The bacterial strain C3T was isolated from permafrost soil in Beijicun, Mohe County, Heilongjiang province, China. Cells of strain C3T were Gram-stain-negative rods, 0.3–0.4 µm in diameter and 1.0–2.6 µm in length. Strain C3T was strictly aerobic. Growth occurred at 15–37 °C but not at 4 or 42 °C, at pH 5.0–9.0 (optimum pH 6.0–7.0) and in the presence of 0–8 g NaCl l−1 (optimum 0–1 g l−1). The analysis of 16S rRNA gene sequences indicated that strain C3T was phylogenetically related to members of the genus Undibacterium , with similarities ranging from 94.7 to 96.5 %. Strain C3T contained ubiquinone 8 as the major respiratory quinone. The major cellular fatty acids were summed feature 3 (C16 : 1ω7c/C16 : 1ω6c), C17 : 0 cyclo, straight-chain C16 : 0, C12 : 0 and C10 : 0, unsaturated C18 : 1ω7c and hydroxylated fatty acids C10 : 0 3-OH and C12 : 0 2-OH. The polar lipids were mainly phosphatidylethanolamine, diphosphatidylglycerol and phosphatidylglycerol. The polyamines were putrescine and 2-hydroxyputrescine. The DNA G+C content was 57.4 mol% (determined from Tm ). Based on these results, it is concluded that strain C3T represents a novel species of the genus Undibacterium , for which the name Undibacterium terreum sp. nov. is proposed, with C3T ( = CGMCC 1.10998T = NBRC 108789T) representing the type strain.

A Gram-stain-negative, orange-pigmented and strictly aerobic bacterium, designated strain MJ115T, was isolated from seawater in Pohang, South Korea. Cells were non-motile rods and showed positive reactions for catalase and oxidase tests. Growth of strain MJ115T was observed at 4–35 °C (optimum, 30 °C), pH 6.0–7.0 (optimum, pH 6.5) and in the presence of 0–8.0 % (w/v) NaCl (optimum, 2.0%). Strain MJ115T contained iso-C15 : 0, anteiso-C15 : 0, anteiso-C17 : 1  ω9c, C17 : 0 2-OH, iso-C16 : 0 3-OH, iso-C17 : 0 3-OH and summed feature 3 (C16 : 1  ω7c and/or C16 : 1  ω6c) as major cellular fatty acids and menaquinone-6 as the major respiratory quinone. Phosphatidylethanolamine, two unidentified aminolipids and four unidentified lipids were detected as major polar lipids. The G+C content of the genomic DNA was 40.7 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain MJ115T formed a phyletic lineage with Nonlabens marinus S1-08T, Nonlabens agnitus JC2678T and Nonlabens antarcticus AKS 622T within the genus Nonlabens . Strain MJ115T was also most closely related to N. marinus S1-08T, N. agnitus JC2678T and N. antarcticus AKS 622T with 96.5, 96.4 and 96.0 % 16S rRNA sequence similarities, respectively. Here it is proposed that strain MJ115T represents a new species of the genus Nonlabens , for which the name Nonlabens ponticola sp. nov. is proposed. The type strain is MJ115T (=KCTC 72237T=NBRC 113963T). In addition, the comparison of the whole genome sequences and phenotypic features suggested that Nonlabens tegetincola and Nonlabens sediminis belong to the same species. Therefore, it is proposed that N. sediminis is reclassified as a later heterotypic synonym of N. tegetincola .

A Gram-stain-negative, rod-shaped, strictly aerobic, flagellated and non-spore-forming marine bacterium designated strain CC-AMO-30BT was isolated from coastal surface seawater, Taiwan. Strain CC-AMO-30BT synthesized astaxanthin [40 µg (g dry weight)−1] and formed reddish-orange-coloured colonies on marine agar (Difco 2216). The strain showed highest pairwise 16S rRNA gene sequence similarity to Sphingomicrobium lutaoense CC-TBT-3T (96.4 %) followed by other members of the family Sphingomonadaceae (<94 %) and established a discrete phyletic lineage associated with the former. The polar lipid profile constituted a remarkable number of unidentified glycolipids (GL1–8), in addition to diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, sphingoglycolipid and two unidentified lipids (L1–2). The major fatty acids (>5 % of total fatty acids) were C18 : 1ω7c/C18 : 1ω6c (summed feature 8), C16 : 1ω7c/C16 : 1ω6c (summed feature 3), C18 : 1 2-OH, methyl C18 : 1ω7c, C17 : 1ω6c and C16 : 0. DNA G+C content was 70.6 %; major respiratory quinone was ubiquinone Q-10; predominant polyamine was the triamine sym-homospermidine.
