Abstract

A bacterial strain, JLT2016, was isolated from a sample of South-eastern Pacific deep-sea water. Cells were Gram-stain-negative, aerobic, devoid of flagella, motile by gliding and rod-shaped. Colonies were mucoid and cream. Growth occurred at 1.0–11.0 % (w/v) NaCl, 10–40 °C and pH 4.0–9.0. The major fatty acids were summed feature 8 (Cω7 and/or Cω6) (60.5 %), C cyclo ω8 (10.9 %) and C (9.0 %). The polar lipids included diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and two sphingoglycolipids. The DNA G+C content was 67.1 mol%. The closest relative of strain JLT2016 was A3 (96.7 % 16S rRNA gene sequence similarity). The results of phylogenetic analyses with different treeing algorithms indicated that this strain belonged to the clade in the order . Based on polyphasic analysis, strain JLT2016 is considered to represent a novel genus and species, for which the name gen. nov., sp. nov. is proposed. The type strain is JLT2016 ( = LMG 27365 = CGMCC 1.12377).
