Genetic and morphometric variation of Mediterranean hake, Merluccius merluccius, in the Strait of Sicily (Central Mediterranean)

2004

Allozyme, morphometric and growth analyses were applied to samples collected in the Strait of Sicily (central Mediterranean Sea) to test the hypothesis of the existence of a unique hake stock (Merluccius merluccius) in the study area. The level of genetic variation was detected from five polymorphic loci (ADH*, PGI-1*, PGI-2*, PGM*, SOD-1*). The average observed heterozygosity amounted to 0.421, while the average expected was 0.353. Weir & Cockerham statistics showed no heterogeneity, except for the single PGI? locus (theta = 0.011; P 0.05). Morphometric analyses revealed some differentiation. Females showed different relationships in six out of eight morphometric indices with total length,…

Chitosan films for the microbiological preservation of refrigerated sole and hake fillets

2013

The effect of chitosan films for shelf-life extension of fresh fillets of hake (Merluccius merluccius) and sole (Solea solea) was evaluated over a 15-day storage at 4 ± 1 °C. Fish fillets wrapped in a chitosan matrix were individually packaged in air (AP) and under vacuum (VP). Microbiological analyses (total aerobic mesophilic bacteria, Pseudomonas, H2S-producing bacteria, lactic acid bacteria, Enterobacteriaceae and Listeria monocytogenes were carried out during the shelf-life. The microbial species were inhibited (p < 0.05) by the presence of chitosan films, especially under VP conditions. A significant (p < 0.05) increase of the lag phase and a reduction of the final microbial populatio…

Micropropagazione di Convolvulus sabatius Viv.

2015

Il genere Convolvulus, appartenente alla famiglia delle Convolvulaceae, comprende circa 250 specie annuali e perenni, molte delle quali sono considerate infestanti. Tuttavia, alcune specie come C. tricolor, C. cneorum e C. sabatius vengono inserite nel settore delle piante ornamentali (Bird, 2004). Specie erbacea perenne, originaria del bacino del mediterraneo, C. sabatius è rinvenibile nella nostra penisola allo stato spontaneo in Liguria, Puglia e Sicilia (Pignatti, 2003). La specie, per il valore estetico dei numerosi fiori azzurro-violetti, il lungo periodo di fioritura (aprile-giugno) e la capacità di adattamento sia ad alte che a basse temperature (la pianta tollera temperature fino a…

Metabolites from Mediterranean plant: characterization and trasformation. chemotaxonomic assessmentand biological activity

2016

Questo progetto di ricerca ha lo scopo di ampliare le conoscenze di alcune piante appartenenti alla flora Mediterranea. Le piante da studiare sono state scelte in seguito ad un’attenta analisi bibliografica tra specie poco sudiate. La scelta è quindi ricaduta su nove specie appartenenti al genere Anthemis, due specie appartenenti al genere Pulicaria e sulle specie di Tetraclinis articulata, Salvia argentea, Ajuga tenorei, Ballota hispanica, Moluccella Spinosa e Thapsia garganica. Di esse sono stati preparati ed identificati i componenti degli oli essenziali e successivamente effettuati su di essi i saggi antibatterici. Dagli estratti delle specie di Tetraclinis articulata e Ajuga tenorei so…

Tecniche di Produzione del Cemento Traslucido

2012

The aim of the paper is to investigate different techniques used by some companies nowadays involved in the production of panels or blocks made of translucent cement. For doing that, the patents registered all over the world starting from the 2000 have been studied in deep, in order to acquire more detailed information about the techniques of production and to overcome the limits due to the lack of information about this subject that is difficult to find in literature. Particularly, patents by LitraConTM, Luccon, Lucem, Italcementi have been investigated; these last four industries are, at the moment, the only ones able to make in Europe translucent cement elements by using different techni…
