Abstract

Two Gram-negative, yellow-pigmented bacteria designated PSD1-4 and PHA3-4, isolated from two sand-dune plant species inhabiting coastal areas in Tae-an, Korea, were subjected to taxonomic investigation. 16S rRNA gene sequence analysis indicated that both isolates should be placed in the genus of the family . The phenotypic properties of the strains were also consistent with their classification into this genus. The levels of 16S rRNA gene sequence similarity between strain PSD1-4 and other species were 95·2–97·2 %; those between PHA3-4 and others were 93·7–97·8 %. The DNA–DNA relatedness data indicated that strains PSD1-4 and PHA3-4 were clearly different from the nearest species, and . The major fatty acids were 13-methyltetradecanoic acid (iso-C15 : 0), 3-hydroxy-15-methylhexadecanoic acid (iso-C17 : 0 3-OH) and omega-9--15-methylhexadecenoic acid (iso-C17 : 19) for both strains. On the basis of polyphasic taxonomic analysis results, it is evident that each of these strains represents a novel species of , for which the names sp. nov. (type strain PSD1-4=KCTC 12382=NBRC 100864) and sp. nov. (type strain PHA3-4=KCTC 12381=NBRC 100863) are proposed.
