Abstract
A yellow, Gram-stain-negative, aerobic, and rod-shaped strain, designated as C18T, was isolated from seawater in the tidal region of Taizhou. Growth of strain C18T occurs at 20-45 °C, at pH 5.5-8.0 and with 1.0-8.0% (w/v) NaCl. The 16S rRNA gene sequence analysis showed that strain C18T shared sequence identities with the genera Erythrobacter (< 98.4%), Qipengyuania (< 98.0%), Altererythrobacter (< 96.4%), Parerythrobacter (< 96.2%), Aurantiacibacter (< 96.2%), Tsuneonella (< 96.0%), Pelagerythrobacter (< 96.0%), Alteriqipengyuania (< 95.9%), and Parapontixanthobacter (< 95.7%) type strains. While the phylogenomic tree based on single-copy orthologous clusters revealed that strain C18T was stably clustered into the genus Parerythrobacter. Average nucleotide identity and digital DNA-DNA hybridization values of strain C18T and Parerythrobacter type strains were 73.5-75.2% and 18.5-19.4%, respectively, which were lower than the species delineation thresholds. The sole respiratory quinones were identified as ubiquinone-10. The major fatty acids (> 10%) were C17:1ω6c and summed feature 8 (C18:1ω7c and/or C18:1ω6c). Polar lipids included diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, sphingoglycolipid, an unidentified phospholipid, and an unidentified aminophospholipid. Based on the genetic, chemotaxonomic and phenotypic results, strain C18T is concluded to represent a novel species in the genus Parerythrobacter, for which the name Parerythrobacter aestuarii sp. nov. is proposed. The type strain is C18T (= KCTC 82594T = MCCC 1K05109T).

Abstract
A novel bacterium, designated as strain RS5-5T, was isolated from lake water in northwestern China. Cells of the isolate were observed to be rod shaped and Gram stain negative. Its growth occurred at 4-37 ℃, pH 6.5-9.0 and in the presence of 0-5% (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain RS5-5T was most closely related to Qipengyuania sediminis GDMCC 1.2497T (97.5%), followed by Erythrobacter dokdonensis DSW-74T (97.3%) and Qipengyuania algicida GDMCC 1.2535T (97.0%). Phylogenomic analysis revealed that strain RS5-5T formed a distinct branch with the genus Parerythrobacter. The sole quinone was ubiquinone-10, and the major fatty acids (≥ 10%) were unsaturated fatty acids including C17:1 ω6c, summed feature 3 (C16:1 ω7c/C16:1 ω6c) and summed feature 8 (C18:1 ω7c/C18:1 ω6c). The polar lipids were phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, one unidentified sphingoglycolipid, three unidentified glycolipids, one unidentified aminoglycolipid, one unidentified aminolipid, two unidentified phospholipids and four unidentified polar lipids. Chemotaxonomic characteristics of strain RS5-5T were coincident with those of the genus Parerythrobacter members. The average nucleotide identity, average amino acid identity and digital DNA-DNA hybridization values between strain RS5-5T and two Parerythrobacter reference strains were in the ranges of 73.2-77.7%, 69.0-78.0% and 18.9-20.4%, respectively. The genomic DNA G + C content of strain RS5-5T was 64.1%. The results of phenotypic, phylogenetic and genomic analyses suggested that strain RS5-5T represents a novel species in the genus Parerythrobacter, for which the name Parerythrobacter lacustris sp. nov. is proposed. The type strain is RS5-5T (= GDMCC 1.3163T = KCTC 92277T).

