Immobilization of heavy metals by microbially induced carbonate precipitation using hydrocarbon-degrading ureolytic bacteria
Zulfa Al, Disi; Attia, Essam; Ahmad, Mohammad I.; Zouari, Nabil ( Elsevier , 2022 , Article)Crude oil contamination introduces multiple threats to human health and the environment, most of which are from toxic heavy metals. Heavy metals cause significant threats because of their persistence, toxicity, and ... -
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 ... -
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 ...
