An integrated technological approach to the selection of lactic acid bacteria of flour origin for sourdough production
2013
article i nfo Several lactic acid bacteria (LAB) were evaluated in situ for their potential in sourdough fermentation. The strains belonged to Lactobacillus plantarum, Lactobacillus sakei, Lactobacillus sanfranciscensis, Leuconostoc citreum, Leuconostoc mesenteroides, Leuconostoc pseudomesenteroides and Weissella cibaria. LAB were used, in individual inocula, to carry out the fermentation of γ-ray treated (sterile) flour and untreated commercial flour, in order to evaluate their performances both in the absence and presence of the native microbiota of flour. The pH and total titratable acidity (TTA) showed a strong and fast acidification of the experimental sourdough determined by W. cibari…
Cropland versus Gariga schrubland on soil organich carbon storage under Mediterranen climatic of Sicily
2009
Soil organic carbon (SOC) pool is the largest among the terrestrial pool and it plays a key role to mitigate climate change. The restoration of SOC pool represents a potential sink for atmospheric CO2. Land use is one of the most important factors controlling organic carbon content. The main land uses throughout the Mediterranean are croplands (olive, wheat and vineyards) and scrublands. The land abandonment or the reclamation of land is changing the cover of scrubland and cropland. This will change the carbon cycle. The aim of this work is determining the direction and magnitude of soil organic change associated with land use change under Mediterranean Climatic Conditions. Using both histo…

Protein and β-ODAP content and their association with yield contributing traits in selected grass pea lines
2009
Eight selected grass pea (Lathyrus sativus L.) lines were evaluated over three different growing seasons (2005-2008) at the experimental field at the ‘Sparacia farm’ (Cammarata-AG) in Sicily. A randomized complete-block design with three replicates was adopted. 35 viable seeds/m2 of each line were placed at the end of autumn in rows distant 50 cm. After one summer ploughing, 90 kg ha-1 di P2O5 were filled during two harrowing before sowing; later two manual weeds control were performed. Harvest was executed at full maturity of pods (end of the spring). Temperature values and effective rainfall for each season were recorded. Information are presented on the variability in storage seed protei…
Integrating soil survey, land use management and political ecology: A case study in a border area between Peru and Ecuador
2013
In Latin America countries, competition for access to natural resources among different groups has been a major reason for the outburst of violence over the last decades. One of the main aims of the political ecology concerns the understanding of the environmental conditions that can underlies the social conflict among people. Such understanding needs to be based on a detailed investigation of the natural resources of the landscape, mainly the soils. Few years ago the Italian Ministry for Foreign Affairs financed a soil survey with a humanitarian purpose: the development of a peace plan between Peru and Ecuador by improving the socio-economic conditions of the rural populations living in th…
Effect of organic fertilization treatments on grasspea (Latyrus sativus L.)
2013
A better knowledge of important relationships between soil and crop production is necessary to develop sustainable agricultural systems. It is often stated that only a few staple crops produce the majority of the food supply. This might be correct but the important contribution of many minor species should not be underestimated. Legumes have always been used as a source of nutrient-rich organic matter and nitrogen for crops. The grass pea (Lathyrus sativus L.) is a food, feed and fodder crop belonging to the family Leguminosae . This crop has over the past decade received increased interest due to its adaptability to arid conditions and contains high levels of protein, a component that is i…
Composition and variability of the essential oil of the flowers of Lavandula stoechas from various geographical sources
2015
Samples of flowers of wild Lavandula stoechas L. spp. stoechas populations were collected in three areas of Sicily (Italy) and were characterized in agronomic and chemical terms. Essential oil (EO) was extracted by hydrodistillation and analyzed by GC-FID and GC-MS. GC-FID and GC-MS analyses permitted identification of 89 compounds from the EO. The samples were separated into 3 groups using PCA (Principal Component Analysis) statistical method, with reference to the chemical composition of the EO. All three Sicilian populations of lavender were identified as the fenchone chemotype with percentage content ranged between 52.8–71.1%. The population of Partinico showed the highest dry weight o…
Ruolo delle piante officinali nella salvaguardia della biodiversità negli ambienti mediterranei
2008
Mediterranean Italian lands have a considerable plant biodiversity, and Medicinal and Aromatic Plants (MAPs) play a significant role inside it. Some preliminary trials carried out by the DAAT (Dipartimento di Agronomia Ambientale e Territoriale – Department for Land and Environmental Agronomy) of the University of Palermo had the goal to evaluate the suitability of three native species (Hyssop, St. John’s Wort, Lavender) with an herbal interest to the field cropping conditions. The research activity has been carried out in the experimental farm “Sparacia” (Cammarata - AG – Sicily, 37° 38' N - 13° 46' E; 415 m a.s.l.) from 2006 to 2007. The trials confirmed the good suitability of the tested…
Biodiversità e caratteristiche bio-agronomiche in lenticchia (lens culinaris medik.).
2016
Tra le leguminose da granella la lenticchia (Lens culinaris Medik.), occupa un posto importante nella alimentazione umana, per la quantità e qualità di proteine contenute nel seme e per il contenuto di carboidrati associati alla bassa presenza di sostanze antinutrizionali. La coltivazione della lenticchia è ancora basata, nella maggior parte del mondo, su ecotipi locali e solo in pochi Paesi, come il Canada, si utilizzano varietà selezionate. La coltura, come molte leguminose minori, risulta poco presente negli ordinamenti colturali italiani e, negli ultimi decenni, la superficiecoltivata ha registrato una notevole riduzione a causa di ,molteplici fattori, come mancanza di germoplasma selez…
