Journal ArticleDOI
Extraction and characterization of an alginate from the brown seaweed Sargassum turbinarioides Grunow
Taratra Andrée Fenoradosoa,Ghina Ali,Cédric Delattre,Céline Laroche,Emmanuel Petit,Anne Wadouachi,Philippe Michaud +6 more
TL;DR: Matrix polysaccharide from the brown algae Sargassum turbinarioides collected in the coastal waters of Nosy Be (Madagascar) in the Indian Ocean was isolated and its structure was studied by 1H-NMR spectroscopy, FT-IR, SEC-MALLS and HPAEC.
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
Induction of natural defence accompanied by salicylic acid-dependant systemic acquired resistance in tomato seedlings in response to bioelicitors isolated from green algae
Cherkaoui El Modafar,Mohamed Elgadda,Redouan El Boutachfaiti,Elfaiza Abouraicha,Naima Zehhar,Emmanuel Petit,Zainab El Alaoui-Talibi,Bernard Courtois,Josiane Courtois +8 more
TL;DR: Results showed clearly that U. lactuca elicitors, particularly the ulvan and the oligoulvans, induced in tomato seedlings the stimulation of natural systemic defences accompanied by a systemic acquired resistance that seems to be salicylic acid-dependent.
Separation and fractionation of exopolysaccharide from Porphyridium cruentum
Anil Kumar Patel,Alina Ursu Violeta,Céline Laroche,Alain Marcati,Alina V. Ursu,Sébastien Jubeau,Luc Marchal,Emmanuel Petit,Gholamreza Djelveh,Philippe Michaud +9 more
TL;DR: D Diafiltration (DF) using a membrane with a 300 kDa molecular weight cut off was the most efficient technique compared to solvent-extraction and dialysis methods for EPS fraction characterized in terms of rheological properties and biochemical content.
Journal ArticleDOI
Polyglucuronic acids: Structures, functions and degrading enzymes
TL;DR: This review focuses on this class of polyuronides and the enzymes capable of cleaving them and the description of a new polysaccharide lyase family.
