Microbiological and chemical monitoring of Marsala base wine obtained by spontaneous fermentation during large-scale production

2014

The present work was undertaken to evaluate the effect of natural wine making on the microbial and chemical composition of Marsala base wine. To this purpose, a large-scale vinification process of Grillo grape cultivar was monitored from the grape harvest to the final product. Total yeasts (TY) showed a rapid increase after must pressings and reached values that were almost identical to those registered during conventional wine makings. Lactic acid bacteria (LAB) were registered at the highest levels simultaneous to those of yeast growth at the beginning of the process. Saccharomyces cerevisiae was the species found at the highest concentrations in all samples analysed. Several strains (n =…

The Stagnone of Marsala lagoon

2009

The Stagnone of Marsala is an oligotrophic lagoon situated on the western coast of Sicily. The area has been under study since the mid-nineteenth century. Research has focused on its physiographic, chemical-physical, biological, ecological features and, particularly, on submerged vegetation. Its main biotic component, a meadow of Posidonia oceanica, is distributed among peculiar reef formations inside and outside the lagoon, which are extremely interesting from an ecological and environmental point of view. The seagrass grows near to its thermal and salinity tolerance level in the inner lagoon, where it is partially replaced by Cymodocea nodosa and Caulerpa prolifera meadows. Algal assembla…

Investigation of yeast community of “Grillo” grapes and musts from Marsala wine production area.

2009

The oenological interest in the autochthonous yeast applications has increased since they represents an important supplement to wine quality (Martinez et al. 1989; Moreno et al. 1991). Yeast populations harboured onto the surface of berries and in musts of “Grillo” grape variety were isolated and analyzed. In order to obtain a first blastomycetic mapping of Marsala wine production area, eight vineyards were chosen on the basis of different climatic and agronomic parameters, including altitude, exposure,vineyard age, grape biotype, grape cultivation system, vegetative vigour, pruning, green pruning, yield per plant, phytosanity state, irrigation and closeness to wood areas. Analysis of blast…

Examples of anthropogenic sinkholes in Sicily and comparison with similar phenomena in southern Italy

2013

A sinkhole, occurred in June 2011 and related to an underground quarry in the eastern sector of Marsala, is described in this paper as a case study (Figure 2). The site was selected for the availability of topographic data of the underground quarry, prior to the formation of the Abstract Anthropogenic sinkholes affect several built-up areas of Sicily (southern Italy) representing a great risk to people, buildings, and infrastructures. These phenomena are generally associated with the presence of ancient underground quarries for the extraction of calcarenite rock, used for building or ornamental materials. These quarries were poorly constructed and abandoned throughout history.

BIOMONITORAGGIO DELL’INQUINAMENTO ATMOSFERICO MEDIANTE L’USO DI LICHENI COME BIOACCUMULATORI NEL CENTRO URBANO DI MARSALA (TP)

2008

È stato avviato uno studio di biomonitoraggio nel centro urbano di Marsala. Come altre città siciliane, pur non essendo interessata da importanti attività industriali, Marsala è caratterizzata da un inquinamento legato ad attività antropiche minori, quali l’uso dei combustibili fossili per autotrazione, per il riscaldamento domestico e per la navigazione. Il contesto geomorfologico in cui si sviluppa la città, ubicata in una zona pianeggiante, non determina alcun ostacolo importante alla circolazione degli inquinanti operata dai forti e costanti venti che spirano dal mare. Il campionamento è stato effettuato nel gennaio 2007 in 27 stazioni distribuite su un’area di circa 25 km2. In ogni sta…

IL SUCCIACAPRE CAPRIMULGUS EUROPAEUS (Aves Caprimulgiformes) NIDIFICANTE ALLO STAGNONE DI MARSALA (TRAPANI)

The PAH composition of surface sediments from Stagnone coastal lagoon, Marsala (Italy)

2006

Abstract This paper examines the presence, distribution, nature and sources of 22 Aromatic Hydrocarbons (PAHs), which are important environmentally and toxicologically, in sediments from the Stagnone coastal lagoon at Marsala (Italy). Analysis was performed by gas chromatography/mass spectrometry (GC/MS) with selected ion monitoring (SIM). The total concentration of polycyclic aromatic hydrocarbons ranged from 72 to 18381 μg/kg of dry matrix. The relative standard deviation (RSD) of the replicates on the concentrations of individual compounds ranged from 5% to 20%. The accuracy of method was estimated by analyzing “blank” samples added of known quantities of analytes and the recover percent…

Le prove di vinificazione della cultivar grillo su tre vigneti sperimentali site nel sottobacino Iudeo - Bucari (TP).

2014

Gli Autori, dopo aver descrittole caratteristiche ambientali del sottobacino Iudeo Bucari e l’attività agricola prevalentemente legataalla vitivinicoltura, descrivono alcune prove di vinificazione di uve Grillo provenienti da tre vignesite nel sottobacino Iudeo – Bucari gestite in modo ordinario, delle quali si è monitorata la maturazione delle uve. L'obiettivo è quello di caratterizzare il prodotto vino ottenuto attraverso una tecnica di vinificazione uniforme ed ordinaria nella zona, ma che mira a mettere in evidenza la diversa qualità tecnologica delle uve utilizzate espressione dicontesti eco-pedologici diversi.

Changes in the benthic algal flora and vegetation of a semi-enclosed Mediterranean coastal lagoon (Stagnone di Marsala, Western Sicily)

2014

È stato condotto uno studio sulla flora e vegetazione macroalgale dello Stagnone di Marsala (Trapani) con l’obiettivo di fornire una revisione dei dati riportati in letteratura ed esaminare i principali cambiamenti che si sono verificati nell’intera area negli ultimi tre decenni. La flora algale è risultata più povera rispetto al passato (94 taxa contro 108), mostrando un incremento delle Cloroficee e una riduzione delle Rodoficee e delle Feoficee. Solo 48 taxa sono stati riportati precedentemente, mentre 46 sono nuovi per lo Stagnone. Tra questi, è interessante sottolineare sia da un punto di vista floristico che ecologico, il ritrovamento per la prima volta dell’alga bruna Cystoseira comp…
