Abstract
The genus Roseivirga currently includes five species: Roseivirga ehrenbergii, R. echinicomitans, R. spongicola, R. marina and R. maritima. Marinicola seohaensis SW-152T was renamed as Roseivirga seohaensis SW-152T and then reclassified again as a later heterotypic synonym of R. ehrenbergii KMM 6017T. In this study, based on average nucleotide identity and digital DNA– DNA hybridization values obtained from in silico methods, together with fatty acid analyses and biochemical tests, we propose to reclassify R. ehrenbergii SW-152 as Roseivirga seohaensis comb. nov. (type strain SW-152T=KCTC 1231T=JCM 12600T). In this work, a Gram-negative, rod-shaped, aerobic and pink-pigmented strain designated as D-25T was isolated from seawater (Desaru Beach, Johor, Malaysia). The 16S rRNA gene analysis revealed that strain D-25T was related to the genus Roseivirga. Strain D-25T was found most closely related to R. seohaensis SW-152T based on average nucleotide identity and digital DNA–DNA hybridization values, phenotypic and chemotaxonomic analyses, indicating that these strains belong to the same species. Thus, it is proposed to split the species R.oseivirga seohaensis into two novel subspecies, Roseivirga seohaensis subsp. seohaensis subsp. nov. (type strain SW-152T=KCTC 12312T=JCM 12600T) and Roseivirga seohaensis subsp. aquiponti subsp. nov. (type strain D-25T=KCTC 42709T=DSM 101709T) and to emend the description of the genus Roseivirga.
