A Gram-stain-negative, motile, red pigmented, rod-shaped bacterium, designated strain LP43(T), was isolated from hexachlorocyclohexane (HCH)-contaminated soil sediment (Lucknow, India). Phylogenetic analysis based on 16S rRNA gene sequences indicated that the isolate formed a cluster with the genus Pontibacter in the phylum Bacteroidetes with sequence similarities ranging from 92.9 to 97.0% with species of the genus Pontibacter. The DNA G C content of strain LP43(T) was 59.1 mol%. The polar lipid profile of strain LP43(T) showed the presence of phosphatidylethanolamine, an unidentified aminophospholipid, unknown aminolipids and unknown polar lipids. Strain LP43(T) contained MK-7 as the predominant menaquinone and sym-homospermidine as the major polyamine. The major cellular fatty acids of strain LP43(T) were, iso-C-15:0 (15.74%), iso-C-15:0 3-OH (7.57%), iso-C-17:0 3-OH (7.32%), summed feature 4 (iso-C-17:1 I/anteiso-C-17:1 B) (31.22%) and summed feature 8 (C-18:1 omega 7c/ C-18:1 omega 6c (7.60%). Based on the results of DNA-DNA hybridization and phenotypic and genotypic characteristics, strain LP43(T) represents a novel species of the genus Pontibacter, for which the name Pontibacter ramchanderi is proposed. The type strain is LP43(T) (=CCM 8406(T)=MCC 2019(T)).
