Abstract

Two novel exopolysaccharide-producing bacteria, strains S18K6 and S18K5, were isolated from Pacific Ocean sediment. The isolates were Gram-negative, motile, strictly aerobic chemoheterotrophic bacteria. The DNA G+C contents of strains S18K6 and S18K5 were 44.8 and 46.3 mol%, respectively. DNA–DNA relatedness between the two strains was 70 %. Major fatty acids were hexadecanoic acid (C), hexadecenoic acid (C 7) and octadecenoic acid (C 7). 16S rRNA gene sequence, chemotaxonomic and morphological data indicated that these strains clearly belonged to the genus . Based on phenotypic properties and DNA–DNA hybridization data, strains S18K6 and S18K5 are considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is S18K6 (=JCM 13645=NCIMB 14146).
