title: Thiobacimonas profunda gen. nov., sp. nov., a member of the family Rhodobacteraceae isolated from deep-sea water.
abstract: A bacterial strain, JLT2016(T), 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 (C18 : 1ω7c and/or C18 : 1ω6c) (60.5 %), C19 : 0 cyclo ω8c (10.9 %) and C16 : 0 (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(T) was Salipiger mucosus A3(T) (96.7 % 16S rRNA gene sequence similarity). The results of phylogenetic analyses with different treeing algorithms indicated that this strain belonged to the Roseobacter clade in the order Rhodobacterales. Based on polyphasic analysis, strain JLT2016(T) is considered to represent a novel genus and species, for which the name Thiobacimonas profunda gen. nov., sp. nov. is proposed. The type strain is JLT2016(T) ( = LMG 27365(T) = CGMCC 1.12377(T)).
