Devosia litorisediminis sp. nov., isolated from a sand dune

초록

A Gram-negative, aerobic, non-motile, and rod-shaped bacterial strain, designated BSSL-BM10(T), was isolated from sand of a dune that was collected from the Yellow Sea, Republic of Korea. It was subjected to a polyphasic taxonomic study. 16S rRNA gene sequence analysis showed that strain BSSL-BM10(T) fell phylogenetically within the radiation comprising type strains of Devosia species. The 16S rRNA gene sequence of strain BSSL-BM10(T) shared sequence similarities of 98.2% with the type strain of D. naphthalenivorans and 93.5-97.7% with type strains of other Devosia species. ANI and dDDH values between strain BSSL-BM10(T) and type strains of 18 Devosia species were 71.0-78.4% and 18.8-21.5%, respectively. The DNA G + C content of strain BSSL-BM10(T) was 60.9% based on its genomic sequence data. Strain BSSL-BM10(T) contained Q-10 as the predominant ubiquinone and 11-methyl C-18:1 omega 7c, C-18:1 omega 7c, summed feature 3 (C-16:1 omega 7c and/or C-16:1 omega 6c), and C-16:0 as its major fatty acids. Major polar lipids of strain BSSL-BM10(T) were phosphatidylglycerol and two unidentified glycolipids. Strain BSSL-BM10(T) showed distinguishable phenotypic properties with its phylogenetic and genetic distinctiveness separated from recognized Devosia species. Based on data presented in this study, strain BSSL-BM10(T) should be placed in the genus Devosia. The name Devosia litorisediminis sp. nov. is proposed for strain BSSL-BM10(T) (= KACC 21633(T) = NBRC 115152(T)).
