Sequence Similarities

An extremely halophilic archaeon (strain 7-3T) was isolated from Aibi salt lake in Xin-Jiang, China. It formed small (<1.0 mm), red, elevated colonies on salt-milk agar medium. Strain 7-3T was able to grow at pH 6.5–9.5 (optimum pH 8.0) and at 20–50 °C (optimum 45 °C). Analysis of its 16S rRNA gene sequence indicated that strain 7-3T was phylogenetically related to members of the genus Natronorubrum, with sequence similarities of 97.0 % to Natronorubrum bangense A33T and 95.2 % to Natronorubrum tibetense GA33T. The G+C content of its DNA was 61.2 mol% (T m). Levels of DNA–DNA relatedness to Nrr. bangense and Nrr. tibetense were 45 and 37 %, respectively. It is concluded that strain 7-3T (=CGMCC 1.4299T=JCM 13488T) should be classified as the type strain of a novel species of the genus Natronorubrum, for which the name Natronorubrum aibiense sp. nov. is proposed. Based on the properties of Nrr. aibiense given here and of those of Nrr. bangense and Nrr. tibetense described previously, an emended description of the genus Natronorubrum is presented.

Extremely Halophilic Archaeon

A novel, extremely halophilic archaeon, D43T, was isolated from traditional salt-fermented seafood in Korea. The cells were Gram-negative-staining and motile. The strain grew at 15–50 °C, 10–30 % (w/v) NaCl and pH 6.0–8.0. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain D43T is affiliated with the family Halobacteriaceae in the domain Archaea and had 95.5 % 16S rRNA gene sequence similarity with Haladaptatus paucihalophilus DX253T. The sequence from strain D43T formed a clade with those from Hap. paucihalophilus regardless of which tree-generating algorithm was used. DNA–DNA hybridization experiments showed 25.8 % relatedness between the isolate and Hap. paucihalophilus KCTC 4006T. Major lipids were phosphatidylglycerol, phosphatidylglycerol phosphate methyl ester and two unidentified glycolipids. The DNA G+C content of the isolate was 56.5 mol%. On the basis of this polyphasic taxonomic study, strain D43T represents a novel species in the genus Haladaptatus, for which the name Haladaptatus cibarius sp. nov. is proposed. The type strain is D43T (=DSM 19505T =JCM 15962T).

Extremely Halophilic Archaeon

An extremely halophilic archaeon, strain D108T, was isolated from a brine sample of Aran-Bidgol salt lake in Iran. The novel strain was cream-pigmented, motile, pleomorphic rod-shaped and required at least 2.5 M NaCl but not MgCl2 for growth. Optimal growth was achieved with 4.3 M NaCl and 0.1 M MgCl2. The optimum pH and temperature for growth were pH 7.5 and 40 °C, respectively, and the strain was able to grow over a pH range of 6.5 to 9.0, and a temperature range of 30 to 50 °C. Phylogenetic analysis based on 16S rRNA gene sequence comparisons revealed that strain D108T clustered with the type strain of the sole species of the genus Halorientalis , Halorientalis regularis TNN28T, with a sequence similarity of 98.8 %. The polar lipid pattern of strain D108T consisted of phosphatidylglycerol, phosphatidylglycerol phosphate methyl ester, one phosphoglycolipid and two glycolipids. The only quinone present was MK-8(II-H2). The DNA G+C content of strain D108T was 62.8 mol%. DNA–DNA hybridization studies (45 % with Halorientalis regularis IBRC-M 10760T), as well as biochemical and physiological characterization, allowed strain D108T to be differentiated from Halorientalis regularis . A novel species of the genus Halorientalis , Halorientalis persicus sp. nov., is therefore proposed to accommodate this strain. The type strain is D108T ( = IBRC-M 10043T = CECT 8375T). An emended description of the genus Halorientalis is also proposed.

