A bacterial isolate, designated strain THG-MM1T, was isolated from soil in Yongin region, Republic of Korea. Strain THG-MM1T was Gram-stain-negative, aerobic, non-motile and rod-shaped. Based on 16S rRNA gene sequence comparisons, strain THG-MM1T was most closely related to Devosia insulae DS-56T (96.5 % 16S rRNA gene sequence similarity), followed by Devosia yakushimensis Yak96BT (95.7 %) and Devosia albogilva IPL15T (95.2 %). The G+C content of the genomic DNA was 63.7 mol%. The major cellular fatty acids were C16 : 0, summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c) and C18 : 0. The predominant isoprenoid quinone was ubiquinone-10 (Q-10). The major polar lipids were phosphatidylglycerol and an unidentified lipid. The combined phenotypic, chemotaxonomic and phylogenetic data showed that strain THG-MM1T represents a novel species of the genus Devosia, for which the name Devosia humi sp. nov. is proposed, with strain THG-MM1T ( = KACC 18281T = CCTCC AB 2015121T) as the type strain.
从韩国龙仁地区土壤中分离出一株细菌，命名为THG-MM1T菌株。THG-MM1T菌株革兰氏染色阴性，好氧，无运动性，呈杆状。基于16S rRNA基因序列比较，THG-MM1T菌株与岛屿德沃斯氏菌DS-56T（16S rRNA基因序列相似性为96.5%）关系最为密切，其次是屋久岛德沃斯氏菌Yak96BT（95.7%）和白吉尔德沃斯氏菌IPL15T（95.2%）。基因组DNA的G+C含量为63.7mol%。主要细胞脂肪酸为C16 : 0、总和特征8（C18 : 1ω7c和/或C18 : 1ω6c）和C18 : 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和一种未鉴定的脂类。综合表型、化学分类和系统发育数据表明，THG-MM1T菌株代表德沃斯氏菌属的一个新物种，为此提出名为土壤德沃斯氏菌（Devosia humi）的新种，以THG-MM1T菌株（=KACC 18281T = CCTCC AB 2015121T）作为模式菌株。
