A diverse range of fermentative bacteria have been isolated from the commercial salterns of Salin-de-Giraud (Camargue, France). One of these isolates, strain SG 3902(T), has many of the morphological and physiological characteristics of the genus Orenia, as was confirmed by a phylogenetic study based on 16S rRNA gene sequencing. The closest species is Orenia marismortui, with a similarity of only 95.1%. However, strain SG 3902(T), unlike O. marismortui, does not ferment mannose, glycogen or starch. The G+C contents of the DNA also differ significantly, being 29.6 mol% for O. marismortui and 33.7 mol% for strain SG 3902(T). On the basis of these physiological and genetic differences, it is proposed that strain SG 3902(T) should be considered as a representative of a new species belonging to the genus Orenia, under the name Orenia salinaria sp. nov. The type strain is SG 3902(T) (=ATCC 700911).
