“…to accommodate isolates from thalassohaline and athalassohaline environments with the type species Haloarcula vallismortis [2]. The genus comprises ten species at present: Haloarcula amylolytica , Haloarcula argentinensis , Haloarcula hispanica , Haloarcula japonica , Haloarcula marismortui , Haloarcula quadrata , Haloarcula salaria , Haloarcula tradensis , Haloarcula vallismortis and Haloarcula sebkhae [3, 4]. They are red- or pink-pigmented extremely halophilic pleomorphic rods with shapes ranging from almost regular rods to triangular and irregular shapes requiring at least 2.0 M NaCl for growth [4–6].…”

A mannan-degrading halophilic archaeal strain, MD130-1T, was isolated from a commercial salt sample. Cells were motile, rod-shaped, and stained Gram-negative. Colonies were pink pigmented. Strain MD130-1T was able to grow at 1.5–4.6 M NaCl (optimum, 3.6 M) at pH 6.0–8.0 (optimum, pH 7.0) and at 25–50 °C (optimum, 40 °C). The DNA G+C content was 62.1 mol% (genome). The orthologous 16S rRNA gene sequence showed the highest similarity (99.4 %) to those of Haloarcula japonica JCM 7785T and Haloarcula hispanica JCM 8911T. The values of genome relatedness between strain MD130-1T and Haloarcula species were 84.33–85.96 % in ANIb and 30.4–32.9 % using GGDC formula 2. The polar lipids of strain MD130-1T were phosphatidylglycerol, phosphatidylglycerol phosphate methyl ester and triglycosyl diether-2. Based on the results of phenotypic and phylogenetic analyses, the strain represents a new species of the genus Haloarcula , for which the name Haloarcula mannanilytica sp. nov. is proposed. The type strain is MD130-1T (=JCM 33835T=KCTC 4287T) isolated from commercial salt made in Ishikawa prefecture, Japan.

Ha.lo.glo'mus. Gr. masc. n. hals, halos salt; L. neut. n. glomus a ball; N.L. neut. n. Haloglomus , a salt ball. Euryarchaeota / Halobacteria / Halobacteriales / Haloarculaceae / Haloglomus The genus Haloglomus is classified within the family Haloarculaceae, order Halobacteriales , and class Halobacteria . The cells are Gram‐stain‐negative, nonmotile, and pleomorphic, curved to irregular shaped. Colonies are red pigmented. Strictly aerobic. Extremely halophilic. Optimal growth at 5.1 M NaCl, pH 7.5, and 37°C. Catalase‐positive and oxidase‐negative. Acid is produced from d ‐glucose and other carbohydrates. Polar lipids include phosphatidylglycerol (PG), phosphatidylglycerol phosphate methyl ester (PGP‐Me), phosphatidylglycerol sulfate (PGS), and one glycolipid chromatographically identical to sulfated mannosyl glucosyl diether (S‐DGD‐1). Currently, the genus includes a single species, Haloglomus irregulare (type species of the genus), that was isolated from a marine saltern. DNA G + C content (mol%) : 68.0 (genome). Type species : Haloglomus irregulare Durán‐Viseras et al. 2020, VL193.

Ha.lo.seg'nis. Gr. masc. n. hals, halos , salt; L. masc. adj. segnis , slow; N.L. masc. n. Halosegnis , a slow salt [growing] organism. Euryarchaeota / Halobacteria / Halobacteriales / Haloarculaceae / Halosegnis The genus Halosegnis is classified within the family Haloarculaceae , order Halobacteriales , and to the class Halobacteria . The cells are Gram‐stain‐negative, nonmotile rods, producing red‐ to light red‐pigmented colonies. Strictly aerobic. Extremely halophilic. Optimal growth at 20–25% (w/v) NaCl, at pH 7.5, and 37°C. Heterotrophic. Catalase‐positive but oxidase‐negative. The major polar lipids include biphosphatidylglycerol (BPG), phosphatidylglycerol (PG), phosphatidylglycerol phosphate methyl ester (PGP‐Me), phosphatidylglycerol sulfate (PGS), one glycolipid chromatographically identical to sulfated mannosyl glucosyl diether (S‐DGD‐1), sulfated triglycosyl diphytanyl archaeol ester linked to phosphatidic acid (S‐TGD‐1‐PA), and sulfated tetraglycosyl diether (S‐TeGD). Currently, the genus includes two species: Halosegnis rubeus (type species of the genus) and Halosegnis longus . Both species were isolated from marine salterns, but they are widely distributed in hypersaline aquatic habitats, especially at intermediate salinities. DNA G + C content (mol%): 64.7–66.0 (genome). Type species: Halosegnis rubeus Durán‐Viseras et al. 2021, VL203.
