Abstract:

Solar salterns are excellent model ecosystems for studying virus-microbial interactions because of their low microbial diversity, environmental stability, and high viral density. By using the power of CRISPR spacers to link viruses to their prokaryotic hosts, we explored virus-host interactions in geographically diverse salterns. Using taxonomic profiling, we identified hosts such as archaeal Haloquadratum, Halorubrum, and Haloarcula and bacterial Salinibacter, and we found that community composition related to not only salinity but also local environmental dynamics.

Prokaryotic communities and physico-chemical characteristics of 30 brine samples from the thalassohaline Tuz Lake (Salt Lake), Deep Zone, Kayacik, Kaldirim, and Yavsan salterns (Turkey) were analyzed using 16S rRNA amplicon sequencing and standard methods, respectively. Archaea (98.41% of reads) was found to dominate in these habitats in contrast to the domain Bacteria (1.38% of reads). Representatives of the phylum Euryarchaeota were detected as the most predominant, while 59.48% and 1.32% of reads, respectively, were assigned to 18 archaeal genera, 19 bacterial genera, 10 archaeal genera, an

Australian isolates of Haloquadratum walsbyi, a square-shaped haloarchaeon, often harbor small cryptic plasmids of the pL6-family, approximately 6 kb in size, and five examples have been previously described. These plasmids exhibit a highly conserved gene arrangement and encode replicases similar to those of betapleolipoviruses. To assess their global distribution and recover more examples for analysis, fifteen additional plasmids were reconstructed from the metagenomes of seven hypersaline sites across four countries: Argentina, Australia, Puerto Rico, and Spain.

The solar salterns located in the Odiel marshlands, in southwest Spain, are an excellent example of a hypersaline environment inhabited by microbial populations specialized in thriving under conditions of high salinity, which remains poorly explored. Traditional culture-dependent taxonomic studies have usually under-estimated the biodiversity in saline environments due to the difficulties that many of these species have to grow at laboratory conditions. Here we compare two molecular methods to profile the microbial population present in the Odiel saltern hypersaline water ponds (33% salinity).

Protein splicing is a self‐catalyzed, post‐translational process in which an intervening polypeptide (intein) catalyzes its own removal from the flanking polypeptides (exteins), as well as the ligation of the exteins. We are interested in the splicing of two inteins interrupting the cdc21 protein from Haloquadratum walsbyi (Hwa). Hwa is a halophilic archaeon. Because of this, we hypothesized that protein splicing would be salt dependent. The first intein, Cdc21a, does not splice on overexpression in E. coli, but can be induced to splice in vitro on incubation with 2.5 M sodium chloride at 28°C

Previous work in the lab demonstrated that splicing of the Hsa DNA Polymerase II (Polll) intein is salt‐dependent. We attempted to compare the homologous PolII‐a intein in Hwa.

Abstract:

AbstractLake Urmia located in Iran is a hypersaline environment with a salinity of about 27% (w/v). Metagenomic analyses of water samples collected from six locations in the lake exhibited a microbial community dominated by representatives of the family Haloferacaceae (69.8%), mainly those affiliated to only two genera, Haloquadratum (59.3%) and Halonotius (9.1%). Similar to other hypersaline lakes, the bacterial community was dominated by Salinibacter ruber (23.3%). Genomic variation analysis by inspecting single nucleotide variations (SNVs) and insertions/deletions (INDELs) exhibited a high

Abstract:

AbstractOur understanding of the microbial diversity inhabiting hypersaline environments, here defined as containing >100–150 g/L salts, has greatly increased in the past five years. Halophiles are found in each of the three domains of life. Many novel types have been cultivated, and metagenomics and other cultivation-independent approaches have revealed the existence of many previously unrecognized lineages. Syntrophic interactions between different phylogenetic lineages have been discovered, such as the symbiosis between members of the archaeal class Halobacteria and the ‘Candidatus Nanoh

Abstract:

Protein splicing is a post‐translational modification by which a segment of protein, known as an intein, self‐catalyzes its excision from the flanking protein while simultaneously ligating the two flanking exteins. Inteins can be found in many types of archaea, such as halophiles, which specifically thrive in environments with high salt concentrations. The lab previously reported that the Halobacterium salinarum (Hsa) DNA polymerase II (Pol II) intein promotes conditional protein splicing at high concentrations of sodium chloride. To study the structure of the intein, we attempted to find cond

Abstract:

ABSTRACTThe salt ponds of Trapani, Sicily, represent an extreme and under‐explored ecosystem characterised by varying salinity gradients and environmental conditions. These ponds, integral to traditional salt extraction, include cold, driving, hot and crystallizer ponds, each hosting diverse microbial communities. This study aimed to explore the biological and physical–chemical diversity of 11 ponds during the salt production season in Trapani. We conducted comprehensive physical–chemical characterizations, including measurements of pH, conductivity, viscosity, density, organic carbon and ion

Abstract:

Abstract High-throughput RNA-seq enables the analysis of gene expression in complex, culture-independent microbial communities. In this study, we used this approach to explore the microbial adaptation to salinity changes in hypersaline environments using samples collected from the Santa Pola ponds (Alicante, Spain). Two metatranscriptomic experiments were conducted: (i) salt concentration from 20 to 30%, mimicking summer evaporation, and (ii) dilution from 30 to 25%, simulating rainfall. As a result, these two experiments revealed significant differences in the gene expression of several metab

Abstract:

Protein splicing is a post‐translational process that results in the removal of an intervening polypeptide, the intein, and the ligation of the flanking C‐ and N‐terminal polypeptides, the exteins, to form a mature protein. Although protein splicing occurs without the need for any cofactor, chaperone or energy source, the proper conformation of the active site may be influenced by environmental cues. Undergraduates in our lab have carried out experiments to study the structure and mechanism of inteins from halophiles and deep‐sea thermophiles. We have shown that an intein from Halobacterium sa

Abstract:

Abstract To understand how extreme halophiles respond to recurrent disturbances, we challenged the communities thriving in salt-saturated (~36% salts) ~230 L brine mesocosms to repeated dilutions down to 13% (D13 mesocosm) or 20% (D20 mesocosm) salts each time mesocosms reached salt saturation due to evaporation (for 10 and 17 cycles, respectively) over 813 days. Depending on the magnitude of dilution, the most prevalent species, Haloquadratum walsbyi and Salinibacter ruber, either increased in dominance by replacing less competitive populations (for D20, moderate stress conditions), or severe
