Strain L15T, a Gram-negative, motile, orange colored bacterium was isolated from pond soil in the surrounding area of a hexachlorocyclohexane (HCH) dump site at Ummari village in Lucknow, India. Phylogenetic analysis based on 16S rRNA gene sequence showed that strain L15T belongs to the family Hyphomicrobiaceae in the order Rhizobiales. Strain L15T showed highest 16S rRNA gene sequence similarity to Devosia chinhatensis IPL18T (98.0%). Chemotaxonomic data revealed that the major fatty acids were summed feature 8 (C18:1 ω7c and/or C18:1 ω6c), C18:1 ω7c 11-methyl, C16:0 and C18:0. The major polar lipids of strain L15T were diphosphatidylglycerol and phosphatidylglycerol. The genomic DNA G+C content of strain L15T was 59.8%. Polyamine profile showed the presence of sym-homospermidine with traces of putrescine. Ubiquinone Q-10 was the major respiratory quinone present. Based on these data, strain L15T (=CCM 7977T =DSM 25398T) was classified as a type strain of a novel species, for which the name Devosia lucknowensis sp. nov. is proposed.
