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 ... -

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 ...
