A bacterial isolate, designated strain S37T, was isolated from the rhizosphere of oil palm (Elaeis guineensis). Strain S37T was found to be Gram-stain-negative, aerobic, motile and rod shaped. Based on 16S rRNA gene sequence analysis, strain S37T was most closely related to Devosia albogilva IPL15T (97.3 %), Devosia chinhatensis IPL18T (96.8 %) and Devosia subaequoris HST3-14T (96.5 %). The G+C content of the genomic DNA was 63.0 mol%, and dominant cellular fatty acids were summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c), 11-methyl C18 : 1ω7c and C16 : 0. The predominant isoprenoid quinone was ubiquinone-10 (Q-10), and the major polar lipids were phosphatidylglycerol, diphosphatidylglycerol, glycolipid and phospholipids. Based on the polyphasic taxonomic data, it is clear that strain S37T represents a novel species of the genus Devosia within the family Hyphomicrobiaceae, for which we propose the name Devosia elaeis sp. nov., with strain S37T (=TBRC 5145T=LMG 29420T) as the type strain.
从油棕（Elaeis guineensis）根际分离出一株细菌，命名为S37T菌株。发现S37T菌株革兰氏染色阴性、需氧、具运动性且呈杆状。基于16S rRNA基因序列分析，S37T菌株与白吉尔德沃斯氏菌IPL15T（97.3%）、钦哈塔德沃斯氏菌IPL18T（96.8%）和亚等角德沃斯氏菌HST3 - 14T（96.5%）亲缘关系最近。基因组DNA的G + C含量为63.0摩尔%，主要细胞脂肪酸为特征性总和8（C18:1ω7c和/或C18:1ω6c）、11 - 甲基C18:1ω7c和C16:0。主要类异戊二烯醌为泛醌 - 10（Q - 10），主要极性脂为磷脂酰甘油、双磷脂酰甘油、糖脂和磷脂。基于多相分类学数据，很明显S37T菌株代表了生丝微菌科德沃斯氏菌属的一个新物种，我们将其命名为油棕德沃斯氏菌（Devosia elaeis）新种，以S37T菌株（=TBRC 5145T = LMG 29420T）作为模式菌株。
