Abstract:
The taxonomic status of an actinobacterium that changed colour during growth, strain 42H12-1 T , isolated from deep-sea sediment collected from the Atlantic Ocean, was established using a combination of genotypic and phenotypic data. Strain 42H12-1 T formed a distinct branch in the 16S rRNA gene phylogenetic tree together with the type strains in the genus Modestobacter . The highest sequence similarity by blast analysis was to Modestobacter versicolor CP153-2 T (98.5 %) and the second-highest sequence similarity was to Modestobacter multiseptatus AA-826 T (97.5 %). DNA–DNA relatedness of only 12 % ( sd 1.82 %) between strain 42H12-1 T and M . versicolor DSM 16678 T differentiated them as members of separate genomic species. Colonies of strain 42H12-1 T were black on oligotrophic medium, but orange to red, turning black, on copiotrophic medium. The peptidoglycan contained meso -diaminopimelic acid. The polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol and an unknown aminophospholipid. The predominant menaquinone was MK-9(H 4 ). The major fatty acids were iso-C 16 : 0 and C 17 : 1 ω8 c . The DNA G + C content was 72.3±1 mol%. Strain 42H12-1 T ( = DSM 45201 T = CGMCC 4.5581 T ) is assigned as the type strain of a novel species of the genus Modestobacter , for which the name Modestobacter marinus sp. nov. is proposed.
