ABSTRACT
A Gram-stain-negative, non-motile, coccus-shaped, catalase- and oxidase-positive, facultatively anaerobic and pink-pigmented bacterium, designated strain CQN31T, was isolated from sediment of Changqiaohai Lake, Yunnan Province, China. Growth occurred at 4-45 °C (optimum, 37 °C), at pH 6.5-9.5 (optimum, pH 8.0) and with 0-1â% (w/v) NaCl (optimum, 0â%). C18ââ1 ω7c/C18ââ1 ω6c and C16ââ0 were the predominant fatty acids. Phosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidylglycerol (PG), diphosphatidylglycerol (DPG), phosphatidyldimethylethanolamine (PME) and one unidentified aminolipid (AL) were the major polar lipids. The G+C content of the genomic DNA was 71.5â%. 16S rRNA gene sequence comparisons indicated that strain CQN31T shared 96.8â% similarity with Roseomonas wooponensis JCM 19527T and 95.9â% with R. terricola EM0302T. Digital DNA-DNA hybridization values between strain CQN31T and Roseomonas stagni DSM 19981T, R. rosea DSM 14916T and R. mucosa NCTC 13291T were 21.0, 19.4 and 19.8â%, respectively. Average amino acid identity and average nucleotide identity values between strain CQN31T and R. stagni DSM 19981T, R. rosea DSM 14916T and R. mucosa NCTC 13291T were 73.7, 63.4 and 61.9 %, and 79.2, 77.1 and 77.5%, respectively. Distinct morphological, physiological and genotypic differences from previously described taxa support the classification of strain CQN31T as a representative of a novel species in the genus Roseomonas, for which the name Roseomonas bella sp. nov. is proposed. The type strain is CQN31T (=KCTC 62447T=MCCC 1H00309T).
