  • Title: Maribacter chungangensis sp. nov., isolated from a green seaweed, and emended descriptions of the genus Maribacter and Maribacter arcticus.

    Journal: Int J Syst Evol Microbiol; 2013 Jul; 63(Pt 7):2553-2558. PubMed ID: 23243094.
    Abstract:
    A Gram-stain-negative, non-spore-forming, strictly aerobic, orange-pigmented bacterial strain, motile by gliding, designated CAU 1044(T), was isolated from a green seaweed and its taxonomic position was investigated using a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain CAU 1044(T) formed a distinct lineage within the genus Maribacter and was most closely related to Maribacter antarcticus JCM 15445(T) and Maribacter arcticus KOPRI 20941(T) (96.3 and 95.7 % similarity, respectively). Strain CAU 1044(T) contained menaquinone 6 as the only isoprenoid quinone and iso-C15 : 0, summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c and/or iso-C15 : 0 2-OH), iso-C17 : 0 3-OH and iso-C15 : 1 G as the major fatty acids. The cell wall peptidoglycan of strain CAU 1044(T) contained meso-diaminopimelic acid and the major whole-cell sugars were glucose and ribose. The polar lipids were composed of phosphatidylethanolamine, one unidentified phospholipid, six unidentified aminolipids and four unidentified lipids. The DNA G+C content was 40.2 mol%. On the basis of phenotypic data and phylogenetic inference, strain CAU 1044(T) should be classified as a representative of a novel species in the genus Maribacter for which the name Maribacter chungangensis sp. nov. is proposed. The type strain is CAU 1044(T) ( = KCTC 23735(T) = CCUG 61948(T)). Emended descriptions of the genus Maribacter and the species M. arcticus KCTC 22053(T) are also proposed.
