Evidencing the role of carbonic anhydrase in the formation of carbonate minerals by bacterial strains isolated from extreme environments in Qatar
( Elsevier , 2022 , Article)Calcium carbonate, one of the most abundant minerals in the geological records is considered as primary source of the carbon reservoir. The role of microorganisms in the biotic precipitation of calcium carbonate has been ... -
The importance of microbial mats for dolomite formation in the Dohat Faishakh sabkha, Qatar
( Springer Verlag , 2015 , Article)The Dohat Faishakh sabkha in Qatar is one of the rare modern environments where it is possible to study the formation of dolomite, a mineral whose origin has been long debated. In previous studies, dolomite formation in ... -
Insights into the interaction between mineral formation and heavy metals immobilization, mediated by Virgibacillus exopolymeric substances
( Elsevier , 2024 , Article)Heavy metal pollution poses significant risks to both the environment and human health due to their toxicity, long residence times, and their ability to bioaccumulate and bio magnify across the food chain. To address this ... -
Medicinal properties of Qatari wetland plants: A review
( AkiNik Publications , 2024 , Article)For over 60,000 years, human dependence on herbal remedies has been a cornerstone of traditional medicine. However, recent times have witnessed escalating concerns about the sustainability of these practices, especially ... -
Microbial community composition and dolomite formation in the hypersaline microbial mats of the Khor Al-Adaid sabkhas, Qatar
( Springer Tokyo , 2019 , Article)The Khor Al-Adaid sabkha in Qatar is among the rare extreme environments on Earth where it is possible to study the formation of dolomite-a carbonate mineral whose origin remains unclear and has been hypothetically linked ... -
Microbial dolomites from carbonate-evaporite sediments of the coastal sabkha of Abu Dhabi and their exploration implications
( wiley online library , 2010 , Article)Detailed petrographic studies of Recent dolomites from the coastal sabkha of Abu Dhabi using SEM and Energy Dispersive X-ray (EDX) analyses indicate that most of the dolomite started to form in " micro-niches" (i.e. small ... -
Raman Spectroscopic and Microbial Study of Biofilms Hosted Gypsum Deposits in the Hypersaline Wetlands: Astrobiological Perspective
( Mary Ann Liebert Inc. , 2023 , Article)Gypsum (CaSO4.2H2O) has been identified at the surface of Mars, by both orbiters and rovers. Because gypsum mostly forms in the presence of liquid water as an essential element for sustaining microbial life and has a low ... -
Raman spectroscopy of the Dukhan sabkha: identification of geological and biogeological molecules in an extreme environment
( The Royal Society , 2010 , Article)The characterization of minerals and biogeological deposits in a terrestrial Arabian sabkha has a direct relevance for the exploration of Mars since the discovery by the NASA rovers Spirit and Opportunity of evaporate ... -
Systematic laboratory approach to produce Mg-rich carbonates at low temperature
( Royal Society of Chemistry , 2021 , Article)Dolomite is a common Mg-rich carbonate in the geological record, but the mechanism of its formation remains unclear. At low temperature, the incorporation of magnesium ions into the carbonate minerals necessary to form ...
