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 ... -
Isolation and Screening of Hydrocarbon Degrading Bacterial Strains for Bioremediation of Petroleum Pollution in Qatar
Al Disi, Zulfa Ali (2013 , Master Thesis)Pollution, due to activities related to the oil industry, represents a serious threat to the natural environment. The application of biotechnological methods provides much safer and sustainable alternatives for bioremediation ... -
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 ... -
Microbially influenced formation of anhydrite at low temperature
Al Disi, Zulfa Ali; Sadooni, Fadhil; Al-Kuwari, Hamad Al Saad; Bontognali, Tomaso R.R. ( Elsevier B.V. , 2023 , Article)Calcium sulfate minerals are abundant in nature – on Earth and on Mars – and important in several fields of material sciences. With respect to gypsum and bassanite, anhydrite represents the anhydrous crystalline phase in ... -
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, ...
