Abstract

Aliiroseovarius pelagivivens gen. nov., sp. nov., isolated from seawater, and reclassification of three species of the genus Roseovarius as Aliiroseovarius crassostreae comb. nov., Aliiroseovarius halocynthiae comb. nov. and Aliiroseovarius sediminilitoris comb. nov. A variety of coastal seawaters of the South Sea of the Korean Peninsula have been proven to be good sources to isolate novel bacteria (Lee et al., 2011;Jung et al., 2012; Yoon et al., 2013a, b). During isolation of novel bacteria from seawater off Geoje Island in the South Sea of the Korean Peninsula, many novel bacterial strains have been isolated and characterized taxonomically. One of these isolates, designated GYSW-22 T , is described in this study. Comparative 16S rRNA gene sequence analysis showed that this novel strain is phylogenetically most closely related to some species of the genus Roseovarius of the class Alphaproteobacteria. It is known that members of the genus Roseovarius do not form a monophyletic cluster encompassed by the corresponding genus and they may have to be taxonomically re-evaluated (Hameed et al., 2014;Kim et al., 2014; Park et al., 2014a, c, d;Rajasabapathy et al., 2014). Roseovarius marinus has been recently reclassified as 3These authors contributed equally to this work.

“…Although there was a high level of sequence similarity (.95 %) between the novel strain and the strains of species of the genus (Romanenko et al, 2011;Hahnke et al, 2012;Kim et al, 2014). DResult differs from that reported by Park et al (2015).…”

“…S2; Park et al (2015)]. The predominant isoprenoid quinone detected in strain DY6-4 T was ubiquinone-10 (Q-10), which is typical of the vast majority of the class Alphaproteobacteria (Park et al, 2015). The DNA G+C content of strain DY6-4 T was 66.6 mol%, higher than those of the four reference strains (59.0-62.1 %) (Sorokin, 1995;Pukall et al, 1999 (Fig.…”

“…The major polar lipids detected in strain DY6-4 T were phosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine and one unidentified aminolipid, which were all detected in the four reference strains [ Fig. S2; Park et al (2015)].

Roseovarius atlanticus sp. nov., isolated from surface seawater

“…(Biebl et al, 2005); Roseovarius nanhaiticus was isolated from a sandy sediment sample from the South China Sea (Wang et al, 2010); Roseovarius pacificus was isolated from deep-sea sediment of the Western Pacific Ocean (Wang et al, 2009); and Roseovarius lutimaris was isolated from a marine tidal flat (Choi et al, 2013). In addition, three species (Roseovarius crassostreae, Roseovarius halocynthiae and Roseovarius sediminilitoris) of the genus Roseovarius have recently been reclassified into the genus Aliiroseovarius (Park et al, 2015), and the species Roseovarius marinus has been reclassified as 'Pacificibacter marinus' (Park et al, 2014a). The aim of the present work was to determine the exact taxonomic position of strain R12B T by using a polyphasic approach.…”
