A white-coloured bacterium, SGM1-15(T), was isolated from a paddy soil sample from Suwon, Republic of Korea. The cells were strictly aerobic, Gram-negative and curved rod-shaped. A phylogenetic analysis based on 16S rRNA gene sequences revealed that strain SGM1-15(T) was closely related to Curvibacter delicatus LMG 4328(T) (97.6% similarity) and Caenimonas koreensis EMB320(T) (97.5% similarity). The major respiratory quinone system was Q-8 and the predominant cellular fatty acids were C(16:0) (39.9%), summed feature 3 (C(16:1) ω7c and/or iso-C(15:0) 2-OH; 24.3%) and C(17:0) cyclo (22.7%). The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. The major polyamines were 2-hydroxypurescine, purescine and spermidine. The DNA G+C content was 68.7 mol%. On the basis of the phylogenetic, physiologicl and chemotaxonomic data, stain SGM1-15(T) represents a novel species of the genus Caenimonas, for which the name Caenimonas terrae sp. nov. is proposed. The type strain of Caenimonas terrae is SGM1-15(T) (=KACC 13365(T) =NBRC 106341(T)).
一株白色杆菌，SGM1-15(T)，从韩国水原的稻田土壤样本中分离得到。细胞严格需氧，革兰氏阴性，呈弯曲杆状。基于 16S rRNA 基因序列的系统发育分析表明，菌株 SGM1-15(T)与 Curvibacter delicatus LMG 4328(T)（相似度 97.6%）和 Caenimonas koreensis EMB320(T)（相似度 97.5%）密切相关。主要呼吸醌系统为 Q-8，主要细胞脂肪酸为 C(16:0)（39.9%）、特征脂肪酸 3（C(16:1) ω7c 和/或 iso-C(15:0) 2-OH；24.3%）和 C(17:0) 环（22.7%）。主要极性脂为双磷脂酰甘油、磷脂酰甘油和磷脂酰乙醇胺。主要多胺为 2-羟嘌呤、嘌呤和亚精胺。DNA G+C 含量为 68.7 mol%。基于系统发育、生理和化学分类学数据，菌株 SGM1-15(T)代表了 Caenimonas 属的一个新种，命名为 Caenimonas terrae sp. nov.。Caenimonas terrae 的模式菌株为 SGM1-15(T)=KACC 13365(T)=NBRC 106341(T)。
