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).", }
