| Abstract |
Three novel filamentous halophilic archaea, strains DFN5T, RDMS1, and QDMS1, were isolated from the coastal saline soil samples of the intertidal zones located in different regions of Jiangsu Province, China. The colonies of these strains were pinkish-white due to the presence of white spores. These three strains are extremely halophilic and grew optimally at 35-37 °C and pH 7.0-7.5. Based on 16S rRNA and rpoB' gene analysis, strains DFN5T, RDMS1, and QDMS1 gathered together in phylogenetic trees and then clustered with the current species of the genus Halocatena showing 96.9-97.4% and 82.2-82.5% similarities, respectively. Both the 16S rRNA gene-based and rpoB' gene-based phylogenies were fully supported by the phylogenomic analysis, and the overall genome-related indexes indicated that strains DFN5T, RDMS1, and QDMS1 should be a novel species of the genus Halocatena. Genome mining revealed that there are considerable differences in the genes related to β-carotene synthesis among these three strains and the current species of Halocatena. The major polar lipids of strains DFN5T, RDMS1, and QDMS1 are PA, PG, PGP-Me, S-TGD-1, TGD-1, and TGD-2. The minor polar lipids, S-DGD-1, DGD-1, S2-DGD, and S-TeGD may be detected. According to the phenotypic characteristics, phylogenetic analysis, genomic and chemotaxonomic features, strains DFN5T (= CGMCC 1.19401 T = JCM 35422 T), RDMS1 (= CGMCC 1.19411) and QDMS1 (= CGMCC 1.19410) were classified as a novel species of the genus Halocatena with the proposed name, Halocatena marina sp. nov. This is the first report of the description of a novel filamentous haloarchaeon isolated from marine intertidal zones. |
