Pontibacter sp. nov., isolated from hexachlorocyclohexane-contaminated soil Free

Abstract

An orange-pigmented bacterial strain, designated LP100, was isolated from hexachlorocyclohexane-contaminated soil (Lucknow, India). A neighbour-joining tree based on 16S rRNA gene sequences showed that strain LP100 occupied a distinct phylogenetic position in the species cluster, showing highest similarity with DM9 (97.4 %). Levels of similarity to strains of other species ranged between 94.0 and 96.8 %. Strain LP100 contained MK-7 as the predominant menaquinone and -homospermidine was the major polyamine in the cell. The major cellular fatty acids of strain LP100 were anteiso-C A, iso-C and iso-C H. The polar lipid profile of strain LP100 showed the presence of phosphatidylethanolamine, an unidentified aminophospholipid, three unknown aminolipids and two unknown polar lipids. The G+C content of strain LP100 was 58.2 mol%. The results of DNA–DNA hybridization, biochemical and physiological tests clearly distinguish the novel strain from closely related species of the genus . Therefore, strain LP100 represents a novel species of the genus for which the name is proposed. The type strain is LP100 ( = CCM8435 = MCC2027).
