Transesterification of used cooking sunflower oil catalyzed by hazelnut shell ash
(Renewable Energy, 2022)
Hazelnut shell ash was investigated as a new base catalyst for the transesterification of used cooking sunflower oil to biodiesel. To understand its catalytic properties, the prepared ash was characterized by EDX, XRD, ...
Extraction of lyophilized olive mill wastewater using supercritical CO2 processes
(Alexandria Engineering Journal, 2022)
The olive growing in Tunisia has an economic dominance and agricultural importance. However, the huge extraction of olive oil generates a large quantity of olive mill wastewater (OMW), which is discharged to the surroundings. ...

(Biomass Conversion and Biorefinery, 2023)
This study demonstrated the innovative biotransformation aspect of spent coffee grounds (SCG) by application of the specific enzymatic cocktail with addition of lactic acid bacteria strain Lactobacillus rhamnosus (ATCC (R) ...
Dispersive Solid–Liquid Microextraction Based on the Poly(HDDA)/Graphene Sorbent Followed by ICP-MS for the Determination of Rare Earth Elements in Coal Fly Ash Leachate
(MDPI, 2022)
A dispersive solid-phase microextraction (DSPME) sorbent consisting of poly(1,6-hexanedi-ol diacrylate)-based polymer microspheres, with embedded graphene microparticles (poly(HDDA)/g-raphene), was synthesized by microfluidic ...
Novel Biocomposite Films Based on High Methoxyl Pectin Reinforced with Zeolite Y for Food Packaging Applications
(Foods, 2022)
Pectin is a natural biopolymer with broad applications in the food industry and it is suitable to prepare edible films to prolong food shelf-life. However, the main limitation of pectin-based films is their poor mechanical ...
Continuous production of fructo-oligosaccharides using selectively immobilized fructosyltransferase from Aspergillus aculeatus onto Purolite® A109
(Korean Society of Industrial Engineering Chemistry, 2023)
Within this study, the investigation of potential selective immobilization of fructosyltransferase (FTase) derived from Aspergillus aculeatus (from commercial enzyme preparation Pectinex® Ultra SP-L) onto the polystyrenic ...
