从死海底部沉积物中分离出一种嗜盐细菌。该生物体具有嗜盐细菌的特性，但在两个重要方面与已知物种不同，1）细胞呈盘状，在最佳条件下生长时通常呈杯状，2）对氯化钠的最佳需求量在 1.7-2.5 摩尔范围内，约为一般报道的嗜盐细菌的一半。该生物体被归属于盐杆菌属并被描述为Halobacter volcaniispec.nov。最适合生长的氯化钠浓度接近死海中的浓度。对氯化镁的耐受性非常高；该生物体在含有死海浓度的氯化镁的培养基中生长良好。因此，火山盐杆菌非常适合死海的生命。
A halophilic bacterium was isolated from bottom sediment from the Dead Sea. The organism possessed the properties of the halobacteria, but differed from the known species in two important respects, 1) the cells were disc-shaped and often cupped when grown under optimum conditions, 2) the optimum requirements for sodium chloride was in the range 1.7–2.5 molar which is about half of that generally reported for the halobacteria. The organism was assigned to the genusHalobacteriumand described asHalobacterium volcaniispec.nov. The optimum sodium chloride concentration for growth was close to that found in the Dead Sea. The tolerance for magnesium chloride was very high; the organism grew well in media containing magnesium chloride in the concentrations found in the Dead Sea.Halobacterium volcaniiis therefore remarkably well fitted for life in the Dead Sea.
