title: Oceanibaculum pacificum sp. nov., isolated from hydrothermal field sediment of the south-west Pacific Ocean.
abstract: A taxonomic study was carried out on strain LMC2up-L3(T), which was isolated from a polycyclic aromatic hydrocarbon-degrading consortium enriched with a sediment sample collected from a hydrothermal field of the south-west Pacific Ocean. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain LMC2up-L3(T) belonged to the genus Oceanibaculum, with the highest sequence similarity of 98.4 % to Oceanibaculum indicum P24(T); similarity to other strains was below 93.1 %. DNA-DNA hybridization between strain LMC2up-L3(T) and O. indicum P24(T) was 31 %. rep-PCR fingerprints also differentiated strain LMC2up-L3(T) from O. indicum P24(T). The G+C content of the chromosomal DNA was 67.7 mol%. The principal fatty acids were C(16 : 1) (17.8 %), C(16 : 0) (21.2 %), C(18 : 1)omega7c (23.6 %), C(18 : 0) (4.1 %), C(18 : 1) 2-OH (4.5 %) and C(19 : 0) cyclo omega8c (17.4 %). The combined genotypic and phenotypic data show that strain LMC2up-L3(T) represents a novel species of the genus Oceanibaculum, for which the name Oceanibaculum pacificum sp. nov. is proposed, with the type strain LMC2up-L3(T) (=CCTCC AB 209059(T) =LMG 24859(T) =MCCC 1A02656(T)). An emended description of the genus Oceanibaculum is also provided.
