Summary: This study aimed to identify and characterize novel siderophore-producing organisms from hypersaline, alkaline surface waters. Two halophilic strains designated ATCHA(T) and ATCH28(T) were isolated, and their affiliation with the genus Halomonas was determined. Both strains were found to secrete siderophores based on the CAS assay and genomic analysis. Strain ATCH28(T) was found to produce a non-amphiphilic siderophore called desferrioxamine E (DFOE), and the quantity of DFOE secretion could be increased through media optimization. These findings contribute to the understanding of siderophore production in halophilic microorganisms and propose two new species of the genus Halomonas.

Summary: Five novel halophilic archaeal strains were isolated from coastal saline sediments and sea salt in China. They demonstrated typical morphology and growth characteristics and showed high similarities with existing species. However, based on genetic and phylogenetic analyses, it is confirmed that these strains represent five new species. This is the first report of a novel haloarchaeon isolated from a marine intertidal zone.

Summary: Two Gram- stain- negative strains, SYSU D00286(T) and SYSU D00782, were isolated from a sand sample collected from the Kumtag Desert in Xinjiang, north-west China. They were identified as a new species of the genus Rubellimicrobium and named Rubellimicrobium arenae sp. nov. based on their phylogenetic, phenotypic and chemotaxonomical features.

Summary: A new Thalassococcus species, T. arenae sp. nov., was isolated from a sea sand sample collected from the Republic of Korea. This strain showed optimal growth at temperature 30 degrees C, pH 7.5, and NaCl concentration of 1.0%. Phylogenetic analysis based on 16S rRNA gene sequences revealed its similarity to other Thalassococcus species.
