abstract= A Gram-staining-negative, non-motile, cream-coloured and rod-shaped bacterium, designated strain LNB2T, was isolated from a hexachlorocyclohexane-contaminated dump site in the village of Ummari, in northern India. The taxonomic position of the novel strain was investigated by using a polyphasic approach. In a phylogenetic analysis based on 16S rRNA gene sequences, strain LNB2T appeared to be most closely related to Sphingomonas haloaromaticamans A175T (98.0 % sequence similarity) and Sphingomonas histidinilytica UM2T (97.3 %). In DNA–DNA hybridizations, the levels of DNA–DNA relatedness between the novel strain and S. haloaromaticamans A175T and S. histidinilytica UM2T were found to be low (8.6 % and 5.6 %, respectively). The genomic DNA G+C content of strain LNB2T was 61.0 mol%. The novel strain’s predominant fatty acids were summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c), C16 : 0, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c), C14 : 0 2-OH, C17 : 1ω6c and 11-methyl C18 : 1ω7c. The major ubiquinone was Q-10, the predominant polyamine was homospermidine, and the major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, sphingoglycolipid, phosphatidylethanolamine and phosphatidyldimethylethanolamine. Based on the phylogenetic, biochemical and chemotaxonomic evidence and the results of the DNA–DNA hybridizations, strain LNB2T represents a novel species of the genus Sphingomonas , for which the name Sphingomonas laterariae sp. nov. is proposed. The type strain is LNB2T ( = MTCC 10873T = CCM 7880T = DSM 25432T).,
