Abstract A light cream color colony was isolated, using oligotrophic LB agar medium, from a water sample collected from a tube well and designated as HWB-10T. Cells of strain HWB-10T were Gram-negative, motile rods, nonspore forming, positive for catalase, oxidase, nitrate reduction and esculin. The predominant fatty acids were C16:0, summed feature 4 (C16:1ω7c/iso-C15:0 2-OH) and summed feature 7 (C18:1ω7c, C18:1ω9t and/or C18:1ω12t), and the major ubiquinone was Q-8. NCBI-BLAST- and EzTaxonbased 16S rRNA gene sequence similarity search identified strain HWB-10T as a member of the genus Hydrogenophaga and H. atypica DSM 15342T, H. defulvi DSM 15341T, H. palleronii LMG2366T and H. taeniospiralis LMG7170T being the nearest phylogenetic species with a similarity (%) of 99.3, 99.1, 98.4 and 98.2, respectively, while the similarity was
