Summary: The study used FISH and PCR to determine prokaryotic diversity in Urmia Salt Lake. It found that the prokaryote cell populations were more diverse and abundant than expected in this hypersaline environment, with bacteria forming the metabolically active part of the microbial population. Molecular approaches revealed different aspects of the microbiota in this extreme environment.

Summary: The Persian Gulf, with 48% of the world's oil reserves, is continuously exposed to natural oil seepage. Studies have shown that chronic exposure to trace amounts of pollution in the Gulf promotes the growth of oil-degrading microbes, leading to shifts in the microbial community composition in polluted areas. Hydrocarbon type, exposure time, and sediment depth are identified as the main factors determining microbial response to pollution in oil-polluted marine samples.

Summary: Lake Urmia in Iran is a hypersaline environment with a salinity of about 27%. Metagenomic analysis revealed that the microbial community in the lake is dominated by Haloferacaceae family (69.8%), mainly Haloquadratum (59.3%) and Halonotius (9.1%). The bacterial community is mainly composed of Salinibacter ruber (23.3%). Genomic variation analysis showed a high level of SNVs and insertions in Lake Urmia's community, possibly due to transformation caused by the extreme conditions and high ionic concentrations.

Summary: This study investigated the removal of phenol using Small Bioreactor Chambers and CaO2 nanoparticles in continuous-flow sand-packed columns. The results showed that simultaneous biostimulation and bioaugmentation could completely eliminate phenol within 42 days, while natural bioremediation columns still had 80.2% remaining at the end of the experiment. CaO2 injection decreased microbial diversity, with order-level groups such as Rhodobacterales and Xanthomonadales dominating in biostimulation columns. Long-term exposure to phenol shifted the microbial population towards heterotrophic members with the potential for phenol and hydrocarbon degradation.

Summary: Selenium oxyanions are released into environments from various activities and are present in wastewater in many locations worldwide. Excessive amounts of selenium have negative impacts on living organisms. Halophilic and halotolerant microorganisms were used for selenium oxyanion remediation in wastewater containing salt. Factors such as aeration, carbon sources, competitive electron acceptors, and reductase inhibitors were investigated for their effects on SeO32- removal. The study also explored the remediation of SeO32- in agricultural effluents containing NO3-. The results showed that aerobic conditions with succinate as a carbon source were most effective for SeO32- removal. Certain ions, such as WO42- and TeO32-, decreased the removal percentage, while SO42- and PO43- had minimal interference. NO3- had an adverse effect on SeO32- biotransformation. Consortia of halophilic/halotolerant bacteria and yeasts were able to reduce SeO32- in synthetic agricultural wastewater by 45-53% within 120 hours. This study suggests that these consortia could be used for the bioremediation of selenium-contaminated drainage water.

Summary: In recent years, there has been growing interest in the anticancer properties of metabolites from halophilic microorganisms. This study investigated the effects of supernatant metabolites from 29 halophilic bacterial strains on the stem cell-like properties of six human cancer cell lines. The metabolites from Salinivenus iranica demonstrated the most potent cytotoxic effect on breast cancer cell lines, with no effect on normal cells. The purified cytotoxic molecule, a phenol amine, downregulated the expression of the pluripotency gene SOX-2 in breast cancer cells.
