sp. nov., isolated from seawater Free

Abstract

Strains JS54-2 and JS63-1 were isolated from seawater at Jeju, Korea. Cells of these strains were Gram-positive, non-motile, non-spore-forming, short rods and formed yellow-pigmented colonies on tryptic soy agar. The strains had chemotaxonomic markers that were consistent with their classification in the genus , i.e. MK-11, MK-12 and MK-10 as the major menaquinones, fatty acids that were predominantly iso- and anteiso-branched, galactose and glucose as the cell-wall sugars, peptidoglycan-type B2 with glycolyl residues and DNA G+C contents of 69.3–69.6 mol%. A phylogenetic analysis based on 16S rRNA gene sequences showed that the strains were closely related to DSM 16091 and IFO 16062 (with 97.7 and 97.4 % sequence similarity, respectively) and formed a separate lineage with in the genus . Data from DNA–DNA hybridization and phenotypic analyses supported the conclusion that strains JS54-2 and JS63-1 represent a novel species in the genus , for which the name sp. nov. is proposed. The type strain is JS54-2 (=KCTC 19124 =DSM 19713).
