title: Halobacterium piscisalsi Yachai et al. 2008 is a later heterotypic synonym of Halobacterium salinarum Elazari-Volcani 1957.
abstract: Halobacterium piscisalsi was proposed by Yachai et al. (2008), with a single strain, HPC1-2(T) (= BCC 24372(T) = JCM 14661(T) = PCU 302(T)), which was isolated from fermented fish (pla-ra) in Thailand. According to Yachai et al. (2008), the strain was closely related to Halobacterium salinarum based on 16S rRNA gene sequence comparisons and could be differentiated by low DNA-DNA relatedness values and different biochemical profiles compared with other species of the genus. The reanalysis of the 16S rRNA gene sequences and the DNA-DNA relatedness among H. piscisalsi JCM 14661(T) and H. salinarum strains JCM 8978(T), R1 and NRC-1 revealed that they all had exactly the same 16S rRNA gene sequence and shared more than 70 % DNA-DNA relatedness. In addition, the full-length DNA-dependent RNA polymerase subunit B (RpoB) protein sequence of H. piscisalsi JCM 14661(T) (607 amino acids) was the same as that of H. salinarum JCM 8978(T) and showed 94.7 and 96.7 % similarities with those of Halobacterium noricense JCM 15102(T) and Halobacterium jilantaiense JCM 13558(T), respectively. Despite the different biochemical properties described by Yachai et al. (2008), the characteristic phenotypic properties of H. piscisalsi agreed with those in the description of H. salinarum emended by Gruber et al. (2004). Therefore, H. piscisalsi Yachai et al. (2008) should be regarded as a later heterotypic synonym of H. salinarum Elazari-Volcani 1957.
