Four extremely halophilic archaeal strains, LYG-108T, LYG-24, DT1T and YSSS71, were isolated from salted Laminaria produced in Lianyungang and saline soil from the coastal beach at Jiangsu, PR China. The four strains were found to be related to the current species of Halomicroarcula (showing 88.1–98.5% and 89.3–93.6% similarities, respectively) as revealed by phylogenetic analysis based on 16S rRNA and rpoB′ genes. These phylogenies were fully supported by the phylogenomic analysis, and the overall genome-related indexes (average nucleotide identity, DNA–DNA hybridization and average amino acid identity) among these four strains and the Halomicroarcula species were 77–84 %, 23–30 % and 71–83 %, respectively, clearly below the threshold values for species demarcation. Additionally, the phylogenomic and comparative genomic analyses revealed that Halomicroarcula salina YGH18T is related to the current species of Haloarcula rather than those of Halomicroarcula , Haloarcula salaria Namwong et al. 2011 is a later heterotypic synonym of Haloarcula argentinensis Ihara et al. 1997, and Haloarcula quadrata Oren et al. 1999 is a later heterotypic synonym of Haloarcula marismortui Oren et al. 1990. The major polar lipids of strains LYG-108T, LYG-24, DT1T and YSSS71 were phosphatidylglycerol, phosphatidylglycerol phosphate methyl ester, phosphatidylglycerol sulphate, sulphated mannosyl glucosyl diether and additional glycosyl-cardiolipins. All these results showed that strains LYG-108T (=CGMCC 1.13607T=JCM 32950T) and LYG-24 (=CGMCC 1.13605=JCM 32949) represent a new species of the genus Halomicroarcula , for which the name Halomicroarcula laminariae sp. nov. is proposed; strains DT1T (=CGMCC 1.18928T=JCM 35414T) and YSSS71 (=CGMCC 1.18783=JCM 34915) also represent a new species of the genus Halomicroarcula , for which the name Halomicroarcula marina sp. nov. is proposed.

“…The complete genomes of strains Gai3-17 T and XZYJT26 T were sequenced and assembled as described previously [28]. The JSpeciesWS online ANI calculator [29], the Genome-to-Genome Distance Calculator 3.0 [30] and an AAI calculator [31] were used to calculate the average nucleotide identity (ANI), digital DNA-DNA hybridization (dDDH) and the average amino acid identity (AAI) values, respectively.…”

Two novel halophilic archaeal strains, Gai3-17T and XZYJT26T, were isolated from the sediment of Gaize salt lake and the saline soil of Mangkang ancient solar saltern in Tibet, PR China, respectively. Strains Gai3-17T and XZYJT26T were related to each other (96.5 and 89.7% similarity, respectively) and showed 97.5–95.4 and 91.5–87.7% similarities to the current members of Halobacterium based on 16S rRNA and rpoB′ genes. The phylogenomic analysis indicated that strains Gai3-17T and XZYJT26T formed two distinct clades and clustered with the Halobacterium species. The two strains can be differentiated from the type strains of the six species with validly published names based on several phenotypic characteristics. The phospholipids of the two strains were phosphatidic acid, phosphatidylglycerol and phosphatidylglycerol phosphate methyl ester. One major glycolipid, sulphated galactosyl mannosyl glucosyl diether, was detected in strain Gai3-17T, while four glycolipids, mannosyl glucosyl diether, sulphated mannosyl glucosyl diether, disulphated mannosyl glucosyl diether and sulphated galactosyl mannosyl glucosyl diether were observed in strain XZYJT26T. The average nucleotide identity, digital DNA–DNA hybridization and amino acid identity values among the two strains and the members of Halobacterium were no more than 81, 25 and 77 %, respectively. These overall genome-related indices were below the threshold values for species boundary, indicating that strains Gai3-17T and XZYJT26T represent two novel species of Halobacterium . Thus, two novel species, Halobacterium wangiae sp. nov. and Halobacterium zhouii sp. nov., are proposed to accommodate strains Gai3-17T (=CGMCC 1.16101T=JCM 33551T) and XZYJT26T (=CGMCC 1.16682T=JCM 33556T), respectively.

Five halophilic archaeal strains (AGai3-5T, KZCA101T, CGA3T, WLHS1T and WLHSJ1T) were isolated from salt lakes and soda lakes in PR China. These strains had low 16S rRNA gene similarities (91.3–96.0 %) to closely related species of the family Natrialbaceae and may represent a new genus of the family. Phylogenetic and phylogenomic analyses revealed that these strains formed a distinct clade, separate from the nearby genera Natronobiforma and Saliphagus . The average nucleotide identity, digital DNA–DNA hybridization and average amino acid identity (AAI) values among these five strains and the current members of the family Natrialbaceae were 72–90, 20–42 and 62–91 %, respectively, clearly below the threshold values for species demarcation. According to the critical value of AAI (≤76 %) proposed to differentiate genera within the family Natrialbaceae , it was further indicated that these strains represented a novel genus within the family. These strains could be distinguished from the related genera according to differential phenotypic characteristics. The major lipids of these strains were phosphatidic acid (PA), phosphatidylglycerol, phosphatidylglycerol phosphate methyl ester, mannosyl glucosyl diether (DGD-PA), sulphated DGD-1 (S-DGD-PA) and sulphated galactosyl mannosyl glucosyl diether. The phenotypic, chemotaxonomic, phylogenetic and phylogenomic features indicated that strains AGai3-5T (=CGMCC 1.16078T=JCM 33549T), KZCA101T (=CGMCC 1.17431T=JCM 35074T), CGA3T (=CGMCC 1.17463T=JCM 34318T), WLHS1T (=CGMCC 1.13780T=JCM 33562T) and WLHSJ1T (=CGMCC 1.13784T=JCM 33563T) represent five novel species of a new genus within the family Natrialbaceae , named Natronosalvus halobius gen. nov., sp. nov., Natronosalvus caseinilyticus sp. nov., Natronosalvus vescus sp. nov., Natronosalvus rutilus sp. nov. and Natronosalvus amylolyticus sp. nov., respectively.
