“…Just recently, two species of this genus (Defluviimonas indica [3] and Defluviimonas pyrenivorans [4]) have been transferred to the genus Acidimangrovimonas as Acidimangrovimonas indica and Acidimangrovimonas pyrenivorans [5]. Therefore, at the time of writing, the genus Defluviimonas comprises five species with validly published names, Defluviimonas denitrificans [1], Defluviimonas aestuarii [6], Defluviimonas aquaemixtae [7], Defluviimonas alba [8] and Defluviimonas nitratireducens [9]. Another genus Frigidibacter was introduced by Li and Zhou in 2015 to accommodate only the species Frigidibacter albus [10].…”

A polyphasic taxonomic study was undertaken to clarify the exact position of the type strain cai42T of the species Defluviimonas alba Pan et al. 2015. The results of the 16S rRNA gene sequence analysis indicated that the two sequences from cai42T shared 99.6 and 99.7 % similarity to that of the type strain SP32T of the species Frigidibacter albus and formed a coherent clade in the phylogenetic tree. Whole genomic comparison between cai42T and SP32T yielded a digital DNA–DNA hybridization estimate of 36.3 %, an average nucleotide identity of 88.8 % and an average amino acid identity of 89.8 %, clearly indicating that the two strains should belong to two genospecies of the same genus. The close relationship between the two strains was underpinned by the results of genome-based phylogenetic analysis. Although cai42T and SP32T shared similar physiological and biochemical properties, some striking differences, such as mobility, the temperature range for growth and the polar lipid components, could distinguish them as separate species. Therefore, the comparative phenotypic and genotypic analyses supported the incorporation of Defluviimonas alba into the genus Frigidibacter as Frigidibacter mobilis nom. nov. with the type strain cai42T (=CGMCC 1.12518T=LMG 27406T).

Three Gram-staining-negative, strictly aerobic, non-pigmented, non-motile, rod-shaped bacterial strains, SP32 T (5SLM-1 T), SR68 (5SLM-3) and SP95 (5SLM-2), were isolated from two water samples of a cold-water lake in Xinjiang province, China. Growth was observed at 4-25 6C and pH 6.0-9.0, and optimum growth occurred at 18-20 6C and at pH 7.0-7.5. Phylogenetic analysis of 16S rRNA gene sequences revealed that these isolates belonged to the family Rhodobacteraceae, but formed an evolutionary lineage distinct from other species of this family with validly published names. Strain SP32 T showed the highest 16S rRNA gene sequence similarity (96.7 %) to Rhodobacter veldkampii ATCC 35703 T , and the similarity to members of the genera Defluviimonas, Haematobacter and Pseudorhodobacter was respectively 95.8-96.4, 96.0-96.1 and 95.3-96.1 %. The genomic DNA G+C content of strain SP32 T was 67.6 mol%. The major fatty acids (.5 %) were summed feature 8 (C 18 : 1 v7c/C 18 : 1 v6c) and11-methyl C 18 : 1 v7c. Phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, phosphatidylcholine, one unidentified glycolipid and one unidentified polar lipid were the main polar lipids. Ubiquinone 10 (Q-10) was the sole respiratory quinone. Strain SP32 T did not produce photosynthetic pigments and did not contain the gene pufM, by which it differed from the phototrophic species of the family Rhodobacteraceae. Based on its distinct phenotypic, chemotaxonomic and phylogenetic properties, strain SP32 T represents a novel species in a novel genus within the family Rhodobacteraceae, for which we propose the name Frigidibacter albus gen. nov., sp. nov. The type strain of Frigidibacter albus is strain SP32 T (5SLM-1 T 5CGMCC 1.13995 T 5NBRC 109671 T).

“…The genus Defluviimonas , belonging to the family Rhodobacteraceae , was first described by Foesel et al . (2011) and, at the time of writing, comprises four recognized species, Defluviimonas denitrificans (Foesel et al ., 2011) isolated from the biofilter of a marine aquaculture system, Defluviimonas aestuarii (Math et al , 2013) isolated from a tidal flat of the South Sea in Korea, Defluviimonas indica (Jiang et al , 2014) isolated from a deep-sea hydrothermal vent chimney collected from the South-west Indian Ridge and Defluviimonas aquaemixtae (Jung et al , 2014) isolated from the junction between a freshwater spring and the ocean. Typically, cells of members of this genus are Gram-negative, moderately halophilic, catalase- and oxidase-positive rods, with the major fatty acids being summed feature 8 (C 18 : 1 ω7 c /C 18 : 1 ω6 c ), and the respiratory quinone being Q-10.…”

Two Gram-stain-negative, rod-shaped bacterial strains, cai42T and b45, were isolated from oil-production water taken from Xinjiang Oilfield, China. Optimum growth was observed at 30 6C, at pH 8 and with 1-3 % (w/v) NaCl. According to phylogenetic analyses, the two strains were members of the genus Defluviimonas, with 16S rRNA gene sequence similarities of 95.5"96.3 % with the type strains of species of the genus. The major cellular fatty acids of strains cai42 T and b45 were C 10 : 0 3-OH, C 16 : 0 and summed feature 8 (C 18 : 1 v7c/C 18 : 1 v6c), and the predominant ubiquinone was Q-10, all of these data being typical for the genus Defluviimonas. The polar lipids were phosphatidylethanolamine, phosphatidylglycerol, glycolipid, phosphatidylcholine, two unidentified aminolipids, an unidentified phospholipid and two unidentified lipids. The mean genomic DNA G+C contents of strains cai42 T and b45 were 60.8±1.1 and 60.4±1.0 mol%, respectively. On the basis of phylogenetic, physiological and chemotaxonomic analyses, strains cai42 T and b45 represent a novel species of the genus Defluviimonas, for which the name Defluviimonas alba sp. nov. is proposed. The type strain is cai42 T (5CGMCC
