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 ...
Evidencing the diversity and needs of adjustment of the nutritional requirements for hydrocarbon-degrading activity of: Pseudomonas aeruginosa adapted to harsh conditions using 2<sup>n</sup> full factorial design
(
Royal Society of Chemistry
, 2017 , Article)
To overcome the partial or complete failure of oil hydrocarbon bioremediation due to weathering processes, occurring in most oil producing and spilling areas, nutritional requirements of the most widely used bacterium, ...
Chemical Characterization and Source Identification of Beached Oil from Two Areas Along the North-Western Coast of Qatar
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
Over the years there have been several reports of oil spills affecting particularly the northern coast of Qatar. In most cases, the source of oil spills is not identified. The spilled oils are very resistant to degradation ...
Mediation of carbonate minerals formation by aerobic bacterial strains isolated from Dohat Faishakh Sabkha in Qatar
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
Carbon dioxide (CO2) is increasingly released to the environment as a result of the extensive use of various industrial facilities. According to the Intergovernmental Panel on Climate Change Report (2015), cumulative ...
Characterization of Commercial Reverse Osmosis and Nanofiltration Membranes for Membrane Fouling
(
Hamad bin Khalifa University Press (HBKU Press)
, 2018 , Conference Paper)
Membrane Filtration technique is being accepted worldwide as an environment friendly and energy efficient technique in Desalination Industry as compared to Thermal Desalination techniques. However, the performance of ...
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 ...
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
(
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 ...
Shear and Tensile Strength Measurements of CaCO 3 Cemented Bonds between Glass Beads Treated by Microbially Induced Carbonate Precipitation
(
American Society of Civil Engineers (ASCE)
, 2023 , Article)
The particle-scale shear and tensile strength measurements of microbial-induced calcite precipitation (MICP) treatment have been investigated in this paper. Glass beads were used to represent sand particles. Three ...
Microbially induced calcite precipitation in calcareous soils by endogenous Bacillus cereus, at high pH and harsh weather
(
Elsevier
, 2020 , Article)
Microbially induced calcite precipitation (MICP) improves the physical properties of soils by increasing the solid content, decreasing the pore sizes and improving the rigidity of the particle-to-particle contact ending ...
