Ivanova eivanova{at}swin.edu.au A yellow-pigmented, non-motile, Gram-negative bacterium, designated Fg 69 T , was isolated from a sediment sample collected in Chazhma Bay (Sea of Japan). The novel organism grew at 10–35 °C, was neutrophilic and required 3–10 % NaCl for optimal growth. Strain Fg 69 T was able to degrade starch and to hydrolyse gelatin and Tween 80 weakly but not casein or agar. Predominant cellular fatty acids comprised n-C 15 and n-C 16 branched-chain and straight-chain saturated and unsaturated fatty acids, including iso-C 15 : 0 (5 %), anteiso-C 15 : 0 (11 %), C 15 : 0 (9 %), iso-C 15 : 1 (5 %), iso-C 16 : 0 (8 %), C 16 : 0 (5 %) and C 16 : 1 7 (5 %) and iso- and anteiso-branched 2-OH and 3-OH C 15 : 0 to C 17 : 0 fatty acids (26 % in total). The G+C content of the DNA was 40·4 mol%. 16S rRNA gene sequence data indicated that strain Fg 69 T belonged to the genus Salegentibacter but was distinct from recognized Salegentibacter species (94–95 % sequence similarity). Based on these results, a novel species, Salegentibacter flavus sp. nov., is proposed. The type strain is Fg 69 T (=KMM 6000 T =CIP 107843 T ). Abbreviations: FAMEs, fatty acid methyl esters The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of strain Fg 69 T is AY682200 .
