Aqueous extraction of proteins from microalgae: Effect of different cell disruption methods
Carl Safi,Carl Safi,Alina-Violeta Ursu,Céline Laroche,Bachar Zebib,Bachar Zebib,Othmane Merah,Othmane Merah,Pierre-Yves Pontalier,Pierre-Yves Pontalier,Carlos Vaca-Garcia,Carlos Vaca-Garcia,Carlos Vaca-Garcia +12 more
TL;DR: The microalgal structure has been investigated to evaluate the release of proteins in aqueous media from five microalgae after conducting different cell disruption techniques: manual grinding, ultrasonication, alkaline treatment, and high-pressure treatment.
Journal ArticleDOI
Extraction, fractionation and functional properties of proteins from the microalgae Chlorella vulgaris.
Alina-Violeta Ursu,Alain Marcati,Thierry Sayd,Véronique Santé-Lhoutellier,Gholamreza Djelveh,Philippe Michaud +5 more
TL;DR: Better emulsifying capacity was obtained when protein solubilisation takes place at pH=7 and when using proteins from permeate of tangential ultrafiltration, and stability of microalgae proteins remained comparable or higher than the commercial ingredients such as sodium caseinate.
Journal ArticleDOI
Separation and fractionation of exopolysaccharides from Porphyridium cruentum
Anil Kumar Patel,Céline Laroche,Alain Marcati,Alina-Violeta Ursu,Sébastien Jubeau,Luc Marchal,Emmanuel Petit,Gholamreza Djelveh,Philippe Michaud +8 more
TL;DR: In this article, the extraction of EPSs from culture media of Porphyridium cruentum, by dialysis, solvent-precipitation with 3 polar alcohols (methanol, ethanol and isopropanol) and membrane separation techniques has been studied.
Journal ArticleDOI
Metal removal through synergic coagulation–flocculation using an optimized chitosan–montmorillonite system
Elias Assaad,Abdelkrim Azzouz,Denisa Nistor,Alina-Violeta Ursu,Tudor Sajin,D. Miron,Frédéric Monette,Patrick Niquette,Robert Hausler +8 more
TL;DR: In this article, metal ion removal from water by coagulation-flocculation of the chitosan-montmorillonite system was investigated through factorial 3 3 experimental designs.
Journal ArticleDOI
Assessment of acid–base strength distribution of ion-exchanged montmorillonites through NH3 and CO2-TPD measurements
Abdelkrim Azzouz,Denisa Nistor,D. Miron,Alina-Violeta Ursu,Tudor Sajin,Frédéric Monette,Patrick Niquette,Robert Hausler +7 more
TL;DR: In this article, the acid-base distribution of various ion-exchanged montmorillonites was assessed through thermal programmed desorption (TPD) of NH3 and CO2.