Abstract
A study based on a polyphasic taxonomic approach was carried out to identify and classify a novel marine alphaproteobacterium, designated as KMU-140T, isolated from coastal seawater collected at Jeju Island, Republic of Korea. Cells of strain KMU-140T were spherical, Gram-stain-negative, reddish-orange colored, strictly aerobic, catalase- and oxidase-positive, non-motile, and chemoorganoheterotrophic. The novel isolate was able to grow at NaCl concentrations of 0-5%, pH 6.0-9.5, and 10-45 °C. A phylogenetic analysis based on the 16S rRNA gene sequence showed that strain KMU-140T belongs to the family Erythrobacteraceae and was most closely related to Erythrobacter longus OCh101T (98.7%). Strain KMU-140T contained ubiquinone-10 (Q-10) as the only respiratory quinone and C18:1 ω7c, iso-C18:0, and C16:0 as the main (> 10%) cellular fatty acids. Strain KMU-140T produced carotenoid compounds that rendered the cell biomass a reddish-orange color. The assembled draft genome size of strain KMU-140T was 3.04 Mbp with G + C content of 60.6 mol%. The average nucleotide identity (ANI), digital DNA-DNA hybridization (dDDH), and average amino acid identity (AAI) values of KMU-140T and the species of the genus Erythrobacter were found to be 76.6-78.4%, 14.0-18.7%, and 69.6-77.8%, respectively. Phosphatidylethanolamine, phosphatidylglycerol, an unidentified phospholipid, and two unidentified lipids were identified as major polar lipids. On the basis of the polyphasic taxonomic features presented, the strain is considered to represent a novel species of the genus Erythrobacter for which the name Erythrobacter rubeus sp. nov. is proposed. The type strain of E. rubeus sp. nov. is KMU-140T (= KCCM 90479T = NBRC 115159T).

Abstract
The family Erythrobacteraceae, belonging to the order Sphingomonadales, class Alphaproteobacteria, is globally distributed in various environments. Currently, this family consist of seven genera: Altererythrobacter, Croceibacterium, Croceicoccus, Erythrobacter, Erythromicrobium, Porphyrobacter and Qipengyuania. As more species are identified, the taxonomic status of the family Erythrobacteraceae should be revised at the genomic level because of its polyphyletic nature evident from 16S rRNA gene sequence analysis. Phylogenomic reconstruction based on 288 single-copy orthologous clusters led to the identification of three separate clades. Pairwise comparisons of average nucleotide identity, average amino acid identity (AAI), percentage of conserved protein and evolutionary distance indicated that AAI and evolutionary distance had the highest correlation. Thresholds for genera boundaries were proposed as 70 % and 0.4 for AAI and evolutionary distance, respectively. Based on the phylo-genomic and genomic similarity analysis, the three clades were classified into 16 genera, including 11 novel ones, for which the names Alteraurantiacibacter, Altericroceibacterium, Alteriqipengyuania, Alteripontixanthobacter, Aurantiacibacter, Paraurantiacibacter, Parerythrobacter, Parapontixanthobacter, Pelagerythrobacter, Tsuneonella and Pontixanthobacter are proposed. We reclassified all species of Erythromicrobium and Porphyrobacter as species of Erythrobacter. This study is the first genomic-based study of the family Erythrobacteraceae, and will contribute to further insights into the evolution of this family.

Abstract
Erythrobacter flavus strain KJ5 (formerly called Erythrobacter sp. strain KJ5) is a yellowish marine bacterium that was isolated from a hard coral Acropora nasuta in the Karimunjawa Islands, Indonesia. The complete genome sequence of the bacterium has been reported recently. In this study, we examined the carotenoid composition of this bacterium using high-performance liquid chromatography coupled with ESI-MS/MS. We found that the bacterium produced sulfur-containing carotenoids, i.e., caloxanthin sulfate and nostoxanthin sulfate, as the most abundant carotenoids. A new carotenoid zeaxanthin sulfate was detected based on its ESI-MS/MS spectrum. The unique presence of sulfated carotenoids found among the currently known species of the Erythrobacter genus were discussed.

Abstract
A rod-shaped, Gram-staining-negative and orange-pigmented bacterium, designated strain HME9302T, was isolated from seawater of the Yellow Sea in the Republic of Korea. The phylogenetic tree based on 16S rRNA gene sequences showed that strain HME9302T formed a lineage within the genus Altererythrobacter, and was most closely related to Altererythrobacter aurantiacus O30T with 96.7 % sequence similarity. The major fatty acids were summed feature 8 (comprising C18 : 1ω7c and/or C18 : 1ω6c), summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c) and C16 : 0. The major respiratory quinone was ubiquinone-10. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, sphingoglycolipid and four unidentified lipids. The DNA G+C content was 60.8 mol%. On the basis of the evidence presented in this study, strain HME9302T represents a novel species of the genus Altererythrobacter, for which the name Altererythrobacter maritimus sp. nov. is proposed with the type strain HME9302T (=KCTC 32463T=KACC 17617T=CECT 8417T).

