BIOTREATMENT OF GTL PROCESS WATER AND PESTICIDES CONTAMINATED WATER USING PSEUDOMONAS AERUGINOSA: A COMPARATIVE STUDY
(2023 , Master Thesis)Over 40% of the world's population suffers from water scarcity, a problem that is expected to get worse because of global warming and desertification. Therefore, the mean of treatment and reuse of wastewater has become ... -
Can biodegradable plastics solve plastic solid waste accumulation ?
( Elsevier , 2018 , Book chapter)Polymers are fast becoming a serious environmental hazard, and are normally disposed of through landfilling, recycling, and incineration. Landfill sites are becoming increasingly scarce, and incineration contributes to air ... -
Competitive interference during the biodegradation of cresols
( Center for Environmental and Energy Research and Studies , 2018 , Article)Phenol and its methylated derivatives, cresol isomers, are hazardous pollutants that are commonly present in various industrial effluents and known to have detrimental effect on aquatic life as well as human health, due ... -
Development of biopolymeric hybrid scaffold-based on aac/go/nhap/tio2 nanocomposite for bone tissue engineering: In-vitro analysis
( MDPI AG , 2021 , Article)Bone tissue engineering is an advanced field for treatment of fractured bones to re-store/regulate biological functions. Biopolymeric/bioceramic-based hybrid nanocomposite scaffolds are potential biomaterials for bone ... -
Experimental analysis and modeling of the methane degradation in a three stage biofilter using composted sawdust as packing media
( J. Environ. Manage. , 2021 , Article)Methane gas is a very effective greenhouse gas and the second-largest contributor to global warming. Biofiltration is an effective technology that uses microorganisms to degrade the pollutant by oxidizing it. In this work, ... -
Identification and overcome of limitations of weathered oil hydrocarbons bioremediation by an adapted Bacillus sorensis strain
( Academic Press , 2019 , Article)Because of the high production of oil and gas in Qatar, the likelihood of oil spill occurrence is most probably susceptible to happen. Contaminated soil treatment is very expensive. Cost effective mechanisms are investigated ... -
Immobilization of microbial cells for the biotreatment of wastewater: A review
( Springer Verlag , 2019 , Article Review)Industrial wastewater often contains different complex impurities that are hazardous to the environment and human health, making wastewater treatment a necessity prior to its disposal. This review focuses on cell immobilization ... -
Influence of Water Table Fluctuation on Natural Source Zone Depletion in Hydrocarbon Contaminated Subsurface Environments
( Qatar Univesrity Press , 2020 , Conference Paper)Most of the prediction theories regarding dissolution of organic contaminants in the subsurface systems have been proposed based on the static water conditions and the influence of water fluctuations on mass removal requires ... -
Investigation on the effect of several parameters involved in the biodegradation of polyethylene (PE) and low-density polyethylene (LDPE) under various seawater environments
( Elsevier , 2024 , Article)This work investigates the biodegradation of polyethylene (PE) and low-density polyethylene (LDPE) and the leaching of their harmful additives. Micro/macro-plastics of both types were subjected to different laboratory-controlled ... -
Isolation and characterization of a newly naphthalene degrading Halomonas pacifica, strain Cnaph3: biodegradation and biosurfactant production studies
