Growth of strain 011410T was observed at 4–41 °C (optimum, 30 °C), at pH 4.5–10.0 (optimum, pH 8.0) and at salinities of 0–10 % (w/v) NaCl (optimum, 0–2 %). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain 011410T was a member of the genus Paracoccus and was related most closely to Paracoccus aestuarii B7T (96.62 % similarity) and Paracoccus sediminis CMB17T (96.48 % similarity). The major fatty acid was identified as C18 : 1ω7c, with smaller amounts of C18 : 0, C10 : 0 3-OH and summed feature 2 (C14 : 0 3-OH and/or iso-C16 : 1 I). The predominant respiratory quinone was ubiquinone-10 (Q-10), with Q-9 as a minor component. Polar lipid analysis indicated the presence of diphosphatidylglycerol, phosphatidylglycerol, one unknown phosphoglycolipid, five unknown phospholipids, one unknown aminolipid, one unknown glycolipid and two unknown polar lipids. The DNA G+C content of the strain was 63.5 mol%. On the basis of the data from this polyphasic characterization, strain 011410T represents a novel species, for which the name Paracoccus aerius sp. nov. is proposed. The type strain is 011410T (=CFCC 14285T=KCTC 42845T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.001976
