Abstract

A novel halophilic bacterium of the genus Kangiella was isolated from a marine sponge collected from the Florida Keys, USA. Strain A79T, an aerobic, Gram-negative, non-motile, rod-shaped bacterium, grew in 2–15 % (w/v) NaCl, at a temperature of 10–49 °C and at pH 4.5–10. Phylogenetic analysis placed strain A79T in the family Alcanivoraceae in the class Gammaproteobacteria. Strain A79T showed 98.5 % 16S rRNA gene sequence similarity to Kangiella japonica KMM 3899T, 96.6 % similarity to Kangiella koreensis DSM 16069T and 95.6 % similarity to Kangiella aquimarina DSM 16071T. The major cellular fatty acids were iso-C11 : 0, iso-C11 : 0 3-OH, iso-C15 : 0, iso-C17 : 0 and iso-C17 : 1ω9c and the G+C content of the genomic DNA was 44.9 mol%. On the basis of physiological, chemotaxonomic and phylogenetic comparisons, strain A79T represents a novel species in the genus Kangiella, for which the name Kangiella spongicola sp. nov. is proposed. The type strain is A79T ( = ATCC BAA-2076T = DSM 23219T).
