A halophilic archaeal strain, designated F16-60T, was isolated from Isla Cristina marine saltern in Huelva, Spain. Cells were pleomorphic, irregular, non-motile, and Gram-stain-negative. It produced red-pigmented colonies on agar plates. Strain F16-60T was extremely halophilic (optimum at 30% (w/v) NaCl) and neutrophilic (optimum pH 7.5)....

A halophilic archaeon, strain F20-122T, was isolated from a marine saltern of Isla Bacuta (Huelva, Spain). Cells were Gram-stain-negative, aerobic, and coccoid in morphology. It grew at 25-50 °C (optimum 37 °C), pH 6.5-9.0 (optimum pH 8.0), and 10-30% (w/v) total salts (optimum 25% salts). The phylogenetic analyses based on the 16S rRNA and...

Metagenomic studies on prokaryotic diversity of hypersaline soils from the Odiel saltmarshes, South-west Spain, revealed a high proportion of genomic sequences not related to previously cultivated taxa, that might be related to haloarchaea with a high environmental and nutritional flexibility. In this study, we used a culturomics approach in...

An extremely halophilic archaeon, strain F13-25T, was isolated from a marine saltern located in Isla Cristina, Huelva, on the south-west coast of Spain. The novel strain had pink-pigmented, non-motile, coccoid cells. Optimal growth was achieved at 25 % (w/v) NaCl, pH 7.5 and 37 °C. Strain F13-25T possessed two heterogeneous 16S rRNA genes (rrnA...

A yellow-pigmented, motile, Gram-stain-negative, moderately halophilic and strictly aerobic bacterium, designated BA42AL-1T, was isolated from water of a saltern of Santa Pola, Alicante, Spain. Strain BA42AL-1T grew in media containing 5–20% (w/v) salts (optimum 7.5% salts). It grew between pH 6.0 and 9.0 (optimally at pH 7.5) and at 15–45°C...

A halophilic archaeon, strain F13-13T , was isolated from a marine saltern located in Isla Cristina, Huelva, on the southwest coast of Spain. It was a Gram-stain-negative, motile and aerobic haloarchaeon. It grew at 28–50 C (optimum, 37 C), pH 6.0–8.5 (pH 7.5) and in 15–30 % (w/v) total salts (25 %). Phylogenetic analyses based on the 16S...

A comparative taxonomic study of Spiribacter and Halopeptonella species was carried out using a phylogenomic approach based on comparison of the core genome, orthologous average nucleotide identity (OrthoANIu), Genome-to-Genome Distance Calculator (GGDC) and average amino acid identity (AAI). Phylogenomic analysis based on 976 core translated...

Aim This study aimed to isolate moderately halophilic bacteria from salted goat skins, to characterize these microorganisms and to determine their industrially important enzymes such as amylase, catalase, oxidase, caseinase, cellulase, DNase, lipase, lecithinase, protease, pullulanase, urease, phospholipase, xylanase and...

A moderately halophilic bacterium designated strain M6-53T was isolated from water of a pond from a marine saltern located in Huelva, south-west Spain. Cells of the strain were Gram-stain-negative, strictly aerobic, motile, slightly curved rods, able to grow in media containing 5–25 % (w/v) NaCl (optimal growth at 10 %, w/v), at temperatures...

Hypersaline soils are extreme environments that have received little attention until the last few years. Their halophilic prokaryotic population seems to be more diverse than those of well-known aquatic systems. Among those inhabitants, representatives of the family Balneolaceae (phylum Balneolota) have been described to be abundant, but very...

Hypersaline soils are a source of prokaryotic diversity that has been overlooked until very recently. The phylum Bacillota, which includes the genus Aquibacillus, is one of the 26 phyla that inhabit the heavy metal contaminated soils of the Odiel Saltmarshers Natural Area (Southwest Spain), according to previous research. In this study, we...
