An overview of brine management: Emerging desalination technologies, life cycle assessment, and metal recovery methodologies
(
Elsevier
, 2021 , Article Review)
This study examines which management methods are the most recent and advanced in managing rejected brine generated from desalination plants. It also provides up-to-date information regarding the most adequate technologies ...
Characterization of the Extracellular Polymeric Substances (EPS) of Virgibacillus strains capable of mediating the formation of high Mg-calcite and protodolomite
(
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 ...
The use of Principle Component Analysis and MALDI-TOF MS for the differentiation of mineral forming Virgibacillus and Bacillus species isolated from Sabkhas.
(
Qatar University Press
, 2020 , Poster)
Occurrence of mineral forming and other bacteria in mats is well demonstrated. However, their high diversity shown by ribotyping was not explained, although could explain the diversity of formed minerals. Common biomarkers ...
Development of Polymer Modified Graphene Oxide Nanocomposite Membranes to Reduce both Scaling and Biofouling
(
Qatar University Press
, 2020 , Poster)
In seawater reverse osmosis (SWRO), membrane scaling is one of the major issues affecting its widespread application in the desalination industry. In this research, the effect of concentration of calcium and sulfate ions ...
Investigating the concomitant removal of hydrocarbons and heavy metals by highly adapted Bacillus and Pseudomonas strains
(
Qatar University Press
, 2021 , Poster)
This study investigates the concomitant removal of hydrocarbons and heavy metals by highly adapted Bacillus and Pseudomonas strains. In regions characterized by harsh conditions such as Qatar, the weathering processes would ...
Bio self-healing concrete using MICP by an indigenous Bacillus cereus strain isolated from Qatari soil
(
Elsevier
, 2022 , Article)
In this study, the self-healing process in concrete through microbial-induced calcium carbonate precipitation (MICP) performed by an adapted indigenous strain of Bacillus cereus isolated from soils in Qatar was investigated. ...
Systematic laboratory approach to produce Mg-rich carbonates at low temperature
(
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 ...
Investigating the simultaneous removal of hydrocarbons and heavy metals by highly adapted Bacillus and Pseudomonas strains
(
Elsevier
, 2022 , Article)
The status, content and availability of heavy metals and hydrocarbons are highly affected by weathering processes – particularly – in areas characterized by harsh conditions. Their concomitant removal by highly adapted ...
Immobilization of heavy metals by microbially induced carbonate precipitation using hydrocarbon-degrading ureolytic bacteria
(
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 ...
Proteomic analysis of T. qataranse exposed to lead (Pb) stress reveal new proteins with potential roles in Pb tolerance and detoxification mechanism
(
Frontiers Media
, 2022 , Article)
Soil lead (Pb) contamination is one of the environmental problems facing the modern world. Sources of Pb in soil include industrial activities such as mining and smelting processes, agricultural activities such as application ...
