Abstract：An extremely halophilic C50 carotenoid-producing red archaeon was isolated from the crystalli-zer ponds in solar saltworks.The isolated strain is Gram-negative and short rod.The optimum salinity and pH for growth is 250 and 7,respectively.Phenotypic and molecular analyses of this strain indicated that it belonged to extremely halophilic archaea genus Halorubrum and named Halorubrum Sp1 (16S rRNA Genbank registration number KF697239).UV-visible scanning spectrum showed that C50 carote-noid was the major pigments presented in this strain.Pigment accumulation was maximizing at pH 8. In the salinity range of 150~300,increasing salinity resulted in declined pigment accumulation.
