Influence of temperature, salinity and Mg:Ca ratio on microbially-mediated formation of Mg-rich carbonates by Virgibacillus strains isolated from a sabkha environment.
Al Disi, Zulfa Ali; Bontognali, Tomaso R R; Jaoua, Samir; Attia, Essam; Al-Kuwari, Hamad Al Saad; Zouari, Nabil... more authors ... less authors ( Nature Research , 2019 , Article)Studies have demonstrated that microbes facilitate the incorporation of Mg into carbonate minerals, leading to the formation of potential dolomite precursors. Most microbes that are capable of mediating Mg-rich carbonates ... -
Mapping of aeolian deposits of an industrial site in the arid region using the TIR bands of ASTER and study of physicochemical characters and stabilization of sand erosion
Sankaran, Rajendran; Zouari, Nabil; Sadooni, Fadhil N.; Al Disi, Zulfa Ali; Al-Jabri, Abdulaziz; Al-Kuwari, Hamad Al Saad... more authors ... less authors ( Taylor and Francis Group , 2022 , Article)This study describes the spectral emissive character of silicate and carbonate minerals of aeolian deposits and maps the deposits and sand encroachments that occurred in and around the site 5/6 of Qatar Fertilizer Company ... -
Mechanistic insights into the remediation of bromide ions from desalinated water using roasted date pits
Al-Ghouti, Mohammad A.; Al Disi, Zulfa Ali; Al-Kaabi, Nasser; Khraisheh, Majeda ( Elsevier B.V. , 2017 , Article)Bromide ions (Br−) are associated with toxic by-products that might be produced during the disinfection of drinking water. The removal of Br− from water using roasted date pits (RODPs) and activated carbon was investigated. ... -
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 ...
