Abstract

A Gram-negative, polarly flagellated bacterium was isolated from a sea-water sample collected from the Karadag Natural Reserve of the Eastern Crimea and characterized to clarify its taxonomic position. 16S rRNA gene sequence-based phylogenetic analysis of this novel organism revealed , , , and ‘’ as its closest relatives (similarity 95–97 %). The G+C content of the DNA was 46·5 mol%. The organism grew between 4 and 33 °C, tolerated 10 % NaCl, was slightly alkaliphilic and was not able to degrade starch, gelatin, agar or Tween 80. Phosphatidylethanolamine (53·4 %) and phosphatidylglycerol (46·6 %) were the predominant phospholipids. The major fatty acids were 16 : 0 (15·5 %), 16 : 17 (26·7 %) and 18 : 17 (47·1 %). The phylogenetic, genetic and physiological properties of the organism placed it within a novel species, proposed as sp. nov., the type strain of which is 46-16 (=LMG 22531=KMM 3492=UCM 11075).
