Changes in antioxidant metabolism because of the effect salinity stress (0, 80, 160 or 240 mM NaCl) on protective enzyme activities under ambient (350 micromol mol(-1)) and elevated (700 CO(2) concentrations were investigated two barley cultivars (Hordeum vulgare L., cvs Alpha Iranis). Electrolyte leakage, peroxidation, [superoxide dismutase (SOD), EC 1.15.1.1; ascorbate peroxidase (APX), 1.11.1.11; catalase (CAT), 1.11.1.6; dehydroascorbate reductase (DHAR), 1.8.5.1; monodehydroascorbate...
Sunflower seedlings ( Helianthus annuus cv. Licia Stella) reached a mild, moderate and severe level of water deficit stress after 5, 8 11 days soil depletion, respectively. At stress, an elastic adjustment occurred. the same time, in response to minor osmotic potential (Ψ π ) intermediate rate w decrease, glutathione increased enzyme activities related ascorbate/glutathione cycle were induced. efficiency this defence mechanism fell, oxidative processes intensified soluble protein content...
Abstract The increasing demand for healthy baked goods boosted studies on sourdough microbiota with beneficial metabolic traits, to be used as potential functional starters. Here, 139 yeasts isolated from cereal-based fermented foods were in vitro characterized their phytase and antioxidant activities. molecular characterization at strain level of the best 39 performing isolates showed that they did not derive cross contamination by baker’s yeast. Afterwards, vivo analyzed leavening ability,...
Raphanus sativus L. cv. Rimbo was grown for 10 days after emergence in hydroponic culture containing 0.12 (control), 5, and 15 µ M copper. The seeds were germinated the presence of copper solution. Cu contents increased with treatment both shoots roots, maintaining roots a value eight‐ to ten‐fold higher than shoots. With underwent growth inhibition an increase percentage dry weight. Membrane damage lipid peroxidation glutathione oxidized as concentration increased, indicating acceleration...
Changes in the lipid composition and fluidity of PSII‐enriched thylakoids were studied seedlings wheat ( Triticum durum Desf. cv. Adamello) grown nutrient solution supplemented with CuSO 4 to achieve a final concentration 10 50 μ M Cu. Metal content increased chloroplasts Cu‐grown plants. PSII isolated from supplied Cu did not show any alteration or protein levels membranes, nor was change ultrastructure membranes detected. The plants showed thylakoid swelling, particularly stroma terminal...

Ramonda serbica plants dehydrated for 14 days reached a relative water content of 4.2% and entered into anabiosis prior to being rehydrated 48 h. Total ascorbate (AsA + DHA) glutathione (GSH GSSG) contents increased during dehydration approached control values by the end rehydration. Reduced (AsA) (GSH) were consumed first 13 when guaiacol‐, syringaldazine‐ phenolic peroxidases (EC 1.11.1.7) increased. At AsA GSH accumulated whereas decreased half value controls. In this period, R. face...
The aim of the present research was to study effects olive leaf addition (0 and 3%) on major antioxidants antioxidant activity Neb Jmel Oueslati oils. Olives leaves two Tunisian varieties were harvested during 2016/2017 crop season. Both oils characterised for their concentrations in phenolics, tocopherols power. Other parameters such as free acidity, peroxide value, chlorophyll carotenoid also taken into consideration. Compared Oueslati, oil showed a lower acidity (50%) value (5.6-fold),...
This work investigated the effect of nitrogen fertilization and harvest time on flavonoid composition antioxidant properties Stevia rebaudiana leaves. At same time, changes in stevioside (Stev) rebaudioside A (RebA) contents were recorded. pot trial under open air conditions was set up, testing five N rates three times. The results showed that, by using an adequate rate choosing appropriate it possible to significantly increase optimize bioactive compound levels. In particular, higher RebA,...
The aim of this work is to evaluate the effectiveness different inert gases, other than nitrogen, develop a preservation method that can maintain high quality extra virgin olive oil (EVOO) increasing its shelf life. EVOO stored in dark at 12 °C glass containers for about 9 months, and Ar CO 2 are selected as alternative head‐space gases comparison with air. While acidity remains constant during whole observation period, oxidation‐sensitive parameters show significant differences over time...
Copper is a catalyst in the formation of reactive free radicals and its toxicity may be due, at least part, to oxidative damage. The response thylakoid‐bound stromal antioxidative enzymes against generation superoxide radical was investigated seedlings wheat ( Triticum durum L. cv. Adamello) grown hydroponic culture for 10 days subjected 50 µ M copper treatments. Electron spin resonance roots evidenced spectrum copper, intensity which increased with treatment, whereas carbon‐centered...
Two wheat (Triticum durum Desf.) cultivars with different sensitivities to drought were either grown under regular irrigation or subjected water deficit by withholding for 14 d. Water-stressed plants of both underwent similar decreases in leaf potential, but the drought-tolerant cultivar showed higher relative content and turgor. Neither osmotic nor elastic adjustment mechanisms appeared be active conditions described here. Thylakoids isolated from stressed, an increase lipid-to-protein...
The aim of this study was to assess whether the nutritional value cherry tomato can be improved by irrigating plants with diluted seawater (12%; EC = 10 mS/cm in comparison a control at 4 mS/cm). Berries cv. Naomi were analyzed red-ripe stage for contents NADPH and NADP+ as well amounts main antioxidants, such ascorbic acid, lipoic tocopherols, phenolic acids. As compared controls, fruits salt-treated showed higher titratable acidity concentration reducing sugars. picked from irrigated...
This research aimed to study the effects of packaging and storage temperature on shelf-life an extra virgin olive oil (EVOO) as it can occur in most points sale. The evolution chemical sensory characteristics EVOO, initially stored stainless steel silos under nitrogen at 12-18 °C, was evaluated after packaging. Tinplate tin (TT) greenish glass (GG), used containers, temperatures 6 26 °C were taken into consideration. After 125 days from all samples maintained clearness, green yellow...
