Pectin: A Long-Neglected Broad-Spectrum Antibacterial.

2020

First reported in the late 1930s and first partly explained in 1970, the antibacterial activity of pectin remained almost ignored until the late 1990s. The concomitant emergence of research on natural antibacterials and on new usages of pectin polysaccharides, including those in medicine widely researched in Russia, has led to a renaissance of research in the physiological properties of this uniquely versatile polysaccharide ubiquitous in plants and fruits. Collecting scattered information, this study provides an updated overview on the subtle factors affecting the behaviour of pectin as antimicrobial. Less degraded pectin extracted via acid-free routes, we argue in the conclusions, will so…

According to the CPLL proteome sheriffs, not all aperitifs are created equal!

2014

Combinatorial peptide ligand libraries (CPLLs) have been adopted for investigating the proteome of a popular aperitif in Northern Italy, called "Amaro Branzi", stated to be an infusion of a secret herbal mixture, of which some ingredients are declared on the label, namely Angelica officinalis, Gentiana lutea and orange peel, sweetened by a final addition of honey. In order to assess the genuineness of this commercial liqueur, we have prepared extracts of the three vegetable ingredients, assessed their proteomes, and compared them to the one found in the aperitif. The amaro's proteome was identified via prior capture with CPLLs at two different pH values (2.2 and 4.8). Via mass spectrometry …

In mostra la grande diversità degli agrumi mediterranei

2019

Tra scienza, bellezza, curiosità, a Palermo una grande mostra dedicata al patrimonio genetico degli agrumi ha raccolto decine di tipologie di frutti e reperti artistici legati alle prime forme di agrumicoltura industriale siciliana.

The effects of benzyladenine and meta-Topolin on in vitro sprouting and regrowth after encapsulation of C35 citrange [Citrus sinensis (L.) Osb. × Pon…

C35, a hybrid of ‘Ruby Blood’ sweet orange and trifoliate orange, is a promising Citrus rootstock, mainly due to its resistance to Citrus Tristeza Virus (CTV), one of the most serious pathology affecting citriculture. The use of resistant rootstocks, such as citranges, is an efficient tool to fight this plant disease. This implies a continuous increasing demand of resistant rootstocks, in order to carry out the turnover of sour orange, still the most used Citrus rootstock in Italy. Micropropagation, can provide innovative solutions to obtain, in a short time and in a small space, a number of plants higher than traditional propagation. Micropropagation efficiency is also affected by the cult…

Contenuto minerale delle foglie e qualità dei frutti di agrumi per la trasformazione

2013

In the present study, we analyzed leaf mineral contents fruit quality traits of orange, lemon and tangerine varieties grown in Sicily. The purpose of this research was to individuate chemical or physical fruit quality parameters useful to establish the best possible use of the crop, fresh market or processing. Moreover, leaf mineral analyses were conducted in order to characterize nutritional levels of citrus varieties grown in Sicily. In a second study, we evaluated fruit quality of orange trees cv Valencia in response to deficit irrigation.

Characterization of fruits of four different lemon cultivars, Collected in the northern coast of sicily

2015

The present work is focused on the study of the characteristics of the fruits of four main lemon (Citrus limon L. Burm.) varieties cultivated in Sicily: 'Femminello Comune', 'Monachello', 'Zagara Bianca', and 'Femminello Santa Teresa'. Physical and chemical properties as well as aroma compounds were analysed as quality discrimination factors. Also the effect of the storage conditions was verified. Standard experimental techniques were used to determine: weight, longitudinal and transverse diameters, pH, titratable acidity, total soluble solids, juice percentage and total polyphenols. The volatile component was analysed by i) a gas chromatographer with a mass spectrometer detector and ii) an…

Effect of Sunred metabolic promoter and deficit irrigation on fruit quality of 'Valencia' oranges

2012

This study evaluated the effect of deficit irrigation and Sunred foliar metabolic promoter on fruit quality of adult 'Valencia' orange trees. Three irrigation strategies were imposed in spring 2011: Irrigation with volumes corresponding to 100% of crop evapotranspiration applied to entire root-zone (CI), partial root-zone drying (PRD) with 50% of CI water applied to one alternated side of the root-zone, and continuous deficit irrigation (DI) with 50% of CI water applied to both sides of the root-zone. Four trees in each irrigation treatment were sprayed 30 and 20 days before harvest with Sunred metabolic promoter containing phenylalanine, methionine, mono-saccharides and oxylipins from plan…
