È possibile tracciare un bilancio sull’eucalitticoltura in Sicilia e sulle sue prospettive?
2017
La storia dell’eucalitticoltura in Sicilia è ormai una storia di mezzo secolo. La diffusione dell’eucalitticoltura in Sicilia e nelle regioni meridionali in genere ha corrisposto alla diffusione di un modello nuovo per queste realtà. Diversi errori sono stati compiuti soprattutto con riferimento alle scelte tecniche compiute a posteriori (scelta delle stazioni, assenza di cure colturali, utilizzazioni improprie). Un rinnovato interesse per questi popolamenti è derivato dalle opportunità offerte per l’utilizzazione energetica. Tuttavia anche questo approccio mostra i suoi limiti legati alla necessità di ricorrere a grossi volumi di legname e ad un utilizzo delle risorse legnose forestali sic…
Dynamics of fungal colonization in a new medical mycology laboratory
2012
International audience; Objective of the study. - Study of the spatio-temporal fungal colonization in a new medical mycology laboratory. Methods. - A 17-month survey of airborne fungal contamination was conducted in a new medical mycology laboratory at a tertiary care university hospital. This survey was implemented at three different periods: before the new premises were occupied (period A), during the move into the new laboratory (period B) and after resumption of the mycological activities in these new premises (period C). Results. - During period A, the airborne fungal load ranged from 2.3 to 6 cfu/m(3). The most frequently recovered airborne fungi were Penicillium spp. (75 to 100%). Du…
Essential Oils in Limiting the Development of Various Origins of Phytopathogenic Fusarium Isolates from Wheat Kernels
2022
The aim of the study was to determine the relationship between the chemical composition of eight commercial essential oils (EsO) (grapefruit, lemongrass, tea tree (TTO), thyme, verbena, cajeput, Litsea cubeba and garlic) and their fungistatic activity in relation to four species of Fusarium from the Polish population (F. avenaceum FAPL, F. culmorum FCPL, F. graminearum FGPL and F. oxysporum FOPL) and five from the German population (F. culmorum FC1D, F. culmorum FC2D, F. graminearum FG1D, F. graminearum FG2D and F. poae FP0D). In addition, the identification of EsO as potential biofungicides. Phytopathogenic fungi obtained from infected wheat kernels. The species identification of Fusarium …
Effects of migratory status and habitat on the prevalence and intensity of infection by haemoparasites in passerines in eastern Spain
2013
Efectos del estatus migratorio y del tipo de habitat sobre la prevalencia y la intensidad de la infeccion por hemoparasitos en paseriformes en el este de Espana La peninsula iberica es un sitio idoneo para estudiar los efectos de la condicion migratoria en la prevalencia de hemoparasitos en comunidades de aves, dado que convergen poblaciones residentes locales con especies migratorias y abundantes poblaciones de vectores. En este trabajo examinamos la incidencia de hemoparasitos presentes en aves de tres localidades de la region mediterranea (este de Espana), con respecto del estatus migratorio. Examinamos 333 frotis sanguineos de 11 especies, y encontramos una prevalencia global del 9,6%. …
Micropropagation of Citrus spp. by Organogenesis and Somatic Embryogenesis.
2013
Citrus spp., the largest fruit crops produced worldwide, are usually asexually propagated by cuttings or grafting onto seedling rootstocks. Most of Citrus genotypes are characterized by polyembryony due to the occurrence of adventive nucellar embryos, which lead to the production of true-to-type plants by seed germination. Tissue culture and micropropagation, in particular, are valuable alternatives to traditional propagation to obtain a high number of uniform and healthy plants in a short time and in a small space. Moreover, in vitro propagation provides a rapid system to multiply the progeny obtained by breeding programs, allows the use of monoembryonic and seedless genotypes as rootstock…
Production of the Sicilian distillate “ Spiritu re fascitrari ” from honey by-products: An interesting source of yeast diversity
2017
The “Spiritu re fascitrari” (SRF) is a typical Sicilian distillate obtained from the by-products of traditional process of honey production. Although some alcoholic fermentation of honey based products have been described, the present research represents the first investigation on the yeast ecology and the physico-chemical characteristics of honey by-products subjected to an alcoholic fermentation followed by distillation. All samples collected during manufacturing process were analysed for the count of total, osmophilic and osmotolerant yeasts. The honeycombs and equipment surfaces showed the presence of yeasts that was 1.7 and 1.1 Log (CFU/mL), respectively. After enrichment, yeast popula…
Could halophilic archaea improve the traditional salted anchovies (Engraulis encrasicholus L) manufacture?
