Microbial community characterization during anaerobic digestion of Scenedesmus spp. under mesophilic and thermophilic conditions
2017
[EN] Microbial communities were thoroughly characterized in a mesophilic anaerobic membrane bioreactor (AnMBR) and a thermophilic continuous stirred tank reactor (CSTR), which were both treating recalcitrant microalgal biomass dominated by Scenedesmus. 16S rRNA amplicon sequencing analysis was performed when the AnMBR achieved 70% algal biodegradation and revealed high microbial diversity, probably due to the high solid retention time (SRT) of the AnMBR configuration. The bacterial community consisted of Chloroflexi (27.9%), WWE1 (19.0%) and Proteobacteria (15.4%) as the major phyla, followed by Spirochaetes (7.7%), Bacteroidetes (5.9%) and Firmicutes (3.6%). These phyla are known to exhibi…
Ethnobotanical uses of wild taxa as galactagogues in Sicily (Italy)
2018
<p>Breastfeeding furnishes optimal nutrition, immune support, and a multitude of health benefits to mothers and newborns. Since ancient times plants have been employed as galactagogues in the folk medicine of many human cultures. In Sicily, a region with great floristic diversity in the Mediterranean area, where a conspicuous pool of species is traditionally used for food and aromatic, cosmetic, handicraft, agricultural, forestry, and medicinal purposes, some people recognize the galactagogue properties of some spontaneous plants.</p><p>The goal of this study was to identify wild plants with galactagogue properties and vegetable-food remedies traditionally used by women du…
Effect of a co-substrate supply in a MBR treating shipboard slop: Analysis of hydrocarbon removal, biomass activity and membrane fouling tendency
2018
The paper reports the main results of an experiment carried out on a membrane bioreactor (MBR) plant designed for the treatment of shipboard slops. With a view of a co-treatment process of the slop with other wastewaters, sodium acetate, as external co-substrate, was supplied (high dosage – Period 1, low dosage – Period 2) to evaluate its effects on hydrocarbons removal. The MBR pilot plant enabled approximately 99% of total petroleum hydrocarbon (TPH) removal during the entire experiment, confirming the robustness of the MBR technology for the treatment of slops. The chromatography/mass spectrometry analysis showed that the removal efficiency for each alkane was close to the value observed…
Biopreservation of Myoglobin in Crowded Environment: A Comparison between Gelatin and Trehalose Matrixes.
2017
Biopreservation by sugar and/or polymeric matrixes is a thoroughly studied research topic with wide technological relevance. Ternary amorphous systems containing both saccharides and proteins are extensively exploited to model the in vivo biopreservation process. With the aim of disentangling the effect of saccharides and polypeptidic crowders (such as gelatin) on the preservation of a model protein, we present here a combined differential scanning calorimetry and UV-vis spectrophotometry study on samples of myoglobin embedded in amorphous gelatin and trehalose + gelatin matrixes at different hydrations, and compare them with amorphous myoglobin-only and myoglobin-Trehalose samples. The res…
Biotechnology a Source of Knowledge in Agreement with Green Strategies for the Conservation of Cultural Assets
2019
In this study, conservative strategies are applied in order to limit any irreversible damage and to characterize and quantify microbial colonization that may induce the deterioration of constitutive heritage materials; subsequently, suitable antimicrobial interventions are performed based on the use of biotechnology. This paper presents a summary of the basic and applied biotechnology research developed in the Laboratory of Biology and Biotechnology for Cultural Heritage (LaBBCH, University of Palermo, Italy). It shows that biotechnology has an evidently important role in the preservation and restoration of cultural assets, also taking into consideration that “Prevention is better than cure…
Le bien-être alimentaire du quotidien à l’institution hospitalière : de nouveaux enjeux normatifs.
2020
Cet article interroge la façon dont les questions sanitaires jouent sur les normes en matière de santé. Dans une perspective diachronique et culturellement située, l’objectif de l’article sera, dans un premier temps, de montrer que le bien-être est une valeur évolutive aux prismes des attentes sociétales. D’un bien-être aux contours fermés et délimités, les enjeux sociaux et la forte médiatisation de la nutrition en font une valeur qui évolue, dont la qualification reste toujours difficile à saisir. Dans un second temps, l’article propose la construction d’un outil de mesure du bien-être alimentaire en contexte hospitalier afin d’intégrer des éléments subjectifs et actuels autour des attent…
ACTIVIDAD FÍSICA Y DISCAPACIDAD: UN ESTUDIO CUALITATIVO CON MUJERES EN UN GIMNASIO ADAPTADO
2017
Este estudio explora cómo un grupo de mujeres con discapacidad (n=6) experimentan y perciben la práctica de actividad física en un gimnasio adaptado. Se utilizaron entrevistas semi-estructuradas como instrumento de recogida de datos cualitativos y se realizó un análisis temático inductivo. Los resultados se agruparon en torno a cuatro categorías temáticas emergentes: condición física y autonomía personal; papel paliativo del ejercicio; bienestar psicológico; relación social y apoyo. Destaca la experiencia satisfactoria de las participantes, en la que predomina una valoración positiva de procesos autorregulativos, la concepción social-relacional de la actividad física, y la relevancia del gi…

The first year of the “open discovery of stem laboratories” (ODL) project
2018
The Open Discovery of STEM Laboratories (ODL) project, co-funded by the European Community Erasmus+ KA2 program for 30 months, starting from November 2015, involves five countries: Spain, Italy, Greece, Estonia and Lithuania. It aims to implement teacher collaboration in creating and using μMOOCs (very short version of MOOCs-Massive Open Online Courses) for encouraging the use of STEM (Science, Technology, Engineering and Mathematics) remote/virtual laboratories into lessons. The challenge of the project is to impact on teaching process and inspire pedagogical innovation and modernization by means of open education resources, teaching/learning tools and best practices provided by European e…
Convivencia en el ámbito educativo: aplicación de un programa basado en la empatía, la educación emocional y la resolución de conflictos en un instit…
2019
La educacion emocional y la resolucion de conflictos son factores clave en la mejora del clima del aula. Asi lo demuestra nuestra experiencia contextualizada en un centro de secundaria de la ciudad de Valencia (Espana) con un alto indice de expedientes sancionadores. La puesta en practica, en dicho centro, de un programa de intervencion y formacion para entrenar las tecnicas relacionadas con la educacion emocional y la resolucion pacifica de los conflictos ha supuesto una reduccion significativa tanto en el numero de expedientes como en la manera de afrontarlos traduciendose en una mejora de la convivencia en el centro mediante un aumento de la Cultura de Mediacion.
