Fabrication and characterization of poly(vinyl alcohol)-Glycerol-Spinel ferrites flexible membranes
(
John Wiley and Sons Inc.
, 2019 , Article)
Polymer membranes of ferrites nanoparticles, glycerol, and poly(vinyl alcohol) (PVA) were fabricated using a solution casting method. Spinel ferrites nanoparticles, CuFe2O4 or ZnFe2O4, and glycerol were used as dopants to ...
Contribution of major polyphenols to the antioxidant profile and cytotoxic activity of olive leaves
(
Bentham Science Publishers
, 2019 , Article)
Aims: This study was designed to investigate the phytochemical profile and the cytotoxic activities of the eco-friendly extracts of olive leaves from Chemlali cultivar. Materials and Methods: The Phenolic composition of ...
Detoxification assays of tunisian tannery wastewater under nonsterile conditions using the filamentous fungus aspergillus Niger
(
Hindawi Limited
, 2019 , Article)
The ability of Aspergillus Niger strain to reduce organic and mineral pollution as well as the toxicity of two tannery wastewaters, the unhairing effluent (UE) and the final effluent (FE), taken from a local Tunisian tannery ...
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 ...
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 ...
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 ...
Enzymatic pre-hydrolysis of organic fraction of municipal solid waste to enhance anaerobic digestion
(
Elsevier Ltd
, 2019 , Article)
Enzymatic pretreatment was proposed to enhance the anaerobic digestion of Organic Fraction of Municipal Solid Waste (OFMSW). Enzyme cocktails were produced at laboratory scale from Aspergillus niger fermentation on wheat ...
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 ...
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 ...
Effect of harvesting methods on the energy requirement of Tetraselmis sp. biomass production and biocrude yield and quality
(
Elsevier Ltd
, 2019 , Article)
A halo-tolerant Tetraselmis sp. was grown in a 100,000 L raceway pond in the Qatari desert environment. As the biomass density reached 0.679 g/L, after 7 days, five different harvesting methods (i.e., cross-flow filtration, ...
