An Extremely halophilic bacterium was isolated from solar salts. The isolated strain was Gram-negative, facultatively anaerobic, and motile bacterium. The colony was circular, smooth, and red-orange color. The strain showed pleomorphism depending on magnesium ion concentrations. The range of temperature and pH for growth of the isolate were 35 -45$circ$C and 7.0 - 9.0. NaCl concentration for growth of it was 4.3 - 5.0 M. The isolate was catalase and oxidase positive, and sensitive to bacitracin. It showed starch hydrolyzing and acid forming characteristics. DNA G+C content was 62.7 mol%. The morphological, physiological and biochemical characteristics of the isolate resembled those of the Haloarcula vallismortis, therefore it was identified as Haloarcula sp. EH-1.
