Two moderately halophilic Gram-negative bacteria were isolated from a sample taken from the brine-seawater interface of the Shaban Deep in the Red Sea. Phylogenetic analysis of the 16S rRNA gene sequence showed that these organisms represent a novel species of the genus Marinobacter. Cells of the new isolates formed non-pigmented colonies and were motile by means of a single polar flagellum. Strains SD-14B(T) and SD-14C grew optimally at 35-37 degrees C, in 5% NaCl and at pH 7.5-8.0. The organisms were aerobic, but reduced nitrate to nitrogen under anaerobic conditions. Acid was produced from only a few carbohydrates. Ubiquinone 9 was the major respiratory quinone. The major fatty acids of strains SD-14B(T) and SD-14C were C-16:0, C-18:1 omega 9c, summed feature 3 (C-16:1 omega 6c/C-16:1 omega 7c) and C-12:0 3-OH. The DNA G + C contents were 55.9 and 55.7 mol%, respectively. On the basis of the phylogenetic analyses and physiological and biochemical characteristics, it is proposed that strains SD-14B(T) and SD-14C represent a novel species of the genus Marinobacter, with the name Marinobacter salsuginis sp. nov. The type strain is strain SD-14B(T) (=DSM 18347(T) =LMG 23697(T)).
