Abstract | A polyphasic comparative taxonomic study of Halorubrum ezzemoulense Kharroub et al. 2006, Halorubrum chaoviator Mancinelli et al. 2009 and eight new Halorubrum strains related to these haloarchaeal species was carried out. ... A polyphasic comparative taxonomic study of Halorubrum ezzemoulense Kharroub et al. 2006, Halorubrum chaoviator Mancinelli et al. 2009 and eight new Halorubrum strains related to these haloarchaeal species was carried out. Multilocus sequence analysis using the five concatenated housekeeping genes atpB, EF-2, glnA, ppsA and rpoB’, and phylogenetic analysis based on the 757 core protein sequences obtained from their genomes showed that Hrr. ezzemoulense DSM 17463 T , Hrr. chaoviator Halo-G* T (=DSM 19316 T ) and the eight Halorubrum strains formed a robust cluster, clearly separated from the remaining species of the genus Halorubrum. The orthoANI value and digital DNA-DNA hybridization value, calculated by the Genome-to-Genome Distance Calculator (GGDC), showed percentages among Hrr. ezzemoulense DSM 17463 T , Hrr. chaoviator DSM 19316 T and the eight Halorubrum strains ranging from 99.4 to 97.9 %, and from 95.0 to 74.2 %, respectively, while these values for those strains and the type strains of the most closely related species of Halorubrum were 88.7-77.4% and 36.1- 22.3 %, respectively. Although some differences were observed, the phenotypic and polar lipid profiles were quite similar for all the strains studied. Overall, these data show that Hrr. ezzemoulense, Hrr. chaoviator and the eight new Halorubrum isolates constitute a single species. Thus, Hrr. chaoviator should be considered as a later, heterotypic synonym of Hrr. ezzemoulense. We propose an emended description of Hrr. ezzemoulense, including the features of Hrr. chaoviator and those of the eight new isolates. |
