Abstract

A halotolerant, Gram-negative, rod-shaped and light-red-pigmented bacterium, designated LP51, was isolated from pond sediment near a hexachlorocyclohexane dumpsite located at Chinhat, Lucknow, India. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain LP51 formed a distinct phyletic clade along with the members of the genus The 16S rRNA gene sequence similarity to members of the genus ranged from 94.2 to 99.4  %. The cells were motile, aerobic and catalase- and oxidase-positive. The major fatty acids were iso-C (17.8  %), iso-C 3-OH (8.8  %), iso-C 3-OH (5.7  %), summed feature 3 (Cω7 and/or Cω6; 6.5  %) and summed feature 4 (iso-C I and/or anteiso-C B; 30.7  %). The polar lipid profile of strain LP51 showed the presence of phosphatidylethanolamine, an unidentified aminophospholipid, unknown aminolipids, unknown polar lipids and unknown glycolipids. DNA–DNA relatedness of strain LP51 with respect to the most closely related type strain, X14-1, was 47.2  %. On the basis of this information, it is proposed that the isolate be assigned to a novel species of the genus , for which the name sp. nov. is proposed. The type strain is LP51 ( = CCM 8436 = MCC 2070).
