Abstract

A marine bacterial strain, designated fav-2-10-05T, was isolated from the mucus layer of a coral of the genus Favia, collected from the coral reef in the Gulf of Eilat, Israel (29.51° N 34.94° E). On the basis of 16S rRNA gene sequence comparisons, strain fav-2-10-05T was affiliated with the family Shewanellaceae. The closest relatives of strain fav-2-10-05T were Shewanella marisflavi SW-117T (96.0% 16S rRNA gene sequence similarity) and Shewanella haliotis DW-1T (95.9 %). Strain fav-2-10-05T was Gram-negative, rod-shaped and motile by means of a single polar flagellum and formed yellow-brownish colonies within 2 days of incubation at 26 °C. Strain fav-2-10-05T demonstrated antibacterial activity against indicator strains and grew in the presence of 0.5-8.0% (w/v) NaCl and at 10-37 6C. The major fatty acids were C 17 : 1ω8c (21.6 %), iso-C15 : 0 (18.6 %), C 15 : 0 (9.1 %) and iso-C13 : 0 (8.9 %). The DNA G+C content was 49.1 mol%. The phylogenetic and phenotypic analyses of strain fav-2-10-05T suggested that it belongs to a novel species of the genus Shewanella, for which the name Shewanella corallii sp. nov. is proposed. The type strain is fav-2-10-05T (=LMG 24563T =DSM 21332T).
