Deleya halophila, a New Species of Moderately Halophilic Bacteria

Abstract

Deleya halophila sp. nov., which was isolated from hypersaline soils, is proposed. Each of 38 isolates, together with 8 reference strains, was examined in 97 phenotypic tests, and the data were analyzed by numerical taxonomy procedures. The 38 isolates formed a distinct group at a 76% similarity value, as determined by an analysis performed with the simple matching coefficient and unweighted average linkage clustering. Characteristically, the isolates were aerobic, gram-negative rods that were motile by one to eight peritrichous flagella. They grew optimally in the presence of 7.5% (wt/vol) marine salts. The distinguishing features of the new species are its salt requirement, biochemical features, and nutritional versatility. The guanine-plus-cytosine content of the deoxyribonucleic acid is 66.7 mol%. The type strain of this species is strain F5-7 (= CCM 3662).
