A Gram-negative, strictly aerobic, yellow-pigmented and rod-shaped bacterium, designated strain NSL10T, was isolated from the waste surface soil of a chemical factory in Hongan, China. Strain NSL10T was found to grow optimally at pH 7.0, 30 °C and in the absence of NaCl in modified LB medium. Cells were found to be positive for catalase and oxidase. The G+C content of the total DNA was determined to be 66.8 mol%. The 16S rRNA gene sequence of strain NSL10T showed the highest similarity to that of Devosia albogilva IPL15T (96.80 %), followed by Devosia geojensis BD-c194T (96.46 %) and Devosia chinhatensis IPL18T (96.27 %). The major cellular fatty acids of strain NSL10T were identified as C18:1 ω7c/C18:1 ω6c (48.2 %) and C16:0 (17.7 %). The major polar lipids were identified as diphosphatidylglycerol, phosphatidylglycerol, two unidentified glycolipids and an unidentified compound. Minor amounts of unidentified glycolipids and unidentified polar lipids were also detected. These chemotaxonomic data supported the affiliation of strain NSL10T to the genus Devosia. In conclusion, on the basis of biochemical, physiological characteristics and molecular properties, strain NSL10T represents a novel species within the genus Devosia, for which the name Devosia honganensis sp. nov., is proposed. The type strain is NSL10T (=KCTC 42281T = ACCC 19737T). Keywords Devosia honganensis sp. nov. Gram-stain negative Taxonomy 16S rRNA gene
