Microbial safety of black summer truffle collected from Sicily and Umbria Regions, Italy
2021
Background: Tuber aestivum Vittad., known as black summer truffle, represents high-value food especially used as garnishment in nouvelle cuisine. The aim of this study was to investigate on the viable microbial populations associated with T. aestivum ascomata collected in different sites of Sicily and one locality of Umbria (Italy).
 Methods: The ripe ascomata of black summer truffles were collected from Central Italy. Cell densities of spoilage bacteria, fecal indicators, potential pathogens, yeasts, and molds were analyzed. Statistical analysis was conducted with XLSTAT software.
 Results: The microbiological counts of truffles ranged between 6.00 and 9.63 log Colony Forming Uni…

La pratica riflessiva nell’esperienza di tirocinio come strumento di formazione e orientamento alla professione di insegnante di sostegno di scuola s…
2022
A partire dall’approccio metodologico della Narrative Inquiry, è stata realizzata la raccolta e l’analisi di 418 relazioni di tirocinio di altrettanti tirocinanti in formazione che hanno frequentato nel periodo compreso tra gennaio e giugno 2021 il percorso di Specializzazione per le attività di sostegno per la Scuola secondaria di primo e secondo grado dell’Università degli Studi di Palermo. La ricerca intende mettere in risalto l’importanza della pratica riflessiva come dispositivo innovativo di sviluppo profes-sionale e orientamento sul proprio agire didattico, in una dimensione che coniuga le conoscenze teoriche e l’applicazione pratica delle stesse. L’analisi dei risultati conferma l’a…
The decline of the cork oak growing in Sicily is accompanied by the loss of the functions proper to agroforestry systems
2021
The cork oak is one of the most important tree species in the Mediterranean basin, where it covers more than 2 million hectares. Among evergreen oaks, Quercus suber stands out for the variety of cultural systems in which it has been successfully employed, including typical agroforestry systems. Accordingly, a wide range of ecosystem services may be associated to cork oak, including the preservation of biodiversity, carbon sequestration and forage production. In the Mediterranean, the cork oak represents a key species for many natural and seminatural landscapes and habitats, as well as playing a prominent role for the economic and social development of local communities. However, there is in…
Essential oils and their applications in agriculture and agricultural products: a literature analysis through VOSviewer.
2022
In agriculture, more attention has been paid to limit the amount of chemical plant protection products. A potential alternative solution has been found in essential oils (EOs), which appear as promising candidates for their properties (safe, bioactive, biodegradable products) in managing plant diseases in agriculture. Therefore, a co-occurrence analysis was carried out on the available literature on Scopus database, through network maps created by VOSviewer software in order to identify the EOs used in agriculture, agricultural products and their target application. USA and India appeared as the most productive countries in terms of documents and citations followed by Iran and Italy. The co…
RNA2-encoded VP37 protein of Broad bean wilt virus 1 is a determinant of pathogenicity, host susceptibility, and a suppressor of post-transcriptional…
2020
Abstract Broad bean wilt virus 1 (BBWV‐1, genus Fabavirus, family Secoviridae) is a bipartite, single‐stranded positive‐sense RNA virus infecting many horticultural and ornamental crops worldwide. RNA1 encodes proteins involved in viral replication whereas RNA2 encodes two coat proteins (the large and small coat proteins) and two putative movement proteins (MPs) of different sizes with overlapping C‐terminal regions. In this work, we determined the role played by the small putative BBWV‐1 MP (VP37) on virus pathogenicity, host specificity, and suppression of post‐transcriptional gene silencing (PTGS). We engineered a BBWV‐1 35S‐driven full‐length cDNA infectious clone corresponding to BBWV‐…
Arbuscular mycorrhizal fungi positively affect growth of Ailanthus altissima (Mill.) Swingle seedlings and show a strong association with this invasi…
2015
Arbuscular mycorrhizal fungi (AMF) may promote plant invasion by enhancing plant performance and competitiveness. However, only a small number of studies have considered the interactions between local soil microbial communities and invasive plants, and even fewer have focused on alien trees. Ailanthus altissima is a serious problem in the Mediterranean Basin, where it has invaded many habitats. We investigated the symbiosis between A. altissima and indigenous AMF in two invaded, ecologically different Mediterranean woodlands. Mycorrhizal infection was high at both sites (> 60% of the root fragments were mycorrhizal), indicating that A. altissima roots may be infected by AMF under different …
AILANTHUS ALTISSIMA (MILL.) SWINGLE (Simaroubaceae) IN SICILIA E CENNI STORICI SULLA SUA INTRODUZIONE IN ITALIA
2012
Nonostante la diffusa presenza dell’ailanto in Sicilia, mancavano sino ad oggi studi specifici a carattere regionale su questa specie arborea esotica invasiva. Allo scopo di colmare alcune di queste lacune, il presente lavoro si è posto cinque obiettivi: 1) ripercorrere la storia della diffusione globale dell’ailanto, prestando particolare attenzione all’Italia ed alla Sicilia; 2) analizzare le cause (antropiche e biologiche) della sua spiccata invasività a livello globale e locale; 3) fornire un primo quadro della sua distribuzione e della sua auto- e sinecologia sul territorio regionale; 4) stabilire i metodi più idonei ed efficaci per contenerne la diffusione e ridurne l’impatto ecologic…
Les dynamiques du périurbain dijonnais entre 1990 et 1999
2009
Un étalement urbain accompagne désormais la croissance des villes, notamment les plus grandes. Principalement expliqué par un desserrement résidentiel, il est aussi la résultante des dynamiques de centralisation de l’emploi et de spécialisation des zones d’activité à l’intérieur des aires urbaines. L’exemple dijonnais met bien en lumière ce double mouvement qui affecte les communes de sa périphérie et contribue à accroître les mobilités. Urban sprawl arises from the growth of cities, especially of the biggest cities. This urban sprawl is accounted for mainly by residential clearing. It results also from the dynamics of centralization of employment and from specialization of activity zones i…
Le fortificazioni di Akragas: il settore presso la cosiddetta Porta Aurea
2020
L’identificazione della porta ad mare ferens, ricordata da Livio per le vicende della conquista romana di Agrigento nel 211/0 a.C., ha costituito uno degli argomenti di maggior interesse per gli studiosi della topografia della città, in connessione con la localizzazione dell’agorà-foro e del non lontano tempio di Eracle/Ercole. Nel quindicennio scorso ha prevalso l’ipotesi, avanzata da G. Tripodi nel 2003, che la porta principale di collegamento con la costa sia da ubicare a Est (attuale giardino di Villa Aurea) e non già ad Ovest (sito della cosiddetta Porta Aurea) del Tempio A/ cosiddetto Tempio di Eracle; da ultimo, V. Caminneci e G. Cucchiara hanno invece rivalutato l’importanza anche d…
