Abstract

A bacterium, named GMD509, showing lipolytic activity was isolated from the eggs of the sea hare collected at Mogiyeo (depth, 12 m), an uninhabited small island in the South Sea of Korea. The strain is Gram-negative, motile, facultatively anaerobic, mesophilic and weakly halophilic. Optimal growth of strain GMD509 occurs in the presence of 3·0 % (w/v) NaCl and at pH 8 and 25 °C. The whole-cell fatty acid profile of the isolate includes C16 : 1, C16 : 0 and C18 : 1 as major fatty acids and its DNA G+C content is 45 mol%. Phylogenetic analyses of 16S rRNA gene sequences place this bacterium in the -, within the genus . The 16S rRNA gene sequence of strain GMD509 is most similar to those of (97·8 %), (97·5 %) and (97·4 %). DNA–DNA relatedness levels between the isolate and its closest known phylogenetic relatives, and , are 25·3 and 13·7 %, respectively. Strain GMD509 therefore represents a novel species, for which the name sp. nov. is proposed, with the type strain GMD509 (=KCTC 12383=JCM 12948).
