A novel Gram-stain-negative rod-shaped gliding bacterial strain, designated 35/09T, was isolated from diseased European sea bass (Dicentrarchus labrax L.) in Spain. Colonies were pale-yellow-pigmented with uneven edges and did not adhere to the agar. The DNA G+C content of the isolate was 31.3 mol%. 16S rRNA gene sequence analysis indicated affiliation to the genus Tenacibaculum (family Flavobacteriaceae, phylum ‘Bacteroidetes’). Sequence similarities between the isolate and type strains of other members of the genus were 93.1–97.3 %. The major fatty acids (>5 % of the total fatty acids) were iso-C15 : 0 (24.8 %), iso-C15 : 0 3-OH (18.0 %), anteiso-C15 : 0 (8.1 %), C15 : 1Ï6c (6.9 %) and iso-C15 : 1 (6.2 %). Genotypic and phenotypic data indicate that strain 35/09T should be classified as a representative of a novel species in the genus Tenacibaculum, for which the name Tenacibaculum dicentrarchi sp. nov. is proposed; the type strain is 35/09T ( = CECT 7612T = NCIMB 14598T).
