Potential Synergistic Action of Liquid Olive Fruit Polyphenol Extract with Aqueous Extracts of Solid Wastes of Pomegranate or/and Orange Juice Industry as Organic Phyto-protective Agents against Important Plant Pathogens - Part 1 (in vitro Studies)

“…According to Figure 9 control sample (69) of P. punicae was covered the growth are of the Petri dish after 14 days of incubation at 28 o C. Similar mycelium growths, were also observed in samples 72 (100% orange), 71 (100% pomegranate), 61 (20% olive-32% pomegranate-48% orange), 59 (40% pomegranate-60% orange), 51 (20% olive-48% pomegranate-32% orange), 50 (10% olive-54% pomegranate-36% orange), 49 (60% pomegranate-40% orange), 31 (20 % olive-40% pomegranate-40% orange), 30 (10% olive-45% pomegranate-45% orange), 29 (50% pomegranate-50% orange), 20 (10% olive-63% pomegranate-27% orange), 19 (70% pomegranate-30% orange), 18 (10% olive-90% orange), 17 (20% olive-80% orange), 15 (40% olive-60% orange) and 9 (10 % olive-90% pomegranate). According to Tukey's test, samples 72,71,69,61,59,51,50,49,31,30,29,20,19,18,17,15,9 did not differ statistically important from the control sample number 69. Mycelium growth was not observed in those samples in which olive fruit extracted polyphenol was applied alone at >70% as well as in mixtures with pomegranate at >90%.…”

“…Thus, the interest in the isolation, examination and use of plant tissues and agricultural waste rich in natural polyphenols extracted from various parts of plant species such as thyme, citrus and olive green tea has been expressed by many researchers [59][60][61][62][63][64][65][66][67][68][69][70][71][72][73]. This interest is strongly enhanced since several microorganisms such as fungi, bacteria, viruses, etc., interact in the natural environment with plants [74][75][76] and by them shelves [77] affecting growth and development [78,78,79].…”

“…However, the highest growth of mycelium (even greater than the control 69) was observed in samples 72 (100% orange), 23 (40% olive-42% pomegranate-18% orange), 71 (100% pomegranate), 19 (70% pomegranate-30% orange) and 49 (60% pomegranate-40% orange). According to Tukey's test, the above samples (72,23,71,19,49) 69. It was generally observed that the higher the amount of olive fruit polyphenol present in the mixing of the samples, the more effective the inhibitory effect of the mixtures on E. lata.…”

Recovery of phenols from autohydrolysis liquors of barley husks: Kinetic and equilibrium studies

“…The use of macroporous resins to phenolic fraction valorisation involve higher selectivity, easier desorption, lower solvent consumption, absence of chemical residues in the product, better mechanical strength and ability to reuse (Petrotos et al, 2016). Thus, the adsorption process is preferred because it is a low-cost separation technique, applicable for industrial scale processes, with high adsorption capacities, possible recovery of the adsorbed molecules and easy regeneration (Abdelkreem, 2013;Kammerer et al, 2011;Soto et al, 2011).…”

Resins have been applied for the adsorption of phenolic compounds and hydroxytyrosol from olive oil mill wastewater (Agalias et al, 2007;Frascari et al, 2016;Petrotos et al, 2016Petrotos et al, , 2013, hydroxytyrosol and tyrosol from fermentation brine wastewater (Ferrer-Poloniom et al, 2016), spinacetin and patuletin from spinach leaves (Aehle et al, 2004), polyphenols from kiwifruit juice (Gao et al, 2013), limonin and naringin from orange juice (Ribeiro et al, 2002), hesperidin from orange peel (Di Mauro et al, 1999), anthocyanins from roselle (Chang et al, 2012), narirutin from a water-extract of Citrus unshiu peels (Kim et al, 2007), genistein and apigenin from extracts of pigeon pea roots (Liu et al, 2010), anthocyanins and hydroxycinnamates from orange juice (Scordino et al, 2005), chlorogenic acid and apigenin-7-O-glucoside from artichoke wastewaters (Conidi et al, 2015), catechin, epicatechin, epicatechin gallate, epigallocatechin gallate and caffeine from green tea (Jin et al, 2015; MARK 2016), catechins and theaflavins from black tea (Monsanto et al, 2015). The study of plant extracts is complex due to the interactions of other plant constituents, which could has an impact on phenolic binding (Bretag et al, 2009;Kammerer et al, 2010).…”
