Two bacterial strains, IPL15T and IPL20T, isolated from a hexachlorocyclohexane dump site in India, were characterized by using a polyphasic approach. Based on 16S rRNA gene sequence analysis, both strains belonged to the genus Devosia; highest sequence similarities of strain IPL15T were observed with Devosia neptuniae J1T and Devosia geojensis BD-c194T (96.2 % in each case) and the highest sequence similarity of strain IPL20T was observed with Devosia soli GH2-10T (98.6 %). Phylogenetic analysis showed the distinct lineages of strains IPL15T and IPL20T among members of the genus Devosia. The presence of C18 : 0 3-OH and C10 : 0 3-OH fatty acids supported their respective positions within the genus Devosia. On the basis of phenotypic characteristics, phylogenetic analysis and DNA–DNA hybridization results, it is concluded that strains IPL15T and IPL20T represent two distinct species of the genus Devosia for which the names Devosia albogilva sp. nov. and Devosia crocina sp. nov., respectively, are proposed. The type strains are Devosia albogilva IPL15T (=CCM 7427T=MTCC 8594T) and Devosia crocina IPL20T (=CCM 7425T=MTCC 8590T).

Abbreviations: HCH, hexachlorocyclohexane; TEM, transmission electron microscope

The GenBank/EMBL/DDBJ accession numbers for the 16S rRNA gene sequences of Devosia albogilva IPL15T and Devosia crocina IPL20T are EF433460 and EF433461, respectively.

Transmission electron micrographs of cells of the two novel strains, DNA–DNA hybridization data for strain IPL20T and related strains, and fatty acid profiles of the two novel strains and related species are available as supplementary material with the online version of this paper.
