(
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 ...
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 ...
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 ...
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 ...

(
BMC
, 2019 , Article)
Background
Proteases are hydrolytic enzymes that catalyze peptide linkage cleavage reactions at the level of proteins and peptides with different degrees of specificity. This group draws the attention of industry. More ...
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 ...
Microalgal nutrients recycling from the primary effluent of municipal wastewater and use of the produced biomass as bio-fertilizer
(
Center for Environmental and Energy Research and Studies
, 2019 , Article)
Availability of N, P and other trace metals in municipal wastewater (MWW) makes it very attractive to produce microalgae biomass using MWW. Although limited organic carbon is available in MWW, supplementing flue gas as CO2 ...
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 ...