2008
Although initial interest on extremely halophilic archaea turned to their involvement in the spoilage of salted meat and fish products, studies on the occurrence of such microorganisms in food ecosystems have rarely been performed. During salted anchovies production, a traditional process used by Mediterranean fishermen to obtain a tender product with a specific pleasant aroma and taste, extremely halophilic archaea belonging to the Halobacteriaceae family are often isolated. In order to elucidate the influence of halobacteria in salting and curing of this product, an experimental manufacturing was performed according to a traditional procedure. Salt to be employed was artificially inoculat…
Physicochemical Characterization, Antioxidant Activity, and Phenolic Compounds of Hawthorn (Crataegus spp.) Fruits Species for Potential Use in Food …
2020
Hawthorn belongs to the Crataegus genus of the Rosaceae family and is an important medicinal plant. Due to its beneficial effects on the cardiovascular system and its antioxidant and antimicrobial activity hawthorn has recently become quite a popular herbal medicine in phytotherapy and food applications. In this study, physicochemical characterization (color parameters, pH, titratable acidity, total soluble solids, soluble carbohydrate, total carotenoid, total phenols, and flavonoid contents), antioxidant activity (by ferric-reducing antioxidant power, FRAP assay), and quantification of some individual phenolic compounds of fruits of 15 samples of different hawthorn species (Crataegus spp.)…
Phlebiopsis gigantea attīstība un antagonisms pret Heterobasidion spp. parastās egles un priedes koksnē
2018
Pētījuma mēķis bija analizēt celmu apstrādes kvalitāti un P. gigantea attīstību egļu celmos, un novērtēt P. gigantea suspensijas koncentrācijas ietekmi uz sēnes attīstību skuju koku koksnē. Apstrādes kvalitātei ar P. gigantea ir noteicoša loma egļu celmu aizsardzībā. Eksperimentā novērtēja celmu virsmas pārklājumu ar preparātu ‘Rotstop’ un P. gigantea attīstību atkarībā no apstrādē izmantoto caurumiņu diametra zāģa sliedē. Celmu apstrāde veikta izmantojot četras zāģa sliedes ar izurbtiem atšķirīga izmēra caurumiņiem, un standarta zāģa sliedi no ražotāja. Pēc gada no celmiem ievākti un analizēti paraugi. Urbumu diametrs būtiski neietekmēja P. gigantea aizņemto laukumu celmos. P. gigantea att…
Growth and Antagonism of <i>Trichoderma</i> spp. and Conifer Pathogen <i>Heterobasidion annosum</i&a…
2012
Variations in the radial growth rate of 24 isolates belonging to ten species of Trichoderma, three isolates of conifer pathogen Heterobasidion annosum s.s. and four isolates of H. parviporum were evaluated by incubation on a solid malt extract medium at a temperature of 4℃, 15℃ and 21℃. Trichoderma antagonism against Heterobasidion was investigated in dual culture in vitro. The slowest rate of growth was referable to all seven strains of Heterobasidion spp. All Heterobasidion spp. strains were overgrown by 63% of Trichoderma spp. strains after two weeks at 21℃ and by 33% of strains at 15℃. 21% of Trichoderma strains did not grow and only four strains belonging to T. koningii, T. viride and …
