从红树林植物Kandeliacandel（L.）香港米埔自然保护区的德鲁斯。在pH 5.0-8.5（最佳，6.0-7.0）、10-40 °C（30-37 °C）和0- 9%（w/v）NaCl（0.5- 3%）存在下观察到菌株J 95 T的生长。 化学分类学分析表明，主要呼吸醌为泛醌-10，主要脂肪酸为C18：1ω 7 c和C19：0环ω 8。 主要极性脂质为脂类、氨基脂、磷脂、磷脂酰胆碱、磷脂酰甘油和磷脂酰乙醇胺。基因组含有一条5.48 Mb的环状染色体，DNA G+C含量为65.7 mol%。基因组包括5299个基因。基于16 S rRNA基因序列的系统发育分析表明，菌株J 95 T与模式菌株Ruegeria marinaZH 17 T的序列相似性最高，为96.8%。 综合表型、化学分类学和系统发育学数据，J 95 T菌株代表Ruegeria属的一个新种，即Ruegeria kandeliaesp.十一是建议。模式菌株为J 95 T（=MCCC 1 K 03284 T =DSM 104293 T）。
A Gram-negative, rod-shaped and motile bacterium, designated strain J95T, was isolated from the rhizosphere soil of a mangrove plantKandeliacandel(L.) Druce in Mai Po Nature Reserve, Hong Kong. Growth of strain J95Twas observed at pH 5.0–8.5 (optimum, 6.0–7.0), between 10–40 °C (30–37 °C) and in the presence of 0–9 % (w/v) NaCl (0.5–3 %). Chemotaxonomic analysis showed ubiquinone-10 as the predominant respiratory quinone and C18 : 1ω7cand C19 : 0cycloω8cas the major fatty acids. The major polar lipids were lipid, aminolipid, phospholipid, phosphatidylcholine, phosphatidylglycerol and phosphatidylethanolamine. The genomic contained a circular chromosome of 5.48 Mb with a DNA G+C content of 65.7 mol%. The genome included 5299 genes. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain J95Tbelongs to the genusRuegeriawith highest sequence similarity (96.8 %) to the type strainRuegeria marinaZH17T. The combined phenotypic, chemotaxonomic and phylogenetic data suggested that strain J95Trepresents a novel species of the genusRuegeria, for which the nameRuegeria kandeliaesp. nov. is proposed. The type strain is J95T(=MCCC 1K03284T=DSM 104293T).
