Characterization of the Extracellular Polymeric Substances (EPS) of Virgibacillus strains capable of mediating the formation of high Mg-calcite and protodolomite
Aldisi, Zulfa; Zouari, Nabil; Jaoua, Samir; Dittrich, Maria; Al-Kuwari, Hamad; Bontognali, Tomaso... more authors ... less authors ( Qatar University Press , 2020 , Poster)The origin of dolomite -a common carbonate mineral- is the subject of an ongoing debate. It has been proposed that extracellular polymeric substances (EPS) excreted by microbes contain specific organic molecules that ... -
Microbial Mats from the Khor Al-Adaid Sabkha, Qatar: Morphotypes and Association with Authigenic Minerals
Bontognali, Tomaso R.R.; Al Disi, Zulfa Ali; Mckenzie, Judith A.; Strohmenger, Christian J.; Rivers, John M.; Dittrich, Maria; Sadooni, Fadhil; Al-Kuwari, Hamad Al Saad... more authors ... less authors ( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)The sabkhas (i.e., salt flats) of Qatar are among the rare places on Earth where carbonate and sulfate minerals similar to those constituting economically important hydrocarbon reservoirs are still forming today, under the ... -
Systematic laboratory approach to produce Mg-rich carbonates at low temperature
Al Disi, Zulfa Ali; Zouari, Nabil; Attia, Essam; Al-Asali, Mazen; Al Saad Al-Kuwari, Hamad; Sadooni, Fadhil; Dittrich, Maria; Bontognali, Tomaso R.R.... more authors ... less authors ( 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 ... -
Variability of blue carbon storage in arid evaporitic environment of two coastal Sabkhas or mudflats
Al Disi, Zulfa Ali; Naja, Khaled; Rajendran, Sankaran; Elsayed, Hadil; Strakhov, Ivan; Al-Kuwari, Hamad Al Saad; Sadooni, Fadhil; Dittrich, Maria; Al-Khayat, Jassim Abdulla A.... more authors ... less authors ( Nature Research , 2023 , Article)Coastal Sabkhas are mudflats found in arid coastal regions that are located within the supratidal zone when high rates of evaporation lead to high salinity. While evaporitic minerals often accumulate underneath the surface, ...