Abstract
A Gram-stain-negative, motile, rod-shaped, orange-pigmented bacterium able to degrade polycyclic aromatic hydrocarbons was isolated from deep-sea sediment of the Atlantic Ocean and subjected to a polyphasic taxonomic study. The strain, designated s21-N3T, could grow at 4–37 °C (optimum 28 °C), at pH 5–10 (optimum pH 7–8) and with 1–7 % (w/v) NaCl (optimum 2–3 %). Strain s21-N3T was positive for nitrate reduction, denitrification, aesculin hydrolysis, oxidase and catalase, but negative for indole production and urease. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain s21-N3T formed a distinct branch within the genus Erythrobacter, sharing high similarities with three closely related strains, Erythrobacter marinus HWDM-33T (98.67 %), ‘Erythrobacter luteus’ KA37 (97.80 %) and Erythrobacter gangjinensis K7-2T (97.59 %). The similarities between strain s21-N3T and other type strains of recognized species within the genus Erythrobacter ranged from 95.00 to 96.47 %. The digital DNA–DNA hybridization values and average nucleotide identity (ANI) values between strain s21-N3T and the three closely related strains Erythrobacter marinus HWDM-33T, ‘Erythrobacter luteus’ KA37 and Erythrobacter gangjinensis K7-2T were 18.60, 18.00 and 18.50 % and 74.24, 72.49 and 72.54 %, respectively. The principal fatty acids were summed feature 8 (C18 : 1ω7c/ω6c) and summed feature 3 (C16 : 1ω7c/ω6c). The respiratory lipoquinone was identified as Q-10. The major polar lipids comprised sphingoglycolipid, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine and diphosphatidylglycerol. The G+C content of the chromosomal DNA was determined to be 58.18 mol%. The combined genotypic and phenotypic distinctiveness demonstrated that strain s21-N3T represents a novel species of the genus Erythrobacter, for which the name Erythrobacter atlanticus sp. nov. is proposed, with the type strain s21-N3T ( = MCCC 1A00519T = KCTC 42697T).

Abstract
A Gram-staining-negative, orange-pigmented, aerobic bacterial strain, designated KA37T, was isolated from a mangrove sediment sample collected from Yunxiao mangrove National Nature Reserve, Fujian Province, China. Growth was observed at 4-37 °C, 0-3% (w/v) NaCl and pH 5-10. Mg2+ ions were required for growth. Phylogenetic analysis based on 16S rRNA gene sequencing revealed that the isolate was a member of the genus Erythrobacter, which belongs to the family Erythrobacteraceae. Strain KA37T was most closely related to Erythrobacter gangjinensis KCTC 22330T (96.9% sequence similarity), followed by Erythrobacter marinus KCTC 23554T (96.8%); similarity to other members of the genus was below 96.6%. The major fatty acids were C17 : 1ω6c, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c). Strain KA37T did not produce bacteriochlorophyll a. The predominant respiratory quinone was ubiquinone 10 (Q-10). The polar lipids of strain KA37T were sphingoglycolipid, phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, five unknown lipids and one unidentified phospholipid. According to its morphology, physiology, fatty acid composition and 16S rRNA sequence, the novel strain most appropriately belongs to the genus Erythrobacter, but can be distinguished readily from species of the genus Erythrobacter with validly published names. The name Erythrobacter luteus sp. nov. is proposed, with strain KA37T ( = MCCC 1F01227T = KCTC 42179T) as the type strain.

