Cells were orange, non-motile cocci with oxidase- and catalase-positive activities and did not contain bacteriochlorophyll a. Growth of strain HC1T was observed at 10–45 °C (optimum, 30 °C), pH 4.5–9.5 (optimum, pH 7.0) and 0–3 % (w/v) NaCl (optimum, 0 %). Strain HC1T contained summed feature 8 (comprising C18 : 1ω7c/C18  : 1ω6c), C16 : 0 and cyclo-C19 : 0ω8c as the major fatty acids and ubiquinone-10 as the sole isoprenoid quinone. Phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine and an unknown aminolipid were detected as the major polar lipids. The major carotenoid was hydroxyspirilloxanthin. The G+C content of the genomic DNA was 70.1 mol%. Phylogenetic analysis, based on 16S rRNA gene sequences, showed that strain HC1T formed a phylogenetic lineage within the genus Roseomonas . Strain HC1T was most closely related to the type strains of Roseomonas oryzae , Roseomonas rubra , Roseomonas aestuarii and Roseomonas rhizosphaerae with 98.1, 97.9, 97.6 and 96.8 % 16S rRNA gene sequence similarities, respectively, but the DNA–DNA relatedness values between strain HC1T and closely related type strains were less than 70 %. Based on phenotypic, chemotaxonomic and molecular properties, strain HC1T represents a novel species of the genus Roseomonas , for which the name Roseomonas aerofrigidensis sp. nov. is proposed. The type strain is HC1T (=KACC 19097T=JCM 31878T).", }
