Fulvivirga imtechensis sp. nov., a member of the phylum Bacteroidetes

A novel, Gram-staining-negative, yellow-coloured, rod-shaped, obligately aerobic, non-motile bacterium, designated strain AK7(T), was isolated from seawater collected on the coast at Visakhapatnam, Andhra Pradesh, India. The predominant fatty acids of the novel strain were iso-C(15 : 0), iso-C(15 : 0) 3-OH, C(16 : 1)ω5c, iso-C(17 : 0) 3-OH and summed features 3 (C(16 : 1)ω7c and/or iso-C(15 : 0) 2-OH) and 4 (iso-C(17 : 1) I and/or anteiso-C(17 : 1) B). The major respiratory quinone was MK-7 and the polar lipid profile comprised phosphatidylethanolamine, two unidentified aminolipids and four other unidentified lipids. In phylogenetic analysis based on 16S rRNA gene sequences, strain AK7(T) appeared most closely related to Fulvivirga kasyanovii KMM 6220(T) (95.9 % sequence similarity), a member of the family Flammeovirgaceae in the phylum Bacteroidetes. The genomic DNA G+C content of strain AK7(T) was 55.1 mol%. Based on the morphological, biochemical, physiological, chemotaxonomic and phylogenetic evidence, strain AK7(T) represents a novel species of the genus Fulvivirga for which the name Fulvivirga imtechensis sp. nov. is proposed. The type strain is AK7(T) (= MTCC 11053(T) = JCM 17390(T)).
