In this paper, industrial dyes, Disperse Red and Disperse Orange, were studied as model pollutants to show the excellent performance of olive pomace (OP) in sequestering and recovering these dangerous dyes from wastewater. The nature of interactions involved between dyes and OP were inferred by changing several parameters: contact time, pomace dosage, pH and temperature values. Visible spectros...

Instant controlled pressure drop (DIC) has been used as a pre-treatment to increase extractable polyphenols (EPP), mainly attributed matrix structure expansion. This work aimed evaluate the effect of DIC on non-extractable (NEPP), EPP, and dietary fiber grape pomace. At 0.2 MPa–60 s was observe an total EPP anthocyanins. Despite increment lowest anthocyanins proanthocyanidins content at 0.4 MPa...

The use of agroindustrial wastes not only decreases bioprocesses and disposal costs but also contributes to the upgrading of the residues. An active recombinant methanol-inducible bovine chymosin has been expressed in our laboratory in the yeastKomagataella pastoris, and grape pomace extracts (GRE) were proposed as a convenient C-energy source for the biomass production of the genetically engin...

Annually, wine production is responsible for generating large quantities of residues, which are frequently disposed and not valorized. So far, different studies have been conducted on grape pomace, yet less attention has paid to other such as lees diatomaceous earth used in filtration. In this context, study aimed evaluate compare the phenolic profile these underexploited winemaking residues as...

Salmonella enterica has been frequently linked to major foodborne disease outbreaks. The molecular mechanisms underlying this pathogen survival on the fresh fruit surface remain largely unexplored. In this study, the environmental factors that affect the survival of Salmonella strains on the surface of selected fruits were studied. Grape tomatoes (or cantaloupe peels) were inoculated in three s...

Seven treatments (activated charcoal, bentonite, PVPP, yeast cell walls, potassium caseinate, zeolite and grape seed oil) were evaluated for their efficacy in decreasing the concentration of geosmin, responsible for earthy off-flavour in wine. In the red wine the potassium caseinate and grape seed oil treatments decreased the concentration of geosmin by 14% and 83%, respectively, while in the w...

Polyhydroxyalkanoates (PHA) are biodegradable bioplastics of interest as potential substitutes petroleum-derived plastics that can be produced starting from lignocellulosic-derived residues. This study presents the combined solid-state enzymatic hydrolysis (SSEH) and fermentation (SSF) a sustainable approach for obtaining PHA using leftovers brewer's spent grain (BSG), grape pomace (GP) olive-m...

Plant protection based on novel alternative strategies is a major concern in agriculture to sustain pest management. The marc extract of red grape cultivars reveals plant defence inducer properties. Treatment with grape marc extract efficiently induced hypersensitive reaction-like lesions with cell death evidenced by Evans Blue staining of tobacco leaves. Examination of the infiltration zone an...
