Fulvivirga imtechensis sp. nov., a member of the phylum Bacteroidetes (original) (raw)

2011, International Journal of Systematic and Evolutionary Microbiology

A novel, Gram-staining-negative, yellow-coloured, rod-shaped, obligately aerobic, non-motile bacterium, designated strain AK7T, was isolated from seawater collected on the coast at Visakhapatnam, Andhra Pradesh, India. The predominant fatty acids of the novel strain were iso-C15 : 0, iso-C15 : 0 3-OH, C16 : 1ω5c, iso-C17 : 0 3-OH and summed features 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH) and 4 (iso-C17 : 1 I and/or anteiso-C17 : 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 AK7T appeared most closely related to Fulvivirga kasyanovii KMM 6220T (95.9 % sequence similarity), a member of the family Flammeovirgaceae in the phylum Bacteroidetes . The genomic DNA G+C content of strain AK7T was 55.1 mol%. Based on the morphological, biochemical, physiological, chemotaxonomic and phylogenetic evidence...
