RT Journal Article SR Electronic(1) A1 Lai, Qiliang A1 Yuan, Jun A1 Shao, ZongzeYR 2009 T1 Maribaculum marinum gen. nov., sp. nov., isolated from deep seawater JF International Journal of Systematic and Evolutionary Microbiology, VO 59 IS 12 SP 3083 OP 3087 DO https://doi.org/10.1099/ijs.0.008177-0 PB Microbiology Society, SN 1466-5034, AB A taxonomic study was carried out on strain P38T, which was isolated from an enriched polycyclic aromatic hydrocarbon-degrading consortium from a deep seawater sample collected from the Indian Ocean. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain P38T formed a distinct evolutionary lineage within the family Hyphomonadaceae. Strain P38T was most closely related to members of the genera Hyphomonas (92.3–93.5 % 16S rRNA gene sequence similarity), Hirschia (88.8 %), Maricaulis (88.3–88.6 %), Hellea (87.5 %), Oceanicaulis (87.4 %) and Robiginitomaculum (86.7 %) of the family Hyphomonadaceae. The DNA G+C content of strain P38T was 61.0 mol% and the predominant cellular fatty acids were C16 : 0 (20 %), C17 : 0 (5.7 %), C18 : 1 ω7c (37.7 %), C18 : 0 (6.3 %) and C18 : 1 ω7c 11-methyl (7.1 %). Strain P38T was distinguishable from members of phylogenetically related genera by differences in several phenotypic properties. On the basis of the phenotypic and phylogenetic data, strain P38T represents a novel species of a new genus, for which the name Maribaculum marinum gen. nov., sp. nov. is proposed. The type strain of Maribaculum marinum is P38T (=CCTCC AB 208227T=LMG 24711T=MCCC 1A01086T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.008177-0
