Marihabitans asiaticum gen. nov., sp. nov., a meso-diaminopimelic acid-containing member of the family Intrasporangiaceae.
Strain HG667(T), isolated from surface seawater collected at the Kesennuma ferry port in Miyagi Prefecture, Japan, was found to be a Gram-positive, catalase-positive bacterium comprising irregular short rods and cocci. The diagnostic diamino acid in the cell-wall peptidoglycan was meso-diaminopimelic acid. The major menaquinone was MK-8(H4). Mycolic acids were not detected. The G+C content of the DNA was 70 mol%. Analysis of the 16S rRNA gene sequence revealed that the strain represents a novel lineage within the family Intrasporangiaceae, order Actinomycetales, being associated with the genus Kribbia. On the basis of morphological, biochemical and chemotaxonomic properties of the strain, together with phylogenetic data relating to the 16S rRNA gene sequence, HG667(T) represents a novel genus and species in the family Intrasporangiaceae, for which the name Marihabitans asiaticum gen. nov., sp. nov. is proposed. The type strain of Marihabitans asiaticum is HG667(T) (=MBIC07497(T) =DSM 18935(T)).
