indicated that F21 shared the highest sequence similarity of 100.00% to XAY3209. Phylogenetic analysis based on 16S rRNA gene and whole-genome sequences revealed that F21 formed a cluster with XAY3209, suggesting that there was a close genetic relationship between them.

The present study reports comprehensive phylogenomic and comparative analyses between Dactylosporangium vinaceum NRRL B-16297 and Dactylosporangium matsuzakiense VKM Ac-1321 to clarify their taxonomic relationship. Genomic relatedness analyses between both type strains yielded an average nucleotide identity (ANI) of 97.6%, an average amino acid identity (AAI) of 99.

Three actinobacterial strains, designated as KSW-48, KSWW-56 and SSW1-59, were isolated from seawater, rock-attached living and dried seaweeds collected at Gwakji Beach in Jeju, Republic of Korea. All the isolates showed growth at 15-42 °C and pH 5-10, and tolerated NaCl for growth up to 10%. The 16S rRNA gene-based phylogeny showed that the novel strains were closely related with the type strains of Microbacterium aquimaris and Microbacterium luteum, with the 16S rRNA gene sequence similarity of 99.
