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: The present study investigated halophilic and halotolerant fungi from solar salterns in Thailand, and characterized them using morphological and molecular techniques. The study examined their ability to produce extracellular enzymes, secondary metabolites, and mycoviruses. It was found that some strains exhibited halophilic or halotolerant properties, and the fungal isolates were classified into different genera. The majority of the active isolates were identified as Aspergillus and Penicillium species, and their crude extracts showed inhibitory effects on bacteria and pathogenic fungi. Research on fungi from saline environments can provide valuable insights into the biotechnological and industrial potential of these strains.

Summary: This study quantitatively analyzed the presence of four compatible solutes in forty-five halophilic/halotolerant bacterial isolates, and identified several bacterial isolates producing ectoine and hydroxyectoine. The findings of this study provide a basis for the large-scale production of ectoine and hydroxyectoine in the future.

Summary: Lignin is an abundant compound in nature and plays a vital role in the carbon cycle. This study identified enzymes involved in the degradation of lignin-derived compounds in a lignin-degrading fungus. The enzymes showed exceptional oxidative potential and broad substrate specificity, making them a promising candidate for biotechnological applications.

Summary: In this study, an IBU-mineralizing consortium C6 was obtained and two IBU degraders, Streptomyces sp. D218 and Pseudomonas sp. M20, were isolated. The results suggest that the degradation of IBU in the consortia C1 and C6 may be mainly mediated by key players of Streptomyces and Pseudomonas, respectively.

Summary: A halophilic bacterium, designated as Modicisalibacter sp. strain Wilcox, was isolated from produced water and demonstrated the ability to degrade aromatic and aliphatic hydrocarbons at high salinity. Genome analysis revealed a repertoire of hydrocarbon degradation genes as well as heavy metal resistance genes. The strain may be useful for the remediation of produced waters due to its versatile degradation capabilities and tolerance to extreme environmental conditions.

Summary: Hyper-saline evaporitic sandflats known as Sabkhas in the Gulf states are prone to oil contamination. Bioaugmentation using indigenous microorganisms can help ameliorate oil pollution in Sabkha environments. This study conducted a cross-bioaugmentation process using enriched inocula of hydrocarbonoclastic bacteria to assess oil bioremediation in artificially oil-contaminated soils from two Sabkha locations in Kuwait. The researchers found that bioaugmentation significantly enhanced oil degradation at only one location, and the dominant strain in the enriched inocula failed to colonize the bioaugmented soils. The study also revealed the oil biodegradation potential of sixteen hydrocarbonoclastic isolates under different salinity conditions.

Summary: The halotolerant bacterial consortium (LF) was found to effectively degrade DOP under optimal conditions, with a high removal efficiency. The biodegradation pathway for DOP by LF was proposed based on GC-MS analysis. LF shows potential for remediation of DOP-contaminated environments and can degrade DOP in soil, indicating promising application prospects.

Summary: In this study, a bacterial consortium C10 capable of degrading different alkyl chain lengths of phthalate plasticizers (DEHP, dibutyl phthalate, diethyl phthalate, and dimethyl phthalate) was enriched and identified in marine sediment. The major bacterial genera during degradation of the phthalate plasticizers were Gluta-micibacter, Ochrobactrum, Pseudomonas, Bacillus, Stenotrophomonas, and Methylophaga. Through a network-based approach, it was predicted that Bacillus, Stenotrophomonas, and Microbacterium cooperatively interacted as the main degraders of phthalate plasticizers. Twenty isolates belonging to different bacterial genera were obtained through selective isolation techniques, and the best DEHP-degraders were identified as Steno-trophomonas acidaminiphila OR13, Microbacterium esteraromaticum OR16, Sporosarcina sp. OR19, and Cytobacillus firmus OR20. This study provides insights into the PAE-degradation capabilities of marine sediment bacteria and offers a simple approach for the prediction and isolation of potential pollutant degraders from complex bacterial communities.

Summary: This study investigated the growth and degradation potential of Stenotrophomonas maltophilia KB2 and Pseudomonas moorei KB4 strains towards phenol under suboptimal conditions. The results showed that the degradation time of phenol by both strains varied under different temperatures, pH levels, and salinity, and this degradation ability was related to the activity of catechol dioxygenases and membrane permeability.

Summary: The marine ecosystem provides solutions for food, shelter, and pharmaceutical problems, and it plays a crucial role in the country's economy, particularly in tourism. However, the Gulf of Kachchh, known for its high tides and coral reefs, has been less explored for its antibiotic activity due to coral bleaching and diseases. In this study, bacterial strains isolated from the coral Porites lutea showed antibiotic activity against various bacterial strains. The extracted antibiotic compound was identified as 4-[(2E)-4-hydroxypent-2-en-1-yl]-5,6-dihydro-2H-pyran-2-one and was found to have potential as a drug lead with low toxicity and good drug-likeness. The study also investigated the production of Poly Hydroxy Butarate (PHB) by the isolated bacterial strain.