Extremely Halophilic Archaeon

An extremely halophilic archaeon, strain RO5-8T, was isolated from a disused marine solar saltern in China. The cells were pleomorphic and flat. In static liquid medium, cells floated to the surface. Strain RO5-8T stained Gram-negative and colonies were pink-pigmented. It was able to grow at 30–50 °C (optimum 40 °C), at 2.6–4.3 M NaCl (optimum 3.1 M NaCl), at 0.03–0.5 M MgCl2 (optimum 0.03 M MgCl2) and at pH 5.5–7.5 (optimum pH 6.0–6.5). Cells lysed in distilled water and the minimal NaCl concentration to prevent cell lysis was 12 % (w/v). The major polar lipids of strain RO5-8T were phosphatidylglycerol, phosphatidylglycerol phosphate methyl ester, phosphatidylglycerol sulfate and one major glycolipid chromatographically identical to the sulfated mannosyl glucosyl diether S-DGD-1. On the basis of 16S rRNA gene sequence analysis, strain RO5-8T was closely related to three strains of Haloplanus natans with similarities of 97.3–97.6 %. The DNA G+C content of strain RO5-8T was 62.1 mol%. The DNA–DNA hybridization value between strain RO5-8T and Haloplanus natans JCM 14081T was 51.6 %. It was concluded that strain RO5-8T represents a novel species of the genus Haloplanus, for which the name Haloplanus vescus sp. nov. is proposed. The type strain is RO5-8T (=CGMCC 1.8712T =JCM 16055T).

Genotypic Characteristics

A novel extremely halophilic archaeon KCY07-B2T was isolated from a salt mine in Kuche county, Xinjiang province, China. Colonies were cream-pigmented and cells were pleomorphic rod-shaped. Strain KCY07-B2T was able to grow at 25–50 °C (optimum 37–45 °C) and pH 6.0–8.0 (optimum 7.0). The strain required at least 1.9 M NaCl for growth. MgCl2 was not required. Cells lysed in distilled water. Polar lipid analysis revealed the presence of phosphatidylglycerol and phosphatidylglycerol phosphate methyl ester, derived from both C20C20 and C20C25 glycerol diethers, together with five glyolipids. The bis-sulfated glycolipid S2-DGD-1 was present. The DNA G+C content was 62.5 mol%. Analysis of the 16S rRNA gene sequence revealed that strain KCY07-B2T was closely related to Halopiger xanaduensis SH-6T and Halopiger aswanensis 56T (95.8 % and 95.5 % similarity, respectively). On the basis of its phenotypic, chemotaxonomic and genotypic characteristics, strain KCY07-B2T is considered to represent a novel species of the genus Halopiger , for which the name Halopiger salifodinae sp. nov. is proposed. The type strain is KCY07-B2T ( = JCM 18547T = CGMCC 1.12284T).

Physiological And Biochemical

A novel, extremely halophilic archaeon B3T was isolated from shrimp-salted seafood. Its morphology, physiology, biochemical features and 16S rRNA gene sequence were characterized. Strain B3T is non-motile, Gram-variable, requires at least 10 % (w/v) NaCl for growth and grows in the ranges of 21–50 °C and pH 6.5–9.0. The DNA G+C content of strain B3T was 63.2 mol%. Phylogenetic analysis based on the 16S rRNA gene sequences indicated that strain B3T belonged to the genus Halalkalicoccus and was phylogenetically closely related to the type strain Halalkalicoccus tibetensis (98.64 %). However, DNA–DNA hybridization experiments showed 7.0 % relatedness between strain B3T and a strain of a reference species of the genus Halalkalicoccus. Combined analysis of 16S rRNA gene sequences, DNA–DNA relatedness data, physiological and biochemical tests indicated that the genotypic and phenotypic characteristics differentiate strain B3T from other Halalkalicoccus species. On the basis of the evidence presented in this report, strain B3T represents a novel species of the genus Halalkalicoccus, for which the name Halalkalicoccus jeotgali. sp. nov. is proposed. The type strain is B3T (=KCTC 4019T=DSM 18796T=JCM 14584T=CECT 7217T).
