A novel Gram-reaction-negative, aerobic, pale-orange-pigmented bacterium, designated strain SM1216T, was isolated from Arctic intertidal sand. Cells of strain SM1216T were dimorphic rods with a single polar prostheca or flagellum. The strain grew at 4 − 30 °C (optimum at 25 °C) and with 0.5 − 6 % (w/v) NaCl (optimum with 2 − 3 %). It reduced nitrate to nitrite but did not hydrolyse gelatin, DNA or Tween 80. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain SM1216T was affiliated with the genus Algimonas in the family Hyphomonadaceae, sharing 97.5 and 96.3 % similarity with Algimonas ampicilliniresistens 14A-2-7T and Algimonas porphyrae 0C-2-2T, respectively, the two known species in the genus Algimonas. However, the level of DNA–DNA relatedness between strain SM1216T and the type strain of A. ampicilliniresistens, the nearest phylogenetic neighbour, was 57.9 %. The major cellular fatty acids of strain SM1216T were C18 : 1ω7c and C18 : 1 2-OH. The main polar lipids of strain SM1216T were monoglycosyldiglyceride (MGDG), glucuronopyranosyldiglyceride (GUDG), phosphatidylglycerol (PG) and three unidentified phospholipids (PL1–3). The major respiratory quinone was ubiquinone 10 (Q10). The genomic G+C content of strain SM1216T was 60.6 mol%. On the basis of the evidence from this polyphasic study, strain SM1216T represents a novel species in the genus Algimonas, for which the name Algimonas arctica sp. nov. is proposed. The type strain is SM1216T ( = MCCC 1K00233T = KCTC 32513T). An emended description of the genus Algimonas is also given.

Major Respiratory Quinone

A novel non-sporulating, non-motile, catalase- and oxidase-positive, strictly aerobic, Gram-negative, rod-shaped bacterial strain, designated DCA-1T, was isolated from activated sludge collected from a butachlor wastewater treatment facility. The strain was able to degrade about 85 % of 100 mg butachlor l−1 within 5 days of incubation. Growth occurred in the presence of 0–6 % (w/v) NaCl [optimum, 1 % (w/v) NaCl] and at pH 5.5–9.0 (optimum, pH 7.0) and 15–35 °C (optimum, 25–30 °C). Vesicular internal membrane structures and photoheterotrophic growth were not observed. The major respiratory quinone was ubiquinone 10 (Q-10) and the major cellular fatty acids were C18 : 1ω7c and 11-methyl C18 : 1ω7c. The genomic DNA G+C content of strain DCA-1T was 62.5 mol%. Phylogenetic analysis based on 16S rRNA gene sequence comparison revealed that strain DCA-1T was a member of the family Rhodobacteraceae and was related most closely to the type strain of Catellibacterium aquatile (96.5 % sequence similarity). The combination of phylogenetic analysis, phenotypic characteristics and chemotaxonomic data supports the suggestion that strain DCA-1T represents a novel species of the genus Catellibacterium, for which the name Catellibacterium caeni sp. nov. is proposed. The type strain is DCA-1T ( = CGMCC 1.7745T  = DSM 21823T).

Two non-motile, orange- or yellow-pigmented bacteria, designated strains KYW48T and KYW147T, were isolated from seawater collected from the South Sea, Republic of Korea. Cells of both strains were Gram-reaction-negative, aerobic and catalase- and oxidase-positive. The major fatty acids of strain KYW48T were C18 : 1ω7c (35.3 %), summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1ω7c) (22.7 %), C17 : 1ω6c (19.8 %), C14 : 0 2-OH (7.4 %) and C16 : 0 (5.9 %), and those of strain KYW147T were C18 : 1ω7c (36.0 %), summed feature 3 (18.3 %), C16 : 0 (14.7 %), 11-methyl C18 : 1ω7c (10.7 %), C16 : 0 2-OH (9.1 %) and C18 : 1ω9c (8.0 %). The predominant isoprenoid quinone of both strains was ubiquinone 10 (Q-10). The DNA G+C contents of strains KYW48T and KYW147T were 63.8 and 67.2 mol%, respectively. A phylogenetic tree based on 16S rRNA gene sequences showed that strains KYW48T and KYW147T were grouped with the members of the family Erythrobacteraceae and formed a distinct clade with the members of the genus Altererythrobacter (<95.7 % sequence similarity). On the basis of the evidence presented in this study, the novel species Altererythrobacter namhicola sp. nov. (type strain KYW48T  = KCTC 22736T  = JCM 16345T) and Altererythrobacter aestuarii sp. nov. (type strain KYW147T  = KCTC 22735T  = JCM 16339T) are proposed.
