Thermal modeling and optimization of microalgal biomass production in the harsh desert conditions of State of Qatar
( Elsevier B.V. , 2019 , Article)Microalgal culture in solar conditions raises several challenges, especially in the harsh desert areas of the Middle East where microalgal culture is a valuable candidate for biomass production on non-arable land. Here we ... -
Hydrothermal liquefaction of marine microalgae biomass using co-solvents
( Elsevier B.V. , 2019 , Article)Hydrothermal liquefaction (HTL) of microalgae biomass is a promising conversion technology in which wet biomass is treated under high temperature (280–350 °C) and pressure (5–21 MPa), and the associated water in the wet ... -
Microalgal bioremediation of petroleum-derived low salinity and low pH produced water
( Springer Netherlands , 2019 , Article)Due to the presence of toxic organic compounds and heavy metals, it is essential to treat the produced water before reuse or discharge to the environment. In this study, produced water sample was collected from a local ... -
Assessment of the algae-based biofertilizer influence on date palm (Phoenix dactylifera L.) cultivation
( Springer Netherlands , 2019 , Article)Date palm (Phoenix dactylifera L.) is the main fruit crop found in the arid and semi-arid regions of the world. It naturally adapts to the adverse environments of extreme heat and water scarcity and prevents further ... -
Optimization of lycopene extraction from tomato peels industrial by-product using maceration in refined olive oil
( Institution of Chemical Engineers , 2019 , Article)Lycopene, a nutraceutical compound, was extracted from a Tunisian industrial tomato peels by-product using maceration in refined olive oil (ROO). To do, a Box–Behnken design was applied to maximize the lycopene recovery ... -
Long-term semi-continuous cultivation of a halo-tolerant Tetraselmis sp. using recycled growth media
( Elsevier Ltd , 2019 , Article)In this study, a halotolerant Tetraselmis sp. was selected for 11-month outdoor semi-continuous cultivation in one sq. m raceway tank in the Qatari desert. A fraction of the culture was harvested using ferric chloride, and ... -
Factors affecting the induction of UV protectant and lipid productivity in Lyngbya for sequential biorefinery product recovery
( Elsevier Ltd , 2019 , Article)With objective to design cyanobacterial biorefinery, taking Lyngbya as a model organism, a detail sequential protocol has been developed for production of UV protectant and lipids. This study addresses ultra violet radiations ... -
Water, energy and food supply security in the Gulf Cooperation Council (GCC) countries-A risk perspective
( MDPI AG , 2019 , Article Review)Supply systems for water, energy and food in the Gulf region are becoming highly interlinked. In the last decades, interdependence was evident in the increase of coproduction plants and the cross-sectoral resource use ... -
Comparative scorecard assessment of urban water pricing policies-The case of Jordan and Iran
( MDPI AG , 2019 , Article)Urban water pricing is becoming increasingly important due to the rapid rate of urbanization and the expansion of water reclamation and reuse. The mounting evidence of failures of current pricing schemes makes analyzing ... -
Comparison of biocrude oil production from self-settling and non-settling microalgae biomass produced in the Qatari desert environment
( Center for Environmental and Energy Research and Studies , 2019 , Article)The present study investigated the growth, harvesting, biocrude conversion, and recycling of the HTL aqueous phase for one self-settling (i.e., Chlorocystis sp.) and another non-settling (i.e., Picochlorum sp.) marine ... -
Use of co-solvents in hydrothermal liquefaction (HTL) of microalgae
( MDPI AG , 2019 , Article)This study reviewed and summarized the literature regarding the use of alcohols during hydrothermal liquefaction (HTL) of algal biomass feedstocks. The use of both pure alcohols and alcohol-water co-solvents were considered. ... -
The effect of culture salinity on the harvesting of microalgae biomass using pilot-scale tangential-flow-filter membrane
( Elsevier Ltd , 2019 , Article)In this study, the effect of culture salinity (4–6% NaCl) on the harvesting of two microalgal strains (i.e., Picochlorum sp., and Tetraselmis sp.) was investigated using pilot-scale TFF membranes. The cultures of these two ... -
Evaluation of native microalgae from Tunisia using the pulse-amplitude-modulation measurement of chlorophyll fluorescence and a performance study in semi-continuous mode for biofuel production
