(
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 ...
A comparative study of the growth of Tetraselmis sp. in large scale fixed depth and decreasing depth raceway ponds
(
Elsevier Ltd
, 2016 , Article)
In this study, an alternative approach was proposed where excess seawater would be added only during inoculation (DD) rather than daily addition (FD). Growth and metabolite contents of Tetraselmis sp. weren't affected for ...
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 ...
Microalgae harvesting by pH adjusted coagulation-flocculation, recycling of the coagulant and the growth media
(
Elsevier Ltd
, 2016 , Article)
Coagulation-flocculation can be considered as one of the least energy intensive microalgae biomass harvesting processes. However, cost of the coagulant and biomass contamination are two critical issues that need to be ...
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 ...
Evidence of thermo and halotolerant Nannochloris isolate suitable for biodiesel production in Qatar Culture Collection of Cyanobacteria and Microalgae
(
Elsevier
, 2016 , Article)
The isolation of autochthonous microalgae, with high lipid-contents and biomass productivities is a crucial aspect of the development of commercial production of microalgae-based biodiesel as well as food security in ...
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 ...
