Litoribrevibacter euphylliae sp. nov., isolated from the torch coral Euphyllia glabrescens

Strain Eup a-2^T, isolated from the torch coral Euphyllia glabrescens, was characterized using a polyphasic taxonomy approach. Cells of strain Eup a-2^T were Gram-negative, aerobic and motile by three polar flagella and formed translucent colonies. Optimal growth occurred at 25 °C, pH 6-8 and in the presence of 2-4 % NaCl. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain Eup a-2^T belonged to the genus Litoribrevibacter and showed the highest levels of sequence similarity with respect to Litoribrevibacter albus Y32^T (97.8 %). Strain Eup a-2^T contained summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and C16 : 0 as the predominant fatty acids. The predominant isoprenoid quinone was Q-8. The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol and diphophatidylglycerol. Genomic DNA G+C content of strain Eup a-2^T was 49.1 mol%. The DNA-DNA hybridization value for strain Eup a-2^T with L. albus Y32^T was less than 30 %. Differential phenotypic properties, together with the phylogenetic inference, demonstrate that strain Eup a-2^T should be classified as a novel species of the genus Litoribrevibacter, for which the name Litoribrevibactereuphylliae sp. nov. is presented. The type strain is Eup a-2^T (=BCRC 81004^T=LMG 29725^T=KCTC 52438^T).