Abstract
A Gram-stain-negative, non-motile, coccoid- or oval-shaped bacterial strain, designated S-5T, belonging to the class
Alphaproteobacteria
, was isolated from a tidal flat sediment of the Yellow Sea, Korea and was subjected to a polyphasic taxonomic study. Strain S-5T grew optimally at pH 7.0–8.0, at 30 °C and in the presence of 2–3 % (w/v) NaCl. Neighbour-joining analysis based on 16S rRNA gene sequences showed that strain S-5T fell within the clade comprising the species of the genus
Erythrobacter
, clustering with the type strains of
Erythrobacter pelagi
,
Erythrobacter citreus
and
Erythrobacter seohaensis
with which it exhibited the highest 16S rRNA gene sequence similarity (96.0–96.7 %). The DNA G+C content was 66.0 mol%. Strain S-5T contained Q-10 as the predominant ubiquinone and summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c) and C17 : 1ω6c as the major fatty acids. The major polar lipids were sphingoglycolipid, phosphatidylcholine, phosphatidylglycerol, an unidentified glycolipid and two unidentified lipids. Differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, demonstrated that strain S-5T is distinguishable from other species of the genus
Erythrobacter
. On the basis of the data presented, strain S-5T is considered to represent a novel species of the genus
Erythrobacter
, for which the name Erythrobacter
lutimaris sp. nov. is proposed. The type strain is S-5T ( = KCTC 42109T = CECT 8624T).

Abstract
A Gram-stain negative, yellow-pigmented, motile, pleomorphic bacterium, designated strain CBA4602(T), was isolated from the gut of the sea cucumber Stichopus japonicus, which was collected from Jeju Island in the Republic of Korea. In a phylogenetic analysis based on the 16S rRNA gene, strain CBA4602(T) belonged to the order Sphingomonadales in the class Alphaproteobacteria. The 16S rRNA gene sequence similarity between strain CBA4602(T) and 'Citromicrobium bathyomarinum' JF-1, the most closely related strain having nonvalidly published name, was 98.4%, followed by 95.2-96.7% identities with sequence of the other closest strains in the genus Erythrobacter. Strain CBA4602(T) had bacteriochlorophyll a and carotenoids. Strain CBA4602(T) grew in 0-10% (w/v) NaCl, at 10-42°C and pH 6.0-8.0, with optimal growth in 1-2% NaCl, at 30-37°C and pH 7.0. Strain CBA4602(T) was positive for catalase and oxidase activities and was able to hydrolyse gelatine and Tween 20 and 40, but not starch, Tween 80 or L-tyrosine. The G+C content of genomic DNA from strain CBA4602(T) was 68.0 mol% and Q-10 was the major detected isoprenoid quinone. The polar lipids were three unidentified phospholipids, three unidentified glycolipids, and two unidentified lipids. The dominant fatty acids were anteiso-C15:0, C16:0, anteiso-C17:0 and C18:0. As considering the current taxonomic status of the genus 'Citromicrobium' and polyphasic taxonomic analyses, strain CBA4602(T) represents a novel genus and species. The name Citrimicrobium luteum is proposed for the type strain CBA4602(T) (=KACC 17668(T) =JCM 19530(T)).

Abstract
A novel Gram-negative, orange-pigmented bacterial strain JLT2008(T) was isolated from the surface seawater of the Western Pacific and subjected to a polyphasic taxonomic study. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain JLT2008(T) belonged to the genus Erythrobacter, sharing the highest similarity (96.6 %) with Erythrobacter gangjinensis K7-2(T) and the lowest similarity (94.9 %) with Erythrobacter litoralis DSM 8509(T). Strain JLT2008(T) did not contain bacteriochlorophyll a, and the predominant respiratory lipoquinone was ubiquinone-10. The major fatty acids were C(18:1) ω7c, C(16:0), C(16:1) ω7c/C(16:1) ω6c. The prominent polar lipids were sphingoglycolipid, phosphatidylethanolamine, and phosphatidylglycerol. The genomic G + C content was 60.1 mol %. Based on the polyphasic taxonomic data, a novel species within the genus Erythrobacter, and with the name Erythrobacter westpacificensis sp. nov., is proposed. The type strain is JLT2008(T) (=CGMCC 1.10993(T) = JCM 18014(T)).
