Modulation of geraniol metabolism during alcohol fermentation
2004
J. Inst. Brew. 110(3), 213–219, 2004 Geraniol is the main monoterpenol present in Gewurtztraminer white grapes and in some red aromatic grapes from northern Italy. During fermentation, the geraniol concentration showed a dramatic drop and a small amount was transformed into linalool and -terpineol by an acid catalysed chemical reaction. Yeast are responsible for changing most of the geraniol to citronellol through enzymatic reactions. The final aroma of wine is due mainly to both the untransformed geraniol and the formed citronellol. In this study, competition between the geraniol-citronellol transformation and another metabolic process, in which according to our hypothesis sterol biosynthe…
Antilisterial effect of citrus essential oils and their performance inedible film formulations
2016
[EN] The antimicrobial activity of eight essential oils (EOs) extracted from the fruit peel of Citrus genotypes (orange, mandarin and lemon) was evaluated against 76 strains of Listeria monocytogenes, previously isolated from different food matrices. EOs showing the most (EO L2 and EO L8) and least (EO O3 and EO M7) effective inhibition activities were chemically characterized by gas chromatography coupled with mass spectrometry (GC/MS) to compare their composition. EO L2 and EO L8 were chosen to determine the MIC and to evaluate the cell viability of the most sensitive strains (L. monocytogenes LM35 and LM69) after 1, 2, 4 and 6 h of exposure. The effectiveness of chitosan (CH) and methylc…
Saccharomyces cerevisiae signature genes for predicting nitrogen deficiency during alcoholic fermentation
2007
Genome-wide analysis of the wine yeast strain Saccharomyces cerevisiae PYCC4072 identified 36 genes highly expressed under conditions of low or absent nitrogen in comparison with a nitrogen-replete condition. Reverse transcription-PCR analysis for four of these transcripts with this strain and its validation with another wine yeast strain underlines the usefulness of these signature genes for predicting nitrogen deficiency and therefore the diagnosis of wine stuck/sluggish fermentations.

L'architettura dei padiglioni dell'alimentazione e della ristorazione nelle esposizioni dell'Oltremare del Secondo Imperialismo
2014
Il periodo compreso fra le rivoluzioni liberali del 1848 e lo scoppio della seconda guerra mondiale nel 1939 (che dà il via al tramonto della cosiddetta “età aurea” del sistema capitalista e della supremazia del “vecchio continente” sul resto del mondo), pur in maniera difforme, è caratterizzato da un nuovo scenario economico e tecnologico della civiltà occidentale che riconosce nelle grandi esposizioni internazionali e nazionali, ma anche in quelle regionali e coloniali, le sedi più idonee per azioni di propaganda commerciale e politica. L’origine del genere delle esposizioni coloniali, che prende il via in sordina e con sensibile ritardo, è puramente mercantilistica e si manifesta inizial…

Grapevine and wine metabolomics-based guidelines for fair data and metadata management
2021
In the era of big and omics data, good organization, management, and description of experimental data are crucial for achieving high-quality datasets. This, in turn, is essential for the export of robust results, to publish reliable papers, make data more easily available, and unlock the huge potential of data reuse. Lately, more and more journals now require authors to share data and metadata according to the FAIR (Findable, Accessible, Interoperable, Reusable) principles. This work aims to provide a step-by-step guideline for the FAIR data and metadata management specific to grapevine and wine science. In detail, the guidelines include recommendations for the organization of data and meta…
Subcellular localization of bacteriophage PRD1 proteins in Escherichia coli
2014
Bacteria possess an intricate internal organization resembling that of the eukaryotes. The complexity is especially prominent at the bacterial cell poles, which are also known to be the preferable sites for some bacteriophages to infect. Bacteriophage PRD1 is a well-known model serving as an ideal system to study structures and functions of icosahedral internal membrane-containing viruses. Our aim was to analyze the localization and interactions of individual PRD1 proteins in its native host Escherichia coli. This was accomplished by constructing a vector library for production of fluorescent fusion proteins. Analysis of solubility and multimericity of the fusion proteins, as well as their …
