“…The polar lipid pattern of strain B14 T can be distinguished from that of other Roseobacter species. To mention just a few differences, in R. litoralis Och 149 T phosphatidylcholine was not detected [4], which, however, was one of the main polar lipids in all other Roseobacter type strains with validly published names [4–6] and in strain B14 T . On the other hand, the polar lipid diphosphatidylglycerol was present in minor amounts in all Roseobacter species [4–6] but was not detected in strain B14 T (Fig.…”

“…The genus Roseobacter was proposed in 1991 by Shiba with the description of Roseobacter litoralis and Roseobacter denitrificans [1], and recently assigned to the family Roseobacteraceae [2]. According to the List of Prokaryotic Names with Standing in Nomenclature (https://lpsn.dsmz.de/) [3], the genus currently comprises three additional species with validly published names, Roseobacter ponti [4], Roseobacter cerasinus [5], and Roseobacter insulae [6]. All five species of the genus Roseobacter exhibit a marine lifestyle, whereas R. litoralis and R. denitrificans were isolated from high tidal seaweeds [1], R. ponti and R. cerasinus from seawater, and R. insulae from tidal flat sediment.…”

A Gram-negative, aerobic, pink-pigmented, and bacteriochlorophyll a-containing bacterial strain, designated B14T, was isolated from the macroalga Fucus spiralis sampled from the southern North Sea, Germany. Based on 16S rRNA gene sequences, species of the genera Roseobacter and Sulfitobacter were most closely related to strain B14T with sequence identities ranging from 98.15 % (Roseobacter denitrificans Och 114T) to 99.11 % (Roseobacter litoralis Och 149T), whereas Sulfitobacter mediterraneus CH-B427T exhibited 98.52 % sequence identity. Digital DNA–DNA hybridization and average nucleotide identity values between the genome of the novel strain and that of closely related Roseobacter and Sulfitobacter type strains were <20 % and <77 %, respectively. The novel strain contained ubiquinone-10 as the only respiratory quinone and C18 : 1 ω7c, C16 : 0, C18 : 0, C12 : 1 ω7c, C18 : 2 ω7,13c, and C10 : 0 3-OH as the major cellular fatty acids. The predominant polar lipids of strain B14T were phosphatidylcholine, phosphatidylethanolamine, and phosphatidylglycerol. The genome of strain B14T comprises a chromosome with a size of 4.5 Mbp, one chromid, and four plasmids. The genome contains the complete gene cluster for aerobic anoxygenic photosynthesis required for a photoheterotrophic lifestyle. The results of this study indicate that strain B14T (=DSM 116946T=LMG 33352T) represents a novel species of the genus Roseobacter for which the name Roseobacter fucihabitans sp. nov. is proposed.

Pseu.do.o.ce.a.ni'co.la. Gr. masc./fem. adj. pseudês , false; N.L. masc. n. Oceanicola , a bacterial genus; N.L. masc. n. Pseudooceanicola , like Oceanicola , referring to the close relationship to the genus Oceanicola . Pseudomonadota / Alphaproteobacteria / Rhodobacterales / Roseobacteraceae/ Pseudooceanicola The genus Pseudooceanicola , classified within the family Roseobacteraceae , order Rhodobacterales , class Alphaproteobacteria , and in the phylum Pseudomonadota , currently includes 11 species with validly published names. Cells are Gram‐stain‐negative, aerobic or facultatively anaerobic, non‐motile, polymorphic‐shaped including short rods, ovoid or irregular elongated rod. Cells reproduce by normal cell division and occur singly or in shapeless aggregates. The Pseudooceanicola strains are slightly halophlic or haloduric, mostly grow well in the salinity ranges of 0–17.5% (w/v) NaCl, with the optimum of 0.5–8.0% (w/v) NaCl. Growth at pH ranges from 4.0 to 10.0, with optimum growth at approx. pH 6.0–8.5. The Pseudooceanicola species are mesophilic bacteria. The temperature range of growth is 4–45°C, with optimum growth at 20–37°C. The colony color is cream, white, or yellowish. Some species synthesize poly‐β‐hydroxybutyrate (PHB) granules. Most species are also capable of growth on some multicarbon compounds, such as l ‐arabinose, d ‐glucose, d ‐maltose, d ‐mannitol, d ‐mannose, and N ‐acetyl‐glucosamine. The major isoprenoid quinone is ubiquinone‐10 (Q‐10). The major fatty acid includes octadecenoic acid summed feature 8 (C 18:1 ω7 c and/or C 18:1 ω6 c ) and C 16:0 . Known habitats are mainly marine environments, such as seawater, sediment, macroalgae, and epidermis of a marine invertebrate, and surface‐sterilized bark. DNA G + C content (mol%) : 64.1–67.9 (by genome). Type species : Pseudooceanicola atlanticus Lai et al. 2015, VL164.
