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 0–1 % (w/v) NaCl (optimum, 0 %). C18 : 1ω7c/C18 : 1ω6cand C16 : 0were 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 71.5 %. 16S rRNA gene sequence comparisons indicated that strain CQN31Tshared 96.8 % similarity withRoseomonas wooponensisJCM 19527Tand 95.9 % withR. terricolaEM0302T. Digital DNA–DNA hybridization values between strain CQN31TandRoseomonas stagniDSM 19981T,R. roseaDSM 14916TandR. mucosaNCTC 13291Twere 21.0, 19.4 and 19.8 %, respectively. Average amino acid identity and average nucleotide identity values between strain CQN31TandR. stagniDSM 19981T,R. roseaDSM 14916TandR. mucosaNCTC 13291Twere 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 CQN31Tas a representative of a novel species in the genusRoseomonas, for which the nameRoseomonas bellasp. nov. is proposed. The type strain is CQN31T(=KCTC 62447T=MCCC 1H00309T).
